Bechan Cave
Bechan Cave is a single-room sandstone rock shelter located at an elevation of along Bowns Canyon Creek, a tributary of the Glen Canyon segment of the Colorado River, in Kane County in southeastern Utah in the United States. The cave is roughly wide, high and deep. It has a single entrance that faces southwest and is well-lit during the daytime. The cave holds alluvial deposits containing the remains of Pleistocene megafauna, including mammoths, ground sloths, and even-toed ungulates. Archaeological excavation of the site in 1983 and 1984 by paleontologists Larry Agenboard and Jim Mead unearthed animal bones, dung, hair, and teeth dating from 11,555 BCE to 9720 BCE, underneath "a few feet" of cave fill, consisting of ceiling spall and wind-blown sand, containing evidence of Holocene habitation from the Archaic period to the Basketmaker culture and possibly even by Navajo or Paiute. Among the items unearthed were large dung boluses, similar in size to the dung of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kane County, Utah
Kane County is a county in the U.S. state of Utah. As of the 2010 United States Census, the population was 7,125. Its county seat and largest city is Kanab. History The county was created on January 16, 1864, by the Utah Territory legislature, with areas partitioned from Washington County. It was named for Col. Thomas L. Kane, a friend of the Latter Day Saint settlers in the 1840s and 1850s. The county boundary was adjusted in 1869, when a portion was returned to Washington County; in 1880, when San Juan County was created; and in 1883, when portions were partitioned from Kane and added to Iron and Washington counties. Geography Kane County lies on the south line of the state of Utah. Its south border abuts the northern border of the state of Arizona. The Colorado River, reformed as Lake Powell, forms its eastern border. Grand Staircase–Escalante National Monument covers much of the county. A rugged and inhospitable country of deserts, mountains, and cliffs make up the ter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Spruce
The blue spruce (''Picea pungens''), also commonly known as green spruce, Colorado spruce, or Colorado blue spruce, is a species of spruce tree. It is native to North America, and is found in USDA growing zones 1 through 7. It is found naturally in Arizona, Colorado, Idaho, New Mexico, Utah and Wyoming. It has been widely introduced elsewhere and is used as an ornamental tree in many places far beyond its native range. The blue spruce has blue-green colored needles and is a coniferous tree. Description In the wild, ''Picea pungens'' grows to about , but when planted in parks and gardens it seldom exceeds tall by wide. The tree can grow larger if the tip is cut when it is at least 3 years old. It is a columnar or conical evergreen conifer with densely growing horizontal branches. It has scaly grey bark on the trunk with yellowish-brown branches. Waxy gray-green leaves, up to long, are arranged radially on the shoots which curve upwards. The pale brown cones are up to long. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Navajo Language
Navajo or Navaho (; Navajo: or ) is a Southern Athabaskan language of the Na-Dené family, through which it is related to languages spoken across the western areas of North America. Navajo is spoken primarily in the Southwestern United States, especially on the Navajo Nation. It is one of the most widely spoken Native American languages and is the most widely spoken north of the Mexico–United States border, with almost 170,000 Americans speaking Navajo at home as of 2011. The language has struggled to keep a healthy speaker base, although this problem has been alleviated to some extent by extensive education programs in the Navajo Nation, including the creation of versions of the films Finding Nemo and Star Wars dubbed into Navajo. The United States in World War II used the Navajo language to develop a system of code talkers to relay messages that could not be cracked. Navajo has a fairly large phoneme inventory, including several uncommon consonants that are not found in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southwestern Archaeology
Southwestern archaeology is a branch of archaeology concerned with the Southwestern United States and Northwestern Mexico. This region was first occupied by hunter-gatherers, and thousands of years later by advanced civilizations, such as the Ancestral Puebloans, the Hohokam, and the Mogollon. This area, identified with the current states of Colorado, Arizona, New Mexico, Utah, and Nevada in the western United States, and the states of Sonora and Chihuahua in northern Mexico, has seen successive prehistoric cultural traditions for at least of 12,000 years. An often-quoted statement from Erik Reed (1964) defined the Greater Southwest culture area as extending north to south from Durango, Mexico, to Durango, Colorado, and east to west from Las Vegas, Nevada, to Las Vegas, New Mexico.Cordell, Linda S. and Maxine E. McBrinn 2012 ''Archaeology of the Southwest'', 3rd edition. Left Coast Press, Walnut Creek Differently areas of this region are also known as the American Southwest, Nort ...

Colorado Plateau
The Colorado Plateau, also known as the Colorado Plateau Province, is a physiographic and desert region of the Intermontane Plateaus, roughly centered on the Four Corners region of the southwestern United States. This province covers an area of 336,700 km2 (130,000 mi2) within western Colorado, northwestern New Mexico, southern and eastern Utah, northern Arizona, and a tiny fraction in the extreme southeast of Nevada. About 90% of the area is drained by the Colorado River and its main tributaries: the Green, San Juan, and Little Colorado. Most of the remainder of the plateau is drained by the Rio Grande and its tributaries. The Colorado Plateau is largely made up of high desert, with scattered areas of forests. In the south-west corner of the Colorado Plateau lies the Grand Canyon of the Colorado River. Much of the Plateau's landscape is related to the Grand Canyon in both appearance and geologic history. The nickname "Red Rock Country" suggests the brightly colored ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carex
''Carex'' is a vast genus of more than 2,000 species of grass-like plants in the family Cyperaceae, commonly known as sedges (or seg, in older books). Other members of the family Cyperaceae are also called sedges, however those of genus ''Carex'' may be called true sedges, and it is the most species-rich genus in the family. The study of ''Carex'' is known as caricology. Description All species of ''Carex'' are perennial, although some species, such as '' C. bebbii'' and '' C. viridula'' can fruit in their first year of growth, and may not survive longer. They typically have rhizomes, stolons or short rootstocks, but some species grow in tufts (caespitose). The culm – the flower-bearing stalk – is unbranched and usually erect. It is usually distinctly triangular in section. The leaves of ''Carex'' comprise a blade, which extends away from the stalk, and a sheath, which encloses part of the stalk. The blade is normally long and flat, but may be folded, inrolled, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graminoid
In botany and ecology, graminoid refers to a herbaceous plant with a grass-like morphology, i.e. elongated culms with long, blade-like leaves. They are contrasted to forbs, herbaceous plants without grass-like features. The plants most often referred to include the families Poaceae (grasses in the strict sense), Cyperaceae (sedges), and Juncaceae (rushes). These are not closely related but belong to different clades in the order Poales. The grasses (Poaceae) are by far the largest family with some 12,000 species. Besides their similar morphology, graminoids share the widespread occurrence and often dominance in open habitats such as grasslands or marshes. They can however also be found in the understory of forests. Sedges and rushes tend to prefer wetter habitats than grasses.

Plant Stem
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue. The stem can also be called halm or haulm. The stem is normally divided into nodes and internodes: * The nodes hold one or more leaves, as well as buds which can grow into branches (with leaves, conifer cones, or flowers). Adventitious roots may also be produced from the nodes. * The internodes distance one node from another. The term "shoots" is often confused with "stems"; "shoots" generally refers to new fresh plant growth including both stems and other structures like leaves or flowers. In most plants stems are located above the soil surface but some plants have underground stems. Stems have four main functions which are: * Support for and the elevation of leaves, flowers, and fruits. The stems ke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bolus (digestion)
In digestion, a bolus (from Latin ''bolus'', "ball") is a ball-like mixture of food and saliva that forms in the mouth during the process of chewing (which is largely an adaptation for plant-eating mammals). It has the same color as the food being eaten, and the saliva gives it an alkaline pH. Under normal circumstances, the bolus is swallowed, and travels down the esophagus to the stomach for digestion. See also * Chyme *Chyle Chyle (from the Greek word χυλός ''chylos'', "juice") is a milky bodily fluid consisting of lymph and emulsified fats, or free fatty acids (FFAs). It is formed in the small intestine during digestion of fatty foods, and taken up by lymph v ... References Digestive system {{Digestive-stub ...

Southern Paiute
The Southern Paiute people are a tribe of Native Americans who have lived in the Colorado River basin of southern Nevada, northern Arizona, and southern Utah. Bands of Southern Paiute live in scattered locations throughout this territory and have been granted federal recognition on several reservations. The first European contact with the Southern Paiute occurred in 1776, when fathers Silvestre Vélez de Escalante and Francisco Atanasio Domínguez encountered them during an attempt to find an overland route to the missions of California. They noted that some of the Southern Paiute men "had thick beards and were thought to look more in appearance like Spanish men than native Americans". Before this date, the Southern Paiute suffered slave raids by the Navajo and the Ute. The arrival of Spanish and later Euro-American explorers into their territory increased slave raiding by other tribes. In 1851, Mormon settlers strategically occupied Paiute water sources, which created a depend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
