Navajo State Park
Navajo State Park is a state park of Colorado, USA, on the north shore of Navajo Lake. Touted as Colorado's answer to Lake Powell, this reservoir on the San Juan River begins in Colorado's San Juan Mountains and extends into New Mexico. Its area is , and it has of shoreline in two states. Park activities include boating, houseboating, fishing, camping, and wildlife viewing. There is a New Mexico state park at the southern end of the lake. History The area where Navajo State Park now sits was originally inhabited by the Ancestral Puebloans who abandoned the area around 1050 A.D. because of a serious drought at that time. The Ute and Navajo tribes settled the area during the 14th century. The 10 explorers of the Dominguez–Escalante Expedition were some of the first white men entering the area. Their mission was to create a route from New Mexico to California for the Spaniards. In the early 1880s, the Denver and Rio Grande Western Railroad laid their tracks in the are ...

Navajo People
The Navajo (; British English: Navaho; nv, Diné or ') are a Native American people of the Southwestern United States. With more than 399,494 enrolled tribal members , the Navajo Nation is the largest federally recognized tribe in the United States; additionally, the Navajo Nation has the largest reservation in the country. The reservation straddles the Four Corners region and covers more than 27,325 square miles (70,000 square km) of land in Arizona, Utah, and New Mexico. The Navajo Reservation is slightly larger than the state of West Virginia. The Navajo language is spoken throughout the region, and most Navajos also speak English. The states with the largest Navajo populations are Arizona (140,263) and New Mexico (108,306). More than three-fourths of the enrolled Navajo population resides in these two states.

Surficial Geology
Superficial deposits (or surficial deposits) refer to geological deposits typically of Quaternary age (less than 2.6 million years old). These geologically recent unconsolidated sediments may include stream channel and floodplain deposits, beach sands, talus gravels and glacial drift and moraine. All pre-Quaternary deposits are referred to as bedrock. Types and history There are several types of superficial deposit, including raised beaches and brickearth. These were formed in periods of climate change during the ice ages. The raised beaches were generally formed during periods of higher sea level, when ice sheets were at a minimum, and the sand and shingle deposits can be seen in many low cliffs. The brickearth is originally a wind-blown dust deposited under extremely cold, dry conditions but much has been re-deposited by flood water and mixed with flints. Superficial deposits were originally recorded only onshore and around the coast where they were laid down by various natu ...

Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today, although a third epoch, the Anthropocene, has been proposed but is not yet officially recognised by the ICS). The Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive formations or "orders" ( it, quattro ordini). The term "quaternary" was introduced by Jules Desnoye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...

Tertiary
Tertiary ( ) is a widely used but obsolete term for the geologic period from 66 million to 2.6 million years ago. The period began with the demise of the non-avian dinosaurs in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic Era, and extended to the beginning of the Quaternary glaciation at the end of the Pliocene Epoch. The time span covered by the Tertiary has no exact equivalent in the current geologic time system, but it is essentially the merged Paleogene and Neogene periods, which are informally called the Early Tertiary and the Late Tertiary, respectively. The Tertiary established the Antarctic as an icy island continent. Historical use of the term The term Tertiary was first used by Giovanni Arduino during the mid-18th century. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy. Later a fourth period, the Quaternary, was applied. In the early d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piedra River (Colorado)
The Piedra River (also known as El Rio De La Piedra Parada, Pedra, Rio, and Rio Piedre) is a river in the U.S. state of Colorado. It drains parts of Archuleta, Hinsdale, and Mineral counties along a mainstem length of about . The river flows through a series of isolated box canyons, emptying into the San Juan River at Navajo Lake. Its name stems from the Spanish word, ''piedra'', meaning ''rock''. Course The Piedra River is formed by the confluence of its East Fork and Middle Fork, deep in the San Juan Mountains. The Middle Fork, larger of the two, rises in a bowl-shaped valley in the San Juan National Forest. It flows southwards, and forms the Piedra after a journey of . The East Fork starts at a small unnamed lake in the Rio Grande National Forest and flows southwest for about . The Piedra flows through open meadows, then drops into a canyon, receiving O'Neal Creek from the left and Williams, Weimuche and Sand Creeks from the right. The river angles to the southwest and rece ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesic Habitat
In ecology, a mesic habitat is a type of habitat with a moderate or well-balanced supply of moisture, e.g., a mesic forest, a temperate hardwood forest, or dry-mesic prairie. Mesic habitats transition to xeric shrublands in a non-linear fashion, which is evidence of a threshold. Mesic is one of a triad of terms used to describe the amount of water in a habitat. The others are xeric and hydric. Further examples of mesic habitats include streamsides, wet meadows, springs, seeps, irrigated fields, and high elevation habitats. These habitats effectively provide drought insurance as land at higher elevations warms due to seasonal or other change. Healthy mesic habitats act like sponges in that they store water in such a way that it can be deposited to neighboring habitats as needed. They are common in dryer regions of the western United States, and can be a good water source to neighboring desert habitats. Healthy mesic habitats also provide forb and insects for organisms belonging t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Navajo Nation
The Navajo Nation ( nv, Naabeehó Bináhásdzo), also known as Navajoland, is a Native American reservation in the United States. It occupies portions of northeastern Arizona, northwestern New Mexico, and southeastern Utah; at roughly , the Navajo Nation is the largest land area held by a Native American tribe in the U.S., exceeding ten U.S. states. In 2010, the reservation was home to 173,667 out of 332,129 Navajo tribal members; the remaining 158,462 tribal members lived outside the reservation, in urban areas (26 percent), border towns (10 percent), and elsewhere in the U.S. (17 percent). The seat of government is located in Window Rock, Arizona. The United States gained ownership of this territory in 1848 after acquiring it in the Mexican-American War. The reservation was within New Mexico Territory and straddled what became the Arizona-New Mexico border in 1912, when the states were admitted to the union. Unlike many reservations, it has expanded several times since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Navajo Dam
Navajo Dam is a dam on the San Juan River (Colorado River), San Juan River, a tributary of the Colorado River, in northwestern New Mexico in the United States. The high earthen dam is situated in the foothills of the San Juan Mountains about upstream and east of Farmington, New Mexico. It was built by the U.S. Bureau of Reclamation (Reclamation) in the 1960s to provide flood control, irrigation, domestic and industrial water supply, and storage for droughts. A small hydroelectric power plant was added in the 1980s. The dam is a major feature of the Colorado River Storage Project, which is designed to regulate water resources across the entire Upper Colorado River Basin. The reservoir, Navajo Lake, is a popular recreation area and one of the largest bodies of water in New Mexico, with its upper portion extending into Colorado. Specifications Navajo is a rolled earthfill embankment dam, composed of three "zones" of alternating cobbles, gravel, sand and clay. The dam is high and ...
