 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.

Note on Smooth Brome One of the most common non-native species found at nearly every site was smooth brome (Bromopsis (Bromus) inermis). Smooth brome is not on the noxious weed list, yet it appears to be one of the largest threats to ecosystems, besides development, in Jefferson County, particularly in wetlands. Smooth brome is very difficult to treat without causing problems to the surrounding environment. Unfortunately, the spread of smooth brome is being encouraged by weed treatment activities especially in wetlands. Canada thistle is very common in wetlands, and is a B-List noxious weed. It is often treated with herbicides that impact dicots. Smooth brome is a monocot. A recent report by Rondeau (2011) found in a six year monitoring effort for Canada thistle (Cirsium arvense, also Breea arvensis) that although the treatments were successful in removing the Canada thistle it was replaced by smooth brome in wetlands where smooth brome was already in the area. In addition, they found the local native plants including woody species were being impacted as well over the six year study. Overall the result was a less desirable outcome than the situation being remedied from an ecological perspective. This is unfortunate because Canada thistle is a B-Listed plant; people are being required to treat it. If smooth brome is in the vicinity (which is often the case) a state listed noxious weed is being replaced by something that is even more difficult to control and arguably more damaging to the ecosystem. In the State of Colorado, smooth brome is available for use in seed mixes used by ranchers, homeowners and highway departments which is why it is not listed as an invasive species. This plant is considered to be an invasive species in at least ten other states (MN, OH, IN, IL, KY, TN, NB, WI, ND and MS), by Ivasives.org and The Nature Conservancy.

Dolmen de Matarrubilla

The Matarrubilla Dolmen was discovered in 1917, also as a result of some agricultural tasks. It is just one kilometer in a straight line from La Pastora,

As a funerary corridor and circular chamber structure with a total length of 32 meters, Matarrubilla approaches La Pastora in grandeur. It differs fundamentally because in the chamber is a great block of black marble, carved and with a recess of several centimeters on the upperpart, that probably fulfilled functions of table of offerings or altar. Undoubtedly it is a ritual element that already had great importance in the design and planning of the monument, since its placement, occupying much of the space of the chamber, must have occurred before the erection of the roof in a false dome.

The funeral deposit found in Matarrubilla was quite scarce. In the plundered chamber were scrambled and fragmented remains of pottery and some human bones. In the corridor, some materials were in situ, including stone tools, a large number of fragments of gold lamellae, some ivory objects (including an elephant tusk in the rough, unworked) and several thousands of necklace beads. Only one complete skeleton was found, halfway down the corridor and in a cramped position. The relatively low number of burials and grave goods and the presence of the altar or offering table that so clearly dominates the space available in the vaulted chamber of the monument suggests that, indeed, a monument such as Matarrubilla may have played the role of a temple or ceremonial enclosure besides (or perhaps more than) a sepulcher ( https://www.rutasconhistoria.es/loc/dolmen-de-matarrubilla ).

Packera Lve & Lve, gen. nov.

Plantae perennis, herbaceae. Caules non rite foliosi. Caudex sine rhizoma repens vel suberectus. Folia simplicia et integra ad lyrato-pinnatifida, folia radicalia petiolata, caulinaria amilia vel minora. Plantae glabratae alteruter ab initium vel plus minusve permanentes tomentosae; pubescentia nunquam e pilis longis articulatisque. Numerus basicus chromosomatum x = 23. Typus generis: Packera aurea (L.) Lve & Lve.

Herbaceous perennials. Stems not uniformly leafy to the inflorescences, arising from a horizontal to suberect caudex or rhizome. Leaves simple and entire to lyrate-pinnafitid, those at the base petiolate, gradually reduced upwards, or uniform throughout. Plants either quite glabrous from the beginning or more or less permanently tomentose; pubescence never of long jointed hairs. Basic chromosome number x = 23.

This mainly North and South American genus with a few representatives in Asia comprises the groups Aurei, Lobati and Tomentosi of the collective genus Senecio as described by Rydberg (1900) and Greenman (1916), which stand apart from the other divisions of the collective aggregate by having prolonged rhizomes, and if pubescence is present it is a tomentum of more or less arachnoid and never of long and jointed hairs, but persistent as flocculent tufts. Its morphological and geographical distinctions are enhanced by its basic chromosome number, which differs markedly from that of Senecio L. s. str. (x=10) and Tephroseris (Rchb.) Rchb. (x = 8) so that its distinction as a genus is biologically well substantiated. It is our pleasure to name the new genus in honour of John G. Packer, an oldtime friend who has contributed much to the clarification of the status of the arctic-alpine North American members of the taxon.

Auto Tourism

Highway 14

The first Highway over Cameron Pass, completed in 1882 but the Cache la Poudre and North Park Toll Road Company, ran more than one hundred miles from Fort Collins to the silver camp of Teller. Travelers paid three dollars per wagon, with additional fees for herd and pack animals, for the privilege of laboring up a demanding, boulder-strewn route. Some stretches were so hard to navigate (especially steep Pingree Hill) they left teamsters cursing in frustration. Opened to free public travel in 1902, the road received much-needed improvements in the 1910s, with a smoother surface and an easier grade carved out by convict laborers. When the road reopened in 1915, two hundred automobiles drive to a celebratory picnic at milepost 109 (about forty miles east of here), motoring with ease over the once formidable route — and heralding a new generation of auto tourism.
The Autobungaloofer, seen here in 1921, epitomized America's craze for auto tourism. Serene mountain towns cleared trees and shrubs to make room for homes on wheels. For those who didn't think to bring the house with them, motels were built, while Mom and Pop made room for convenience stores, gift shops, and bait shops.
As early as 1896 John C. Zimmerman, with help from his wife and four children, built their second hotel, the Keystone. Most of the construction on the three-story, forty-room building, including brickmaking, was done by hand.
Convicts from the state penitentiary in Caon City completed much of the work in the Cache la Poudre and North Park Toll Road. In 1917 the Rocky Mountain News credited convicts working in the Poudre Canyon with having completed the most difficult work out of some 145 miles constructed within the state of Colorado.
By the 1870s, boom towns Lulu and Teller City, just west of bustling Fort Collins, were established and silver excitement was in the air. The Cache la Poudre and North Park Toll Road was built to provide smooth passage for trade.

Auto Tourism

By 1927 automobiles could drive the Cameron Pass roas all the way from Fort Collins to Walden — about a hundred miles. Toursim soon became a major industry in the Cache la Poudre corridor, with campgrounds and motor courts lining the valley. Ironically, this influx of people compromised the very attractions — solitude and beauty — that drew visitors in the first place. The paradox climaxed in the early 1970s, when developers proposed a ski area atop Cameron Pass to lure the Winter Olympics to Colorado. Local residents joined environmentalists from across the state to defeat the idea, but one element of the plan survived — an asphalt surface for unpaved Highway 14. That brought still more traffic, helping the economy but applying more pressure on the wilderness. The same trade-off confronts communities throughout Colorado, representing one of the biggest challenges of the late twentieth and early twenty-first centuries.

Forest Conservation

Pingree Park

During the construction of the transcontinental railroad in the late 1860s, the timber fell almost continuously in Pingree Park. Named for the legendary tie-hack George Pingree (who supposedly could cut a hundred ties a day), the tree-covered valley about seventeen miles east of here supplied the Union Pacific with much of its building material. Overcutting decimated the forests, and the site lay abandoned from the 1870s until 1912, when the Agricultural College of Colorado (later Colorado State University) acquired the land. The college, ironically, transformed this overused resource into a model of wise environmental management. Pingree Park became an outdoor classroom, anchoring one of the nation's leading natural resource programs. Colorado State produced so many U.S. Forest Service and National Park employees that it was named “the Ranger Factory” — a training ground for latter-day George Pingrees who build forests up rather than chopping them down.
The legendary George Pingree in 1859 — two years before enlisting in the U. S. Army at Central City. After the Sand Creek Massacre in 1864, Pingree served a ten-day sentence at Fort Lyon for scalping thirteen Indians. He resented his sentence and never regretted his part in the massacre.
In October 1986, Congress passed the National Wild and Scenic Rivers Act to protect the few unpolluted, undeveloped rivers in the United States. Since then, over 10,000 river miles have been protected, including seventy-five miles of the Cache la Poudre — the only Colorado river pristine enough to allow designation.
Right: Grand Ditch construction camp, Hitchen's Gulch, 1942. Begun in the early 1900s, the Grand Ditch was among the first transmountain diversion structures built in the state. There are eight such structures carrying water from other river basins to the Poudre River to supplement it during warm summer months.
Tie-hacks were paid to cents per tie, and could usually cut thirty to forty a day. Legend has it that George Pingree, standing over six feet tall and weighing 225 pounds, could cut one hundred a day.

Irrigation

Farmers have been tapping the Cache la Poudre for irrigation since the early 1870s — and Colorado's government has been regulating the river almost as long. Because water is so scarce in Colorado, state legislators created a network of water districts in 1876 to ensure fair distribution among the various claimants. Since then, the system — based on the doctrine of prior appropriation, which gives top priority to the oldest claims — has governed water use throughout Colorado. By the mid-twentieth century, however, the nature of water regulation changed, with irrigation needs balanced against environmental, aesthetic, and recreational concerns. In October 1986, the federal government set aside seventy-five miles of the Cache la Poudre as a Wild and Scenic River, the only Colorado river so designated.

Portal Rehabilitation Project.

The Pennsylvania Mine drains heavy metal laden water into Peru Creek, a tributary of the Snake River, and results in one of the most significant single loading sources contributing to water quality degradation. The mine is developed on six different “levels,” designated A through F, with A being the highest in elevation and F at the bottom.
The first goal of the project is to establish safe access to the underground workings on both Level F and Level C of the Pennsylvania Mine. Following conplretion of the project, underground investigations will be conducted to provide a more comprehensive understanding of mine hydrology and eventual remedy selection.
Project managed and developed by: Colorado Division of Reclamation Mining & Safety.

It had to do with an employee of the Aspen Welcome Center yelling at me that I was going to get a ticket if I parked there more than 15 minutes from the moment that I drove into the lot. Some spots were signed for 15 minutes; others including one I chose were not. Helpfully the employee called the meter maid to explain to me that the 15 minute rule applied to all spots in the lot regardless of signage or lack thereof. When we left at about the 20-25 minute mark, the other eight cars in the lot had not moved nor were they ticketed.

Camp Hale

Camp Hale, between Red Cliff and Leadville in the Eagle River valley in Colorado, was a U.S. Army training facility constructed in 1942 for what became the 10th Mountain Division. It was named for General Irving Hale and was at an elevation of 9,200 feet (2,800 m) above sea level. Onslow S. Rolfe, who had developed mountain warfare techniques as commander of the 87th Mountain Infantry Regiment, was selected to command Camp Hale. Alpine and Nordic skiing, cold-weather survival as well as various weapons and ordnance. When it was in full operation, approximately 15,000 soldiers were housed there.

Water Street in Red Cliff
Red Cliff is off of US Highway 24 to the east. The town is a former mining camp situated in the canyon of the upper Eagle River just off U.S. Highway 24 north of Tennessee Pass. It was founded in 1879 during the Colorado Silver Boom by miners from Leadville who came over Tennessee Pass scouting for better prospects. The name derives from the red quartzite cliffs surrounding the town. As the first community in the Eagle Valley, it served temporarily as the first county seat of Eagle County.

Minturn was developed primarily as a railroad town in the late 1800s. The Rio Grande railroad line extended across the state of Colorado and Minturn was an important railroad division point. Railroad workers from around the country settled in Minturn, where they installed extra engines in railroad cars for more power over steep mountain passes.

Five and 6 foot widths were common, and the widest place was 9 feet on the straight and level. Turns, though were a different matter. Curves were typically 11 feet wide on the upper side of the curve, with an additional 3 feet of cut bank above that. At the former trail junction, the crossbucks have been moved and the old trail is on common use by both foot traffic and bicycles.

Guernsey Ruts

Oregon Trail Ruts State Historic Site is a preserved site of wagon ruts of the Oregon Trail on the North Platte River, about 0.5 miles south of Guernsey, Wyoming. The Oregon Trail here was winding up towards South Pass. Wagon wheels, draft animals, and people wore down the trail about two to six feet into a sandstone ridge here, during its heavy usage from 18411869. The half-mile stretch is "unsurpassed" and is the best-preserved set of Oregon Trail ruts anywhere along its former length.

The Panama Hotel is known for the rich Japanese American history before and during World War II. The hotel is known for housing the belongings of the Japanese families in Seattle once Executive Order 9066 was enacted and the evacuation of Japanese to internment camps. After the Japanese American internment, most of the Seattle-based families were not able to return due to death, financial constraints, and relocation; their belongings still reside in the basement of the hotel. It is also known as being the namesake of the novel Hotel on the Corner of Bitter and Sweet by Jamie Ford (WikiPedia).

Mount Moran

Mount Moran reflects all the geologic forces shaping the Teton Range. Formed of a massive block of metamorphic gneiss; cut by dikes of igneous granite and diabase; capped by sedimentary sandstone; and flanked by glaciers, this formidible peak dominates the park's northern skyline.
The gneiss and granite are among the oldest rocks in North America, 2.7 and 2.5 billion years old respectively. These resistant rocks form the core of the Teton Range. The vertical “Black Dike” of 775 million year old diabse is about 150 feet wide and jut from the mountain's face because the surrounding gneiss has eroded away.
Five glaciers — Falling Ice, Skillet and Triple — flank Mount MOran. These glaciers formed during a cool period called the Little Ica Age that ended around 1850 AD. Over the past 40 years, the park's glaciers have shrunk by more than 20 percent due to our changing climate.
Tan sandstone caps the summit of this massive peak the remnant of a 510 million year-old beach that stretched for hundreds of miles north and south of here. Sandstone overlies the Black Dike and other ancient igneous and metamorphic rocks.

Lander Cut-Off on the Oregon Trail

In 1858, this ancient path, which had been used by Indians, explorers and mountain men as a shortcut to the Snake River country was developed by Frederick Lander into an alternate route on the Oregon Trail. What is commonly called the Lander Trail or Lander Cut-off starts 9 miles to the southeast at Burnt Ranch (directly behind this sign), crosses the Sweetwater River 6 miles to the northwest, and continues along Lander Creek for 13 miles to the Continental Divide at Little Sandy Creek, the headwaters of the Pacific Ocean. From there it travels west across the Green River Valley, the Wyoming Range, and the Salt River Range before entering present-day Idaho. The Cut-Off rejoins the original Oregon Trail near Fort Hall.
This wagon road was favored by travelers for many reasons. The cut-off saved as much as 7 days travel compared to the old route through Fort Bridger, avoided the expensive ferries across the Green River to the south, and bypassed the 50-mile waterless desert of the Sublette Cut-Off. Its longest waterless section was only 10 miles, and it had access to abundant grass and firewood. The Lander Cut-Off was used by an estimated 13,000 emigrants its first year, with 9,000 of them signing a statement of support for the road at Fort Hall. While use dwindled after the completion of the trans-continental railroad in 1869, the trail was still used by emigrants into the 20th century and played a role in the settlement of the Upper Green River Valley.

South Pass

South Pass was discovered in 1812 by a small party of Astorians led by Robert Stuart as they traveled east with dispatches for John Jacob Astor. It was “rediscovered” in 1824 by a party led by Jedediah Smith as they searched for a winter crossing through the Wind River Mountain Range. William Sublette led a small caravan of wagons to South Pass in 1828. While the party did not take the wagons over the pass, they proved that wagon travel was possible.
Captain Benjamin Bonneville took the first wagons over South Pass into the Green River Basin in 1832. But it wa Lt. John Charles Fremont who would be credited with widely publicizing the route over South Pass as a result of his expedition in 1842. Scattered references to the easy passage over the Rocky Mountains has appeared in newspapers for a decade, but Fremont ignited enthusiasm for South Pass by explaining that a traveler could go th[r]ough the pass without any “toilsome ascents.”
With the discovery of South Pass, the great western migration began. Thousands of Mormons, future Oregonians and Californians would use the trail in the following twenty years.

Oregon Buttes

To the south stand the Oregon Buttes, a major trail landmark. The name is significant because the Buttes were roughly the beginning of the Oregon Territory and also helped keep emigrants encouraged, even though there were still hundreds of miles of rough going ahead. Today, the Oregon Buttes are an Area of Critical Environmental Concern because of their cultural significance and important wildlife values.
About twelve miles to the soutwest of Oregon Buttes is the Tri-Territory site. This site is the location where the Oregon Territory, Mexican Territory, and Louisiana Purchase has a common boundary. The large landmark, just to the south of w[h]ere you are standing, is Pacific Butte. The great height and mass of the butte, combined with a ridge to the north paralleling the emigrant trails, helps to create a visual channel through which travelers migrated on their way through South Pass.
