 When I first read the field notes of Annie Alexander and Louise Kellogg, I was fascinated by the descriptions they wrote about the places they went and the plants and animals they found there. By publishing my field notes on the Internet I hope to follow a little bit in their tradition.

Downhill view from the spring.
From the stream crossing on the City of Golden trail, climbed up the slope to find the spring. It is at the top of the second run, and at the base of a thicket. The spring has been “improved” in two locations. One has a 1 inch black plastic pipe coming out ot a small thicket. Presumably there was a small spring box that is now overgrown. The other improvement is a small metal drum that has been cut open and laid sideways in the watercourse. This probably ensured a small pool of water for wildlife to drink. The drum is now filled with rocks. Above the spring is the head scarp of a large landslide on which the surface is level to sloped back toward the mountain.

From the head scarp I went north to the North Table Mountain Trail, then up the social trail to the top of the mesa. I checked the spoils pile for Astragalus, then returned by way of the Golden Cliffs Trail, stopping to verify the location of Munroa squarrosa.

Other articles: Mono Lake Basin Flora at Deep Caon  

“In the wrinkled, sage-covered mountains of Nevada near the California border, 30 miles east of Mono Lake, there is a meadow that seems to lie in shadow even on sunny days. Spread across it are hundreds of dark patches, where the soil is mixed with charcoal. These spots lay row upon row, like the ghostly foundations of a dead city. In a sense, that is exactly what they are.

“In 1967, workers with the Forest Service and the Department of Defense stacked 342 piles of juniper and pion logs in this place 20 tons of wood per pile, spaced 25 feet apart. Then, at 8 a.m. on Sept. 29, they set fire to them.

“Project Flambeau comprised some two-dozen experiments like this one, meant to simulate an American suburb under nuclear attack (Fox, 2017)”

ERIGERON COMMIXTUS. With the habit of E. flagellaris, smaller, less stoloniferous, the leaves relatively broader, some entire, others with one or more conspicuous lobes at base of the blade, the whole plant almost hoary with a stiffly hirsute pubescence, this spreading on the leaves and petioles, retrorse on the stems and peduncles : heads, rays, achenes, etc., much as in E. flagellaris.

Canon of the Limpia, mountains of western Texas, 26 April, 1902, S. M. Tracy and F. S. Earle; also collected by the present writer, in the same general region, namely, in the mountains near Silver City, New Mexico, 18 May, 1880, and distributed for E. flagellaris. The species last named has a rather obscure, fine closely appressed hairiness. That of the new one is so extremely different, that were the plants of the size of a Sunflower or Goldenrod, no botanist would confuse them as one species, were the pubescence the only character. I may remark that true E. flagellaris reaches the mountains of even southern New Mexico, where, however, it occurs only in a more elevated biological zone.

We now treat E. commixtus as a synonym of E. tracyi.

ERIGERON TRACYI. Allied to the last but dwarf, only 2 or 3 inches high, densely leafy at base and with no stolons (at least at flowering time): petioles of the spatulate-lanceolate entire leaves shorter than the blade or obsolete; the whole herbage silvery-hoary with a fine dense strigulose pubescence, or this more sparse and spreading on the solitary scapiform peduncle: involucre hispidulous: outer pappus very conspicuous though consisting of only shorter and setiform hairs, the inner of a few very delicate capillary ones.

1682  Field identification: Potentilla norvegica.

This turned out to be a mixed collection of similar taxa in Potentilla Sect. Rivales. FNANM shed some light on this section:

The North American representatives of sect. Rivales are morphologically distinctive in being annuals, biennials, or short-lived perennials (especially in cold regions) with very short, conic-tapered styles. Plants grow primarily in wet habitats, especially where periodically inundated. These distinctions led E. L. Greene (1906c) to adopt Tridophyllum. However, the gross morphological cohesiveness is not matched by molecular monophyly. Instead, chloroplast data scatter Potentilla norvegica, P. rivalis, and P. supina among the core Potentilla, while P. biennis is sister species to the monophyletic Ivesia-Horkelia-Horkeliella clade (C. Dobe and J. Paule 2010; M. H. Tpel et al. 2011). Nuclear markers, on the other hand, place P. norvegica as sister to the Ivesia-Horkelia-Horkeliella clade (Tpel et al.), suggesting a possible hybrid origin and/or multiple origins of the biennial habit.

Existing herbarium annotations of Potentilla biennis, P. norvegica, and P. rivalis are not reliable, but the three species can be readily distinguished by vestiture of proximal petioles and stems. Only P. biennis has prominently septate gland-tipped trichomes; P. norvegica is characterized by relatively stiff, spreading, tubercle-based hairs to 3 mm, resembling those of P. recta. In addition, the tiny, smooth, pale achenes of P. biennis and P. rivalis contrast sharply with the larger, darker, strongly ridged ones of P. norvegica.

FNANM treat P. douglasii and P. majus as distinct while noting that P. majus is sometimes treated as a synonym of P. douglasii. Reading the descriptions of both, I lean toward P. majus for this collection. However, Ackerfield (2015) does not list P. majus for Colorado. Nearly all collections for Colorado are determined as P. douglasii, except for two Hall and Harbour collections at F. Weber & Wittmann (2012) explicitly list P. majus as a synonym for P. douglasii. For this collection, I will use P. douglasii, file it at JCOS and KHD, and then let the “Polygonistas” (or is it “Polygonarians?”) sort it out.

Royal Gorge

Lt. Zebulon Pike and his men, who traveled through this area in November and December 1806, were the first American explorers to view the Arkansas River canyon now known as the Royal Gorge. A small party from the Maj. Stephen H. Long expedition visited the mouth of the canyon in 1820, as did members of Lt. John C. Fremont's expedition in 1845.

In 1878 a right of way through the Royal Gorge became the focal point of a bitter struggle between the Denver and Rio Grande and the Atchison, Topeka and Santa Fe Railroads, with the D and RG eventually winning the route through court action. Congress ceded the land comprising the Royal Gorge Park to Caon City in 1906, and the world's highest suspension bridge spanning the Arkansas River 1053 feet below was built in 1929.

Elevation 6,626 feet.

Powderhorn Valley

Powderhorn Valley was named by mountain men and fur trappers because the shape of the valley resembles a bison horn that would have been used to keep gunpowder dry.

The Post Office in Powderhorn Valley was established in 1876 when the valley was settled by ranch families looking for lush grassland to support cattle. In the early years, Powderhorn Valley supplied beef and potatoes that fed the hungry miners and most of the hay for the horses, mules, and burros that worked in the mines in the mountains above Lake City.

For years, families shopped at Youman's store. Everything in the store was behind the counter and customers had to ask for needed items. Household goods, including fabric, nails, flour, and seed were available only in bulk and needed to tbe measured or weighed at the time goods were sold.

The Old Spanish Trail 1829-1848

Between 1829 and 1848 woolen goods were transported by mule caravans from the Mexican outpost of Santa Fe to the Missions of Southern California on the Old Spanish Trail.

Annual mule pack caravans traveled the historic Old Spanish Trail between Santa Fe, New Mexico and Los Angeles, California. Traders from Santa Fe headed to San Gabriel Mission as a welcome destination. They brought woolen goods from New Mexico and returned with highly prized California mules and horses. Following ancient Native American trails, the trade route went into central Utah during Spanish Colonial days and continued as an emigrant trail during the Mexican period. Anglo trappers and military expeditions, including John Fremont, Kit Carson, and John Gunnison used various routes of what is now recognized as the Old Spanish National Historic Trail.

In June 1853, Lieutenant Edward Beale, accompanied by Gwinn Harris Heap detailed their travel route through this area. Head wrote “ we crossed the two forks of the Jaroso (Cebolla Creek and Powderhorn Creek) we rested for the night by a small shallow brook, very marshy, and swarming with mosquitos Numbers of deer and antelopes were seen; indeed, these sheltered calleys seem expressly intended as coverts for those gentle animals Traders from Abiquiu come by it into these mountains to barter for peltries with the Utahs (Ute Indians).”

Lost in a Blizzard

“In the Colorado Rockies where the snow is deep and cold a man afoot can starve to death unless he's brave and bold.” -- Ballad of Alferd Packer

What is now recognized as one of the most notorious events in Colorado's history -- cannibalism by Alferd Packer -- unfolded in the valley below you. If was here that Alferd Packer and his men made a most disastrous mistake, then missed a turn in the trail and became hopelessly lost in the San Juan Mountains.

On that fateful day in February 1874, Alferd Packer became lost in a severe snow storm while guiding five men from Salt Lake City ti the Los Pios Indian Agency, located south of what is now Gunnison. At the time, the Old Spanish Trail was a well worn trail that continued on to Taos and Santa Fe. Unfortunately, snow covered the trail in the valley below and the hapless men continued to the south instead of remaining in the trail to the east.

Cannibalism in the high country could have been averted had they remained on the correct trail towards Cohetopa Pass.

Keeping the Peace

The trail is well worn, and the peeled trees show that the valley has been much frequented by (Ute) Indians.

Gold was discovered in the San Juan Mountains in the late 1860s leading to a rush of miners. Tension rose between the miners seeking gold and the Ute Indians who lived and hunted in the mountains. As a result, the U. S. Government negotiated the Brunot Treaty in 1873 with Chief Ouray and the Weminuche Ute.

At this point we passed the Great Gate, a rift in a spar sweeping around from range to range across the calley.” -- Lt. E. H. Ruffner, Corps of Engineers, Reconnaissance in the Ute Country, 1873

That same year, the military sent Lt. E. H. Ruffner into the San Juan Mountains to document mining operations in Southern Colorado and evaluate the effectiveness of the Brunot Treaty. Ruffner noted, “While at Camp 47 we were visited by many western Utes, mostly well armed, well mounted, and well dressed; uncommonly clean, smiling and civil; short men, with broad muscular shoulders.”

Interpretive panel for Lake City Caldera
A Volcanic History

Twenty million years ago this entire region was geologically active as massive volcanoes changed the face of the landscape.

If you were here 23 million years ago, you would be standing on the northern edge of that is now called the Lake City Caldera. As the magma chamber emptied from this massive volcano it could no longer hold its shape. The volcano collapsed and fell into itself. This formed the landscape we see today. Most of the rocks surrounding the caldera including granite, obsidian, basalt, tuff and pumice are direct evidence of this region's violent volcanic past.

A caldera is a caldron-like feature formed by the collapse of land following a volcanic eruption. With the collapse of the Lake City and Silverton calderas, a volcanic soup of minerals was injected into the surrounding rock. This produced a rich intrusion of silver, gold, lead, copper, tellurium, and iron. For millions of years, these deposits remained untouched until discovered by prospectors in the 1860s and 1870s.

Early Holocene Encampment

Nearly 10,000 years ago, archaic hunters and gatherers camped along the Lake Fork of the Gunnison River. Here they hunted wild game such as bighorn sheep and elk in these alpine valleys.

At the end of the last Ice Age, Archaic big game hunters skillfully hunted animals such as elk, deer, bighorn sheep, and a now extinct variety of bison (Bison taylori). Archaeological evidence indicates that these hunters camped along the Lake Fork of the Gunnison River. Stone tools found in these emcampments include bifaces, drills, scrapers, projectile points, and point fragments.

Near the end of the Ice Age, during a colder and wetter period of time, Archaic hunters lived in small bands. Indications are that they did not stay in any one place very long, but moved often in search of game animals.

Alferd Packer

You man eating son of a There was seven Democrats in Hinsdale County and you ate five of them.” -- Quote attributed to saloon keeper Larry Dolan after Alferd Packer's first trial.

In February 1874, Alferd Packer became lost in a severe snow storm while guiding five men from Salt Lake City to the Los Pios Agency , (south of Gunnison). In mid-April, Packer arrived at the Los Pios Agency -- alone. Upon interrogation, he claimed that as each person died the other men ate the flesh of the dead. Packer said he killed only one person, but only in self-defense. That summer, five bodies were discovered at this site. Each person's head had been crushed. Alferd Packer was arrested and accused of murder and cannabalism. Before his trial, however, he fled Colorado.

Nine years later, Packer was captured in Wyoming and was returned to Colorado. He was found guilty of manslaughter and sentenced to prison for forty years. After serving fifteen years he was paroled in 1901. Until his death in 1907, Packer maintained his innocence in one of the most notorious events in Colorado's history.

Slumgullion Earthflow

The Slumgullion Earthflow was listed on the Natural Registry of Natural Landmarks in 1965 and designated a Colorado Natural Area in 1983.

Imagine what it must have looked like as a massive block of rock, dirt, and forest broke away from Mesa Seco and an enormous earthflow oozed into the valley below. About 850 years ago, during a very wet period of time, a series of slow-moving landslides occurred. the largest landslide dropped over 3,000 feet in elevation and extended downhill more than four miles. What is now called the Slumgullion Earth flow altered the landscape on over 1,000 acres and created Lake San Cristobal.

The story, however, is not over. About 350 years ago, the most recent earthflow began to descend. This flow covered half of the older flows and is still active today. Geologists estimate that in places it is still moving downhill about twenty feet per year.

Slumgullion is a mining word used to describe the muddy clay left in the bottom of a sluice box. However, miners often cooked a hearty and colorful stew that resembles the color of the Slumgullion Earthflow.

Slumgullion Stew


1½ lb. stew meat

A massive portion of Mesa Seco gave way about 850 Years ago. This resulted in the Slumgullion Earthflow, one of the most visible examples of “mass wasting” in the United States.

About 850 years ago, thousands of tons of water-saturated, earthen material broke away from Mesa Seco and slid nearly four miles into the valley below. The Slumgullion Earthflow dammed the Lake Fork of the Gunnison River and formed Lake San Cristobal -- the second largest natural lake in Colorado.

About 350 years ago, another portion of Mesa Seco began to slowly ooze down the hillside. Riding above the older slide, this flow covered about 2.5 miles of the older flow. Geologists estimate that it is still moving downhill approximately twenty feet per year.

When gold and silver were discovered in the nearby mountains, these meadows at 10,500 feet in elevation became home to nearly 1,200 people. Between 1892 and 1896, this was the bustling community of Bachelor City. In January 1892, an eighty-acre town site was surveyed into twenty-four blocks with twelve streets. By March of 1892, nearly 100 ramshackle houses had been hastily constructed.

In its heyday, Bachelor City had a dozen saloons, four hotels, five grocery stores, a meat market, two barber shops, two bakeries, several restaurants, a school, a jail, city hall and a Catholic Church with a parsonage. Bachelor City had a doctor and a dentist and the town newspaper, the “Teller Topics.”

“The camp was a bustling one, and its citizens composed of the rougher reckless types of Westerners, men who neither feared nor shunned danger, and to whom 'knockdown and dragout' fights were merely ordinary recreation. Brawls and pistol-play were a nightly occurrence in the numerous saloons and gambling dens that infested the place the character of Bachelor remained tough.” -- Bachelor City - 1892

Wagon Wheel Gap -- The Early Years

In the early part of the twentieth century, railroad passengers, tourists, and health seekers boarded wagons at Wagon Wheel Gap and ventured to the Hot Springs Hotel to partake in the rejuvenating water.

The Denver and Rio Grande Railroad touted the healing qualities of the hot springs located near Wagon Wheel Gap. These springs soom became a destination for health seekers.

In December, 1848, John Fremont led an expedition into the San Juan Mountains to find a route for the transcontinental railroad. The ill-fated expedition may have traveled up Embargo Creek, (to the east of Wagon Wheel Gap), where they encountered a vicious winter storm. With ten feet of snow and deteriorating conditions, Fremont abandoned his expedition and each man fended for himself. All told, ten of Fremonts men died of cold or starvation in the San Juan Mountains.

In 1863, Charles Baker led a group of prospectors into the San Juan Mountains. While returning to New Mexico for the winter, then abandoned a damaged wagon near the “gap” where the Rio Grande carved a small canyon. In the 1870s, a wagon wheel was discovered in this area and it was believed to be a remnant from the Baker party. Miners referred to this area as “the gap where the wagon wheel was found.” Over time this area became known as Wagon Wheel Gap.

Wheeler Geologic Area was named in honor of George M. Wheeler, who surveyed much of Colorado in 1874. The area was designated a National Monument in 1908 by President Theodore Roosevelt in part to protect the highly erodible spires, hoodoos, and geologic formations. Due to its isolated location and diffifult access, the area was delisted as a National Monument in 1933. Wheeler Geologic Monument is now managed by the Rio Grande National Forest.

Penitente Canyon: Special Recreation Management Area
A place of solitude ... a place of mystery .. a place with a spirit of its own ... Penitente Canyon
In the mid-1980s, rock climbers discovered the Penitente canyonlands. Today the BLM manages the area primarily for climbing, though mountain bikers, hikers and people drawn to its sense of peace and history also make their way to the canyons.
History

Ancestors of the Utes, Jicarilla Apaches and Puebloans have all left evidence of time spent hunting and camping here, along with explorers and trappers. The valley's first settlers were Hispanic farmers and sheepherders who migrated from northern New Mexico.

Virgin of Guadalupe

It's said that in the mid-20th century a few men from the local community painted the image of the Virgin of Guadalupe that's still visible today. Local legend has it that they sat in tires and were lowered over the cliff on ropes to complete the painting. The words above the Virgin read “Consuelo y Spiritu” or “Comfort and Spirit.”

Ecology

Penitente Canyon is home to many varieties of plants including chokecherry, wild rose, fringed sage and aspen; and wildlife including black bear, mountain lion, raptors, various lizards and prairie rattlesnakes.

Snakes

Always watch where you are stepping or reaching; don't reach where you can't see. If you encounter a snake, leave it alone and back away. Parents should always keep a close eye on their children in snake country.

Stay Safe

Safety is your responsibility. Know your limits and come prepared for the area's changing weather. All recreational activity is at your own risk.

Early Explorers: Filling in the Blanks

Ellen Thompson, Expedition Botanist

Ellen Thompson, wife of A. H. Thompson and sister of John Wesley Powell, served as botanist on the sedond Powell Expedition. She collected hundreds of plants, many of them new to science. Several were named in her honor, including Thompson's Penstemon (Penstemon thompsoniae) and Thompson's Woolly Locoweed (Astragalus mollissimum var. thompsoniae). Mount Ellen, in the Henry Mountains, is also named for her.

“I never felt more exultant in my life ... I was looking on the most wonderful scenery I ever beheld.”

Andrus Expedition, 1866

“... as far as the Eye can see a naked barren plain of red and white Sandstone crossed in all directions by innumerable gorges ...” -- Franklin B. Woolley, Andrus Expedition, 1866.

Several years before the Powell Expedition, the Andrus military expedition patrolled the Aquarius Plateau region, providing the first written descriptions of this area.

Mapping the Last Uncharted Lands

By 1870, the continental United States had been mapped and surveyed, except for one area -- the vast region that surrounds you. From the Colorado River to the Aquarius Plateau, and from the Virgin River to the Green, this rugged landscape was uncharted territory.

Though the Fremont Expedition passed through Capitol Reef during the winter of 1853-54, they were desperately low on provisions and did not linger to survey the region. In 1872, John Wesley Powell launched his second expedition down thw Green and Colorado Rivers to chart the Rivers and surrounding lands. Over the next four years, his brother-in-law, Almon H. Thompson, led the land survey of southern Utah, during which he explored and charted Boulder Mountain and the rest of the Aquarius Plateau. The expedition also named and mapped the Escalante River and the Henry Mountains, respectively the last-mapped river and mountain range in the lower 48 states.

Lay of the Land: Across a Vast Horizon

“To a life that accepts Nature's hand in sculpting an individual expression – Nothing is exempt.

From the mellifluous rhythm and tome of the wid chime, to the transitional form of the cloud – Nothing exists alone.

All things thrive and whither in confluence with one another.

So it is; the paradox of our divinity.”

– Dave Buschow

Waterpocket Fold

The 100-mile-long Waterpocket Fold forms the backbone of Capitol Reef National Park. Here, geologic rock layers drape over a steeply dipping fault plane. Over millennia, water and wind have eroded the soft layers, sculpting the Waterpocket Fold's intricate contours. Along the Fold, water collects in sandstone basins, forming “waterpockets.”

Circle Cliffs

Within this section of Grand Staircase - Escalante National Monument lie huge petrified wood logs, some nearly 90 feet long. These rocks formed from trees that grew some 210 million years ago. The logs were buried in river sediments and became “petrified” as silica from volcanic ash gradually replaced organic cell tissue.

The Heart of the Escalante

“The Aquarius should be described in blank verse and illustrated upon canvas. The explorer who sits upon the brink of its parapet looking off into the southern and eastern haze, who skirts its lava cap or clambers up and down its vast ravines, who builds his camp fire by the borders of its snow-fed lakes or stretches himself beneath its giant pines and spruces, forgets that he is a geologist and feels himself a poet.”

– Clarence Dutton, 1880

The wild heart of the Escalante River drainage spreads before you – a labyrinth of canyons, mesas, and rolling slickrock. Remote peaks grace the horizon. On the far left lie the Henry Mountains, the last-named mountain range in the continental United States and home to one of the country's few free-roaming bison herds. Follow the horizon south, and you'll reach the rounded dome of Navajo Mountain on the Utah-Arizona border.

Second Powell Expedition: Charting New Territory

Powell Point Recollections

“We still keep Table Mountain (Pink Point) to our left this singular mountain suggests a monster melon, sliced and standing on end. It is exactly the color of a ripe, red core; the pines that grow on ledges and benches, black specks at this distance, look like weeds.”

– Walter Clement Powell, member of the Second Powell Expedition of 1871, describing their ascent of the Blues Formation to the base of Powell Point.

The Topmost Stair

Powell Point reveals the topmost layer of the Colorado Plateau's Grand Staircase. This brilliantly colored layer, known as the Pink Cliffs or Claron Formation, is the same geologic layer that forms the spectacular, pinnacled landscape of Bryce Canyon National Park and Red Canyon, farther west on Highway 12.

Last Blank Spot on the Map

In 1871, this region was part of the last uncharted territory in the continental United States. That year, Major John Wesley Powell launched the Second Powell Expedition to explore and map this frontier, continuing the work he had begun three years earlier. Powell led the expedition safely through the wild waters of the Green and Colorado Rivers to the Paria River. He then instructed his brother-in-law Almon H. Thompson to lead the expedition overland to map what they called “the unknown country.” In 1872, expedition members climbed the slippery slopes of the badlands on which you now stand. Thompson then scaled the brilliant pink formation above you to view the surrounding country. Over the next four years, Thompson's explorations filled in this last blank spot on the U. S. map. In 1879, surveyor Clarence Dutton named this spectacular landmark “Powell Point,” in honor of Major Powell. Highway 12 now follows the 2nd Powell Expedition's exact route from Henrieville all the way to Head of the Rocks, east of Escalante.

Digging for Dinosaurs: Treasure in These Hills

Why Here?

The Kaiparowits Formation's stunning fossil record results from a perfect combination of circumstances. First, during the Late Cretaceous, this region was a lush, subtropical, coastal plain where an enormous number and variety of animals lived. Second, abundant rivers and coastal storms moved great volumes of sand and mud, so animals that died were sometimes buried quickly, preserving their remains. Lastly, uplifting of the Colorado Plateau over the past 60 million years has brought this deeply buried treasure to the surface.

Scientific Frontier

In a region famed for once being the last unmapped frontier in the continental United States, the Kaiparowits Formation remains a largely unexplored frontier. By protecting the fossils of this formation through proper collection and study, Grand Staircase - Escalante National Monument conserves a vast storehouse of knowledge available nowhere else on earth.

Kaiparowits Fossil Bonanza

There's treasure beneath your feet. Not of the gold-and-rubies variety, but rather a treasure of fossilized bones, eggshells, and other paleontological gems, buried in these gray rock formations some 73-77 million years ago. Known as the Kaiparowits Formation, these sedimentary rock layers lie at the top of what is perhaps the best and most continuous record of Late Cretaceous terrestrial life in the world.

Forty-foot long crocodiles, rhinoceros-like horned dinosaurs. tyrannosaurs, and velociraptors – all lived here. Scientists have surveyed only a small fraction of the Kaiparowits Formation, and have unearthed more than one hundred species of vertebrates. Excavations are revealing a long-lost ecosystem inhabited by a fantastic array of animals, including some of the earliest marsupial and placental mammals ever found. These disoveries are helping to explain the origins of our present world.

Saving the Redwoods

As spectacular as these redwood forests are, their protection was slow to gain broader support.

One of the earliest organized efforts to save the redwoods was led by the Sempervirens Club. In 1902, they convinced the California legislature to appropriate funds for the purchase of the first state redwood park. Congressman William Kent also joined the effort. He personally bought and donated 295 acres of redwoods outside San Francisco to the federal government. His gift led to the creation of the Muir Woods National Monument in 1908.

Save the Redwoods League was founded in 1918 to purchase redwoods and convert the land to public trust. Numerous groves were protected and redwood state parks created through the League's efforts, including Del Norte Coast Redwoods, Jedediah Smith Redwoods, and Prairie Creek Redwoods State Parks.

A renewed effort to establish a national redwood park began in the early 1960s. These efforts were augmented in 1963 when a National Geographic survey team discovered several trees along Redwood Creek that were taller than any previously known. This discovery helped lead to the establishment of Redwood National Park in October of 1968.

Lewis and Clark Expedition

Rooster Rock

Meriwether Lewis and William Clark, the two great American explorers who made secure the claim of the United States for the Oregon country, passed along this stretch of the Columbia River with their Corps of Discovery on their way to the Pacific Ocean on October 31 -- November 2, 1805. They brought their boats through the “Great Shute” (now covered by the waters of Bonneville Dam) and recorded “a remarkable high detached rock stands in a bottom on the stard side ... [it is] 800 feet high and 400 paces around, we call [it] the beaten rock.” A later journal entry called it Beacon Rock.

The captains described “great numbers of sea otters” and “a high clift of black rocks” (Cape Horn) on the north shore. Clark wrote “here the river widens to near a mile, and the bottoms are more extensive and thickly timbered, as also the high mountains on each side ... passed a rock near the middle of the river, about 100 feet high and 80 feet diameter [Phoca Rock] ... we encamped under a high projecting rock on the lard [Rooster Rock].”

The expedition camped in this area April 6-9, 1806, on their return journey. They noted that Beacon Rock “may be esteemed the head of tidewater.”

Red Rock Pass Geological Site

About 14,500 years ago, ancient Lake Bonneville overflowed at this site. A dam of alluvial fans between Oxford Mountain to the west and the Portneuf Range to the east suddenly eroded releasing Lake Bonneville from the Great Basin into the Snake River system. The Peak flow was about one million cubic meters per second at the pass, or about 500 times the maximum discharge on the Snake River at Idaho Falls, Idaho. Ancient “bathtub ring” shorelines up to 1,000 feet above the valley floor are readily visible in the Salt Lake Valley. Evidence of the flood is visible thoughout southern Idaho with areas of scoured bare bedrock (“scabland”) and deposits of boulders (“melon gravel”) marking the flood path. After about 11,000 years, Lake Bonneville receded to become the Great Salt Lake. Highly saline and only 40 feet deep, it is but a shadow of giant fresh-water Lake Bonneville.

Red Rock Pass is the geographic northern extremity of the Bonneville drainage basin, and was also designated by the early Latter-day Saint leaders as the northern edge of the proposed State of Deseret. North of here, water flows to the Snake, Salmon, and Columbia rivers, on the way to the Pacific Ocean, but south of here it flows into the Great Basin and the Great Salt Lake.

South of the monument in Red Rock Pass, the house-sized limestone blocks were jostled during the breakout of the Bonneville flood. The uneven topography northwest of the monument is a landslide which flowed into Red Rock Pass after it was deepened about 400 feet during the flood. Ancient cave formations are found in the flat-lying limestone of Red Rock Butte immediately north of the monument.

Red Rock Pass

You are standing in the outlet of ancient Lake Bonneville. A vast prehistoric inland sea, of which Salt Lake is a modern remnant.

Covering over 20,000 square miles when it overflowed here about 14,500 years ago, its winding shoreline would have stretched from here to New Orleans if it were straightened out. This pass was deepened considerably when Lake Bonneville began to slow into Snake River. For a time, a torrent several times larger than the Amazon was discharged here. Finally, with a hotter, drier climate that slowly emerged about 8,000 years ago, Lake Bonneville gradually disappeared.
