Gypsum Cave
Gypsum Cave is a limestone cave in eastern Clark County, Nevada, United States, about east of Las Vegas, that is listed on the National Register of Historic Places (NRHP). Description The cave contains six rooms and is measured at long by wide. The cave was first documented by Mark Raymond Harrington in a 1930 edition of ''Scientific American''. Up until about 11,000 BC (11,000 radiocarbon years ago), Gypsum Cave was inhabited by the Shasta ground sloth. A few hundreds feet away, the Gypsum Cave Mine contains gypsum, anhydrite and uranium. History Human habitation of the cave dates to around 3000 BC. Harrington provided the first documentation of the contents of the cave following excavation in 1930-1931. Habitation occurred at the same time at other local sites like Tule Springs, Lake Mojave and the Pinto Basin. The skull of the ground sloth ''Nothrotheriops shastensis'' Sinclair was found in Room 3 by the archaeologist Bertha Parker, who was Harrington's niece and se ...

Limestone Cave
A solutional cave, solution cave, or karst cave is a cave usually formed in the soluble rock limestone. It is the most frequently occurring type of cave. It can also form in other rocks, including chalk, dolomite, marble, salt beds, and gypsum. Process Bedrock is dissolved by natural acid in groundwater that seeps through bedding-planes, faults, joints and so on. Over geological epochs these openings expand as the walls are dissolved to become caves or cave systems. The portions of a solutional cave that are below the water table or the local level of the groundwater will be flooded. Limestone caves The largest and most abundant solutional caves are located in limestone. Limestone caves are often adorned with calcium carbonate formations produced through slow precipitation. These include flowstones, stalactites, stalagmites, helictites, soda straws, calcite rafts and columns. These secondary mineral deposits in caves are called ''speleothems''. Carbonic acid dis ...

Pinto Basin
Pinto is a Portuguese, Spanish, Jewish (Sephardic), and Italian surname. It is a high-frequency surname in all Portuguese-speaking countries and is also widely present in Spanish-speaking countries, Italy, India especially in Mangalore, Karnataka France and Israel. Historically, it has been common among political elites in Portuguese- and Spanish-speaking countries, as numerous presidents, prime ministers, and heads of state have shared the surname. In many languages, Pinto means "colored" or "painted" as it derives from the Late Latin and Classical Latin , and in some cases, at least from the same word in the sense "lively or restless person". It is linguistically related to the name of Columbus' ship '' La Pinta'', meaning "The Painted One", "The Look", or "The Spotted One". Also related, though greatly diverging in meaning, is the unit of measurement pint, which comes from the Old French word and perhaps ultimately from Vulgar Latin meaning "painted", for marks painted on t ...

Haringtonhippus
''Haringtonhippus'' is an extinct genus of stilt-legged equine from the Pleistocene of North America The genus is monospecific, consisting of the species ''H. francisci'', initially described in 1915 by Oliver Perry Hay as ''Equus francisci''. Prior to its formal description, it was sometimes referred to as the New World stilt-legged horse. ''Haringtonhippus'' fossils have only been discovered in North America. Specimens have been found from southern Mexico to southern South Dakota and in Alberta, Canada, at sites such as Gypsum Cave and Natural Trap Cave, as well as eastern Beringia in Yukon A later study found that ''Equus cedralensis'' from the Late Pleistocene of Mexico also belonged to this species. The earliest species of the lineage appeared in North America during the Late Pliocene to Early Pleistocene, around 2 to 3 Ma. It became extinct at the end of the Late Pleistocene. Taxonomy ''Haringtonhippus'' is named after Charles Richard Harington. It was originally described ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bureau Of Land Management
The Bureau of Land Management (BLM) is an agency within the United States Department of the Interior responsible for administering federal lands. Headquartered in Washington DC, and with oversight over , it governs one eighth of the country's landmass. President Harry S. Truman created the BLM in 1946 by combining two existing agencies: the General Land Office and the Grazing Service. The agency manages the federal government's nearly of subsurface mineral estate located beneath federal, state and private lands severed from their surface rights by the Homestead Act of 1862. Most BLM public lands are located in these 12 western states: Alaska, Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming. The mission of the BLM is "to sustain the health, diversity, and productivity of the public lands for the use and enjoyment of present and future generations." Originally BLM holdings were described as "land nobody wanted" because home ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ephedra (plant)
''Ephedra'' is a genus of gymnosperm shrubs. The various species of ''Ephedra'' are widespread in many arid regions of the world, ranging across southwestern North America, southern Europe, northern Africa, southwest and central Asia, northern China and western South America. It is the only extant genus in its family, Ephedraceae, and order, Ephedrales, and one of the three living members of the division Gnetophyta alongside ''Gnetum'' and ''Welwitschia.'' In temperate climates, most ''Ephedra'' species grow on shores or in sandy soils with direct sun exposure. Common names in English include joint-pine, jointfir, Mormon-tea or Brigham tea. The Chinese name for ''Ephedra'' species is ''mahuang'' (). ''Ephedra'' is the origin of the name of the stimulant ephedrine, which the plants contain in significant concentration. Description The family Ephedraceae, of which ''Ephedra'' is the only genus, are gymnosperms, and generally shrubs, sometimes clambering vines, and rarely, smal ...

Globemallow
''Sphaeralcea'' is a genus of flowering plants in the mallow family (Malvaceae). There are about 40-60 species, including annuals, perennials, and shrubs. Most originate in the drier regions of North America, with some known from South America. They are commonly known as globemallows, globe mallows, or falsemallows. The name of the genus is derived from the Greek words σφαῖρα (''sphaira''), meaning "sphere," and αλκεα (''alkea''), meaning "mallow." The leaves of these plants are spirally arranged, and usually palmate or toothed. Both stems and leaves are downy. Like other Malvaceae, the flowers are saucer- or cup-shaped, with the stamens joined into a column in the center. ''Sphaeralcea'' species are used as food plants by the larvae of some Lepidoptera species including '' Schinia olivacea'', which has been recorded on ''S. lindheimeri''. Selected species *''Sphaeralcea ambigua'' A.Gray – Desert globemallow *'' Sphaeralcea angustifolia'' (Cav.) G.Don ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grape
A grape is a fruit, botanically a berry, of the deciduous woody vines of the flowering plant genus ''Vitis''. Grapes are a non- climacteric type of fruit, generally occurring in clusters. The cultivation of grapes began perhaps 8,000 years ago, and the fruit has been used as human food over history. Eaten fresh or in dried form (as raisins, currants and sultanas), grapes also hold cultural significance in many parts of the world, particularly for their role in winemaking. Other grape-derived products include various types of jam, juice, vinegar and oil. History The Middle East is generally described as the homeland of grape and the cultivation of this plant began there 6,000–8,000 years ago. Yeast, one of the earliest domesticated microorganisms, occurs naturally on the skins of grapes, leading to the discovery of alcoholic drinks such as wine. The earliest archeological evidence for a dominant position of wine-making in human culture dates from 8,000 years ago in Georg ...

Yucca
''Yucca'' is a genus of perennial shrubs and trees in the family Asparagaceae, subfamily Agavoideae. Its 40–50 species are notable for their rosettes of evergreen, tough, sword-shaped leaves and large terminal panicles of white or whitish flowers. They are native to the hot and dry (arid) parts of the Americas and the Caribbean. Early reports of the species were confused with the cassava (''Manihot esculenta''). Consequently, Linnaeus mistakenly derived the generic name from the Taíno word for the latter, ''yuca''. The Aztecs living in Mexico since before the Spanish arrival, in Nahuatl, call the local yucca species (''Yucca gigantea'') , which gave the Spanish . is also used for ''Yucca filifera''. Distribution The natural distribution range of the genus ''Yucca'' (49 species and 24 subspecies) covers a vast area of the Americas. The genus is represented throughout Mexico and extends into Guatemala (''Yucca guatemalensis''). It also extends to the north through Baja Cali ...

Agave
''Agave'' (; ; ) is a genus of monocots native to the hot and arid regions of the Americas and the Caribbean, although some ''Agave'' species are also native to tropical areas of North America, such as Mexico. The genus is primarily known for its succulent and xerophytic species that typically form large rosettes of strong, fleshy leaves. ''Agave'' now includes species formerly placed in a number of other genera, such as ''Manfreda'', ×''Mangave'', ''Polianthes'' and ''Prochnyanthes''. Many plants in this genus may be considered perennial, because they require several to many years to mature and flower. However, most ''Agave'' species are more accurately described as monocarpic rosettes or multiannuals, since each individual rosette flowers only once and then dies; a small number of ''Agave'' species are polycarpic. Maguey flowers are considered edible in many indigenous culinary traditions of Mesoamerica. Along with plants from the closely related genera ''Yucca'', ''Hes ...
