Mesa De Maya
The Mesa de Maya is a prominent volcanic tableland rising to above the Great Plains in southeastern Colorado. A narrow finger of the mesa extends eastward through the northeastern corner of New Mexico and a few miles into Oklahoma where it is known as the Black Mesa. The elevation of the Mesa de Maya ranges from at its easternmost extension to in the west. The high mesas eastward from Raton, New Mexico and Trinidad, Colorado are sometimes collectively called the Mesa de Maya, Raton Mesas, or the Raton mesa region. All the mesas are volcanic in origin caused by lava flows which solidified into basalt. Over time the softer sedimentary rock surrounding the basalt eroded leaving several distinct large elevated tablelands with precipitous sides which include the Mesa de Maya. Description Mesa de Maya originated from a basaltic lava flow 180 million years ago. Originating in Colorado at a place named Piney Mountain, the lava flow measures 55 miles long, from one-half (1 km) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesa De Maya, Colorado
A mesa is an isolated, flat-topped elevation, ridge, or hill, bounded from all sides by steep escarpments and standing distinctly above a surrounding plain. Mesas consist of flat-lying soft sedimentary rocks, such as shales, capped by a resistant layer of harder rock, like sandstone or limestone, forming a caprock that protects the flat summit. The caprock may also include dissected lava flows or eroded duricrust. Unlike a ''plateau'', which is a broader, elevated region that may not have horizontal bedrock (e.g., Tibetan Plateau), a mesa is defined by flat-lying strata and steep-sided isolation. Large, flat-topped plateaus with horizontal strata, less isolated and often part of extensive plateau systems, are called '' tablelands''. A ''butte'' is a smaller, eroded mesa with a limited summit, while a ''cuesta'' has a gentle dip slope and one steep escarpment due to tilted strata.Duszyński, F., Migoń, P. and Strzelecki, M.C., 2019.

Ponderosa Pine
''Pinus ponderosa'', commonly known as the ponderosa pine, bull pine, blackjack pine, western yellow-pine, or filipinus pine, is a very large pine tree species of variable habitat native to mountainous regions of western North America. It is the most widely distributed pine species in North America.Safford, H.D. 2013. Natural Range of Variation (NRV) for yellow pine and mixed conifer forests in the bioregional assessment area, including the Sierra Nevada, southern Cascades, and Modoc and Inyo National Forests. Unpublished report. USDA Forest Service, Pacific Southwest Region, Vallejo, CA/ref> ''Pinus ponderosa'' grows in various erect forms from British Columbia southward and eastward through 16 western U.S. states and has been introduced in temperate regions of Europe and in New Zealand. It was first documented in modern science in 1826 in eastern Washington near present-day Spokane (of which it is the official city tree). On that occasion, David Douglas misidentified it a ...

Piñon Canyon Maneuver Site
The Piñon Canyon Maneuver Site (also Pinon and Pinyon) is a 235,896 acre (955 km2) U.S. Army base in southeastern Colorado. The Piñon Canyon Maneuver Site (PCMS) is a training site for Fort Carson. In 2003, the U.S. Army announced a plan to expand PCMS by purchasing additional land mostly owned by individuals devoted to ranching. Local residents and conservation organizations opposed the expansion. In 2013 the Army cancelled the planned expansion. Setting PCMS is located northeast of Trinidad, Colorado, and is part of Las Animas County, Colorado. It borders on Comanche National Grassland to its north. The Purgatoire River, locally known as the Picketwire, is its eastern boundary. Elevations on Site range from 4,300 to 5,800 feet (1,311 to 1,768 m) The Site has a semi-arid, steppe climate. Annual precipitation is 12 to 16 inches (305–406 mm). The terrain of PCMS is flat to rolling and dotted with small, rocky hills and mesas. The Purgatoire ...

Golden Eagles
The golden eagle (''Aquila chrysaetos'') is a bird of prey living in the Northern Hemisphere. It is the most widely distributed species of eagle. Like all eagles, it belongs to the family Accipitridae. They are one of the best-known birds of prey in the Northern Hemisphere. These birds are dark brown, with lighter golden-brown plumage on their napes. Immature eagles of this species typically have white on the tail and often have white markings on the wings. Golden eagles use their agility and speed combined with powerful feet and large, sharp talons to hunt a variety of prey, mainly hares, rabbits, and marmots and other ground squirrels. Golden eagles maintain home ranges or territories that may be as large as . They build large nests in cliffs and other high places to which they may return for several breeding years. Most breeding activities take place in the spring; they are monogamous and may remain together for several years or possibly for life. Females lay up to four eg ...

Pronghorn
The pronghorn (, ) (''Antilocapra americana'') is a species of artiodactyl (even-toed, hoofed) mammal indigenous to interior western and central North America. Though not an antelope, it is known colloquially in North America as the American antelope, prong buck, pronghorn antelope, and prairie antelope, because it closely resembles the antelopes of the Old World and fills a similar ecological niche due to parallel evolution. It is the only surviving member of the family Antilocapridae. During the Pleistocene epoch, about 11 other antilocaprid species existed in North America, many with long or spectacularly twisted horns.Smithsonian Institution. North American MammalsPronghorn ''Antilocapra americana'' Three other genera ('' Capromeryx'', '' Stockoceros'' and '' Tetrameryx'') existed when humans entered North America but are now extinct. The pronghorn's closest living relatives are the giraffe and okapi. See Fig. S10 in Supplementary Information. The antilocaprids are part of ...

A pair of horns may weigh up to ; the sheep typically weigh up to . Recent genetic testing indicates three distinct subspecies of ''Ovis canadensis'', one of which is endangered: Sierra Nevada bighorn sheep, ''O. c. sierrae''. Sheep originally crossed to North America over the Beringia, Bering Land Bridge from Siberia; the population in North America peaked in the millions, and the bighorn sheep entered into the mythology of Indigenous peoples of the Americas, Native Americans. By 1900, the population had crashed to several thousand due to diseases introduced through European livestock and overhunting. Taxonomy and genetics ''Ovis canadensis'' is one of two species of mountain Ovis, sheep in North America; the other species being ''O. dalli'', the Dall sheep.

American Black Bear
The American black bear (''Ursus americanus''), or simply black bear, is a species of medium-sized bear which is Endemism, endemic to North America. It is the continent's smallest and most widely distributed bear species. It is an omnivore, with a diet varying greatly depending on season and location. It typically lives in largely forested areas; it will leave forests in search of food and is sometimes attracted to human communities due to the immediate availability of food. The International Union for Conservation of Nature (IUCN) lists the American black bear as a least-concern species because of its widespread distribution and a large population, estimated to be twice that of all other bear species combined. Along with the brown bear (''Ursus arctos''), it is one of the two modern bear species not considered by the IUCN to be globally threatened with extinction. Taxonomy and evolution The American black bear is not closely related to the brown bear or polar bear, though all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mule Deer
The mule deer (''Odocoileus hemionus'') is a deer indigenous to western North America; it is named for its ears, which are large like those of the mule. Two subspecies of mule deer are grouped into the black-tailed deer. Unlike the related white-tailed deer (''Odocoileus virginianus''), which is found throughout most of North America east of the Rocky Mountains and in the valleys of the Rocky Mountains from Idaho and Wyoming northward, mule deer are found only on the western Great Plains, in the Rocky Mountains, in the southwest United States, and on the west coast of North America. Mule deer have also been introduced to Argentina and Kauai, Kauai, Hawaii. Taxonomy Mule deer can be divided into two main groups: the mule deer (''sensu stricto'') and the black-tailed deer. The first group includes all subspecies, except ''O. h. columbianus'' and ''Sitka deer, O. h. sitkensis'', which are in the black-tailed deer group. The two main groups have been treated as separate species, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
