History Of Rocky Mountain National Park
History of Rocky Mountain National Park began when Paleo-Indians traveled along what is now Trail Ridge Road to hunt and forage for food. Ute and Arapaho people subsequently hunted and camped in the area. In 1820, the Long Expedition, led by Stephen H. Long for whom Longs Peak was named, approached the Rockies via the Platte River. Settlers began arriving in the mid-1800s, displacing the Native Americans who mostly left the area voluntarily by 1860, while others were removed to reservations by 1878. Lulu City, Dutchtown, and Gaskill in the Never Summer Mountains were established in the 1870s when prospectors came in search of gold and silver. The boom ended by 1883 with miners deserting their claims. The railroad reached Lyons, Colorado in 1881 and the Big Thompson Canyon Road—a section of U.S. Route 34 from Loveland to Estes Park—was completed in 1904. The 1920s saw a boom in building lodges and roads in the park, culminating with the construction of Trail Ridge Roa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocky Mountain National Park
Rocky Mountain National Park is an American national park located approximately northwest of Denver in north-central Colorado, within the Front Range of the Rocky Mountains. The park is situated between the towns of Estes Park to the east and Grand Lake to the west. The eastern and western slopes of the Continental Divide run directly through the center of the park with the headwaters of the Colorado River located in the park's northwestern region. The main features of the park include mountains, alpine lakes and a wide variety of wildlife within various climates and environments, from wooded forests to mountain tundra. The Rocky Mountain National Park Act was signed by President Woodrow Wilson on January 26, 1915, establishing the park boundaries and protecting the area for future generations. The Civilian Conservation Corps built the main automobile route, Trail Ridge Road, in the 1930s. In 1976, UNESCO designated the park as one of the first World Biosphere Reserves. In 20 ...

Grand Lake, Colorado
The Town of Grand Lake is a statutory town located in Grand County, Colorado, United States. The town population was 410 at the 2020 United States Census. History Established in 1881, Grand Lake sits at an elevation of and derives its name from the lake on whose shores it is situated: Grand Lake, the largest natural body of water in Colorado. The town of Grand Lake was originally an outfitting and supply point for the mining settlements of Lulu City, Teller City, and Gaskill, but today is a tourist destination adjacent to the western entrance to Rocky Mountain National Park, which surrounds the lake and the town on three sides. Grand Lake was the Grand County seat of government from 1882 to 1888. It was incorporated on June 23, 1944. The Kauffman House is an NRHP-listed rustic log house that functioned as a hotel from its construction in 1892 until 1946. The Grand Lake Area Historical Society purchased the house in 1973 and converted it into a museum as the only pre-20th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Folsom Point
Folsom points are projectile points associated with the Folsom tradition of North America. The style of tool-making was named after the Folsom site located in Folsom, New Mexico, where the first sample was found in 1908 by George McJunkin within the bone structure of a bison, an animal hunted by the Folsom people in New Mexico. The Folsom point was identified as a unique style of projectile point in 1926. Description The points are bifacially worked and have a symmetrical, leaf-like shape with a concave base and wide, shallow grooves running almost the entire length of the point. The edges are finely worked. The characteristic groove, known as fluting, may have served to aid hafting to a wooden shaft or dart. Use-wear studies have shown that some examples were used as knives as well as projectile points. The fluting required great technical ability to effect, and it took archaeologists many years of experimentation to replicate it. This point is thought to be the pinnacle of ...

Bison Antiquus
''Bison antiquus'', the antique bison or ancient bison, is an extinct species of bison that lived in Late Pleistocene North America until around 10,000 years ago. It was one of the most common large herbivores on the North American continent during the late Pleistocene, and is a direct ancestor of the living American bison along with ''Bison occidentalis''.C. G Van Zyll de Jong , 1986, A systematic study of recent bison, with particular consideration of the wood bison (Bison bison athabascae Rhoads 1898), p.53, National Museum of Natural Sciences History The first described remains of ''Bison antiquus'' were collected at Big Bone Lick, Kentucky in Pleistocene deposits in the 1850s and only consisted of a fragmentary posterior skull and a nearly complete horn core. The fossil ( ANSP 12990) was briefly described by Joseph Leidy in 1852. Although the original fossils were fragmentary, a complete skull of an old male was discovered in southern California and were described as a ...

Mammoth
A mammoth is any species of the extinct elephantid genus ''Mammuthus'', one of the many genera that make up the order of trunked mammals called proboscideans. The various species of mammoth were commonly equipped with long, curved tusks and, in northern species, a covering of long hair. They lived from the Pliocene epoch (from around 5 million years ago) into the Holocene at about 4,000 years ago, and various species existed in Africa, Europe, Asia, and North America. They were members of the family Elephantidae, which also contains the two genera of modern elephants and their ancestors. Mammoths are more closely related to living Asian elephants than African elephants. The oldest representative of ''Mammuthus'', the South African mammoth (''M. subplanifrons''), appeared around 5 million years ago during the early Pliocene in what is now southern and eastern Africa. Descendant species of these mammoths moved north and continued to propagate into numerous subsequent spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Projectile Point
In North American archaeological terminology, a projectile point is an object that was hafted to a weapon that was capable of being thrown or projected, such as a javelin, dart, or arrow. They are thus different from weapons presumed to have been kept in the hand, such as knives, spears, axes, hammers, and maces. Stone tools, including projectile points, can survive for long periods, were often lost or discarded, and are relatively plentiful, especially at archaeological sites. They provide useful clues to the human past, including prehistoric trade. A distinctive form of point, identified though lithic analysis of the way it was made, is often a key diagnostic factor in identifying an archaeological industry or culture. Scientific techniques exist to track the specific kinds of rock or minerals that were used to make stone tools in various regions back to their original sources. As well as stone, projectile points were also made of worked wood, bone, antler, horn, or ivory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dent Site
The Dent site is a Clovis culture (about 11,000 years before present) site located in Weld County, Colorado, near Milliken, Colorado. It provided evidence that humans and mammoths co-existed in the Americas. The site is located on an alluvial fan alongside the South Platte River.Hoppe, Kathryn A(2004). "Late Pleistocene mammoth herd structure, migration patterns, and Clovis hunting strategies inferred from isotopic analyses of multiple death assemblages." ''Paleobiology.'' 30(1):135. On p.7 of the pdf file. Discovery Following a period of heavy rainfall and flooding in August 27th 1908, George Mcjunkin, a black cowboy, discovered large animal bones that were exposed near a ranch located in Folsom New Mexico. Because of Mcjunkin's major contribution to American history he received his spot in the Hall of Great Westerners, managed by The National Cowboy and Western Heritage Museum Shortly after Mcjunkin's death in 1922 and well after his discovery in 1908, his reports of the large ...
