Colorado History Chronology
Colorado History Chronology 13,000 B.C. Big game hunters may have occupied area later known as Colorado. Evidence shows that they were here by at least 9200 B.C. A.D. 1 to 1299 A.D. Advent of great Prehistoric Cliff Dwelling Civilization in the Mesa Verde region. 1276 to 1299 A.D. A great drought and/or pressure from nomadic tribes forced the Cliff Dwellers to abandon their Mesa Verde homes. 1500 A.D. Ute Indians inhabit mountain areas of southern Rocky Mountains making these Native Americans the oldest continuous residents of Colorado. 1541 A.D. Coronado, famed Spanish explorer, may have crossed the southeastern corner of present Colorado on his return march to Mexico after vain hunt for the golden Seven Cities of Cibola. 1682 A.D. Explorer La Salle appropriates for France all of the area now known as Colorado east of the Rocky Mountains. 1765 A.D. Juan Maria Rivera leads Spanish expedition into San Juan and Sangre de Cristo Mountains in search of gold and silver. 1776 A.D. Friars Escalante and Dominguez seeking route from Santa Fe to California missions, traverse what is now western Colorado as far north as the White River in Rio Blanco County. 1803 A.D. Through the Louisiana Purchase, signed by President Thomas Jefferson, the United States acquires a vast area which included what is now most of eastern Colorado. While the United States lays claim to this vast territory, Native Americans have resided here for hundreds of years. 1806 A.D. Lieutenant Zebulon M. Pike and small party of U.S. -

PEAK to PRAIRIE: BOTANICAL LANDSCAPES of the PIKES PEAK REGION Tass Kelso Dept of Biology Colorado College 2012

Mt. Olympus, mythological home of the Greek gods, Yosemite’s Half Dome, the ever-classic Matterhorn, Alaska’s Denali, and Colorado’s Pikes Peak all share the quality of compelling attraction that a charismatic alpine profile evokes. At the base of our peak along the confluence of two small, nondescript streams, Native Americans gathered thousands of years ago. Explorers, immigrants, city-visionaries and fortune-seekers arrived successively, all shaping in turn the region and communities that today spread from the flanks of Pikes Peak. From any vantage point along the Interstate 25 corridor, the Colorado plains, or the Arkansas River Valley escarpments, Pikes Peak looms as the dominant feature of a diverse “bioregion”, a geographical area with a distinct flora and fauna, that stretches from alpine tundra to desert grasslands. “Biodiversity” is shorthand for biological diversity: a term covering a broad array of contexts from the genetics of individual organisms to ecosystem interactions. The news tells us daily of ongoing threats from the loss of biodiversity on global and regional levels as humans extend their influence across the face of the earth and into its sustaining processes. On a regional level, biologists look for measures of biodiversity, celebrate when they find sites where those measures are high and mourn when they diminish; conservation organizations and in some cases, legal statutes, try to protect biodiversity, and communities often struggle to balance human needs for social infrastructure with desirable elements of the natural landscape. -
Denudation History and Internal Structure of the Front Range and Wet Mountains, Colorado, Based on Apatite-Fission-Track Thermoc
NEW MEXICO BUREAU OF GEOLOGY & MINERAL RESOURCES, BULLETIN 160, 2004 41 Denudation history and internal structure of the Front Range and Wet Mountains, Colorado, based on apatitefissiontrack thermochronology 1 2 1Department of Earth and Environmental Science, New Mexico Institute of Mining and Technology, Socorro, NM 87801Shari A. Kelley and Charles E. Chapin 2New Mexico Bureau of Geology and Mineral Resources, New Mexico Institute of Mining and Technology, Socorro, NM 87801 Abstract An apatite fissiontrack (AFT) partial annealing zone (PAZ) that developed during Late Cretaceous time provides a structural datum for addressing questions concerning the timing and magnitude of denudation, as well as the structural style of Laramide deformation, in the Front Range and Wet Mountains of Colorado. AFT cooling ages are also used to estimate the magnitude and sense of dis placement across faults and to differentiate between exhumation and faultgenerated topography. AFT ages at low elevationX along the eastern margin of the southern Front Range between Golden and Colorado Springs are from 100 to 270 Ma, and the mean track lengths are short (10–12.5 µm). Old AFT ages (> 100 Ma) are also found along the western margin of the Front Range along the Elkhorn thrust fault. In contrast AFT ages of 45–75 Ma and relatively long mean track lengths (12.5–14 µm) are common in the interior of the range. The AFT ages generally decrease across northwesttrending faults toward the center of the range. The base of a fossil PAZ, which separates AFT cooling ages of 45– 70 Ma at low elevations from AFT ages > 100 Ma at higher elevations, is exposed on the south side of Pikes Peak, on Mt. -

A TIMELINE for GOLDEN, COLORADO (Revised October 2003)
A TIMELINE FOR GOLDEN, COLORADO (Revised October 2003) "When a society or a civilization perishes, one condition can always be found. They forgot where they came from." Carl Sandburg This time-line was originally created by the Golden Historic Preservation Board for the 1995 Golden community meetings concerning growth. It is intended to illustrate some of the events and thoughts that helped shape Golden. Major historical events and common day-to-day happenings that influenced the lives of the people of Golden are included. Corrections, additions, and suggestions are welcome and may be relayed to either the Historic Preservation Board or the Planning Department at 384-8097. The information concerning events in Golden was gathered from a variety of sources.

Shannon Isochron/West, Bulletin of Isotopic Geochronology, v. 49, pp. 13-20 Downloaded from: https://geoinfo.nmt.edu/publications/periodicals/isochronwest/home.cfml?Issue=49 Isochron/West was published at irregular intervals from 1971 to 1996. The journal was patterned after the journal Radiocarbon and covered isotopic age-dating (except carbon-14) on rocks and minerals from the Western Hemisphere. Initially, the geographic scope of papers was restricted to the western half of the United States, but was later expanded. The journal was sponsored and staffed by the New Mexico Bureau of Mines (now Geology) & Mineral Resources and the Nevada Bureau of Mines & Geology.

THE COLORADO MAGAZINE Published by the State Historical and Natural History Society of Colorado
THE COLORADO MAGAZINE Published by The State Historical and Natural History Society of Colorado VOL. Ill Denver Colorado, August, 1926 NO. 3 The Colorado Constitution By Henry J. Hersey (Formerly Judge of the District Court of Denver) Colorado's admission to the Union is not alone significant because it occurred 100 years after the Declaration of Independ ence, but also because the efforts for governmental independence were accompanied by heroic and almost revolutionary (though peaceful) acts. The early settlers and gold seekers of 1858 found themselves in a country which the various explorers had reported as a barren desert and worthless for human habitation ; though nominally a part of the Territory of Kansas, yet it was so remote, because of the slow means of transportation and communication, that it was outside the pale of governmental consideration or interest, and the pioneers were forced by existing conditions to establish some sort of a government, provide courts and make laws for themselves. So on the plains we find them quickly creating the People's Courts by the methods of pure democracies, assemblies of the peo ple hurriedly called together and accused persons brought before them and tried before a judge selected from the people, the people themselves acting as a jury ;1 in the mountains a civil, rather than a criminal, court was the need of the hour and the Miners' Court was created, having, however, both civil and criminal jurisdiction. The Miners' Court was also established by the mass meeting meth ods used in the ancient, pure democracies, for representative or republican form of government is always a matter of growth and later development. -
