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.

Tom Schweich 1952. 20-Jun-2018

Coll. No. 1952, 20 June 2018, characters observed: Perennial herb, 40 cm. to 55 cm., glabrous except basal leaves; Stem, single, erect, leafy, glabrous; Leaves, basal and cauline, basal, simple, petiole, 10 mm., transition unclear, blade, 23 mm. × 3 mm. wide, oblanceolate, hairs, dolabriform, cauline, sessile, basally lobed, 0.8-1.5 mm., 23 mm. × 3.5 mm. wide, lanceolate, margin entire; Inflorescence, raceme, 25 mm. × 12.5 mm. wide, elongating in fruit; Flowers, radial; Sepals, #4, 1 row, 5 mm. × 1 mm. wide, elliptic, color green, glabrous; Petals, 9 mm. × 1.8 mm. wide, spoon-shaped, margin entire, color lavender (when dry); Fruit, mature, 60 mm. × 1 mm. wide, appressed to rachis, glabrous.

Arabis drummondii is the correct name for this species in that genus; the epithet stricta has priority in Boechera. This very distinctive species is easily recognized by having basal leaves with branched trichomes, all sessile and 2-rayed (malpighiaceous). It is also the most promiscuous, having formed apomictic hybrids with at least 15 other species of Boechera. (Al-Shebaz, FNANM)

Willow Creek, Jackson County, Colorado. North slope of Rabbit Ears Range, along Willow Creek and Forest Road 106, 7.4 km. north of Haystack Mountain, 6.7 km. south of Rand. 40.3942N, 106.1879W. WGS 1984 Elev. 2750 m. Common, especially along roadsides.

This area extensively collected by J. E. Tear, Jr. (1993-1995, 135 collections, deposited at CS) and B. E. Nelson (2000, 145 collections, deposited at RM).

Tom Schweich 1953. 20-Jun-2018

Coll. No. 1953, 20 June 2018, characters observed: Calyx, tube 2.5-3.0 mm. + lobes 3.5-4.0 mm.; Corolla, filiform, tube 20 mm. × 1 mm. wide flaring gradually to 3 mm. + lobes 7.5-8.0 mm.; Anthers, close to orfice.

Two subspecies of Ipomopsis aggregata (Pursh) V.E. Grant have been collected within ½ km. radius of this collection. J. E. Tear, Jr. #258, 1993-06-16, CS81546, was determined I. a. subsp. weberi V.E. Grant & Wilkin by Ackerfield. Ackerfield (2015) now treats subsp. weberi as a synonym of I. a. subsp. attenuata (A. Gray) V.E. Grant & A.D. Grant. B. E. Nelson #49939, 2000-6-27, RM760254, was determined I. a. subsp. aggregata.

This specimen will key ambiguously to either subsp. attenuata or subsp. aggregata in Ackerfield (2015) depending upon how much weight one places on the shape of the corolla tube vs. the position of the anthers. However, this specimen keys unambiguously to subsp. attenuata in Grant & Wilkin (1986) based upon the shape and dimensions of the corolla tube and the position of the anthers.

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.
