Tinaja
Tinaja is a term originating in Spain (Spanish for clay jar) and used in the American Southwest for surface pockets (depressions) formed in bedrock that occur below waterfalls, are carved out by spring flow or seepage, or are caused by sand and gravel scouring in intermittent streams (arroyos). Tinajas are an important source of surface water storage in arid environments. These relatively rare landforms are important ecologically, because they support unique plant communities and provide important services to terrestrial wildlife.National Park Service (NPS). 2006.Organ Pipe Cactus National Monument Ecological Monitoring Report 1997–2005, Chapter 14: Water Quality.http://www.nps.gov/orpi/naturescience/orpi-ecological-monitoring-report.htm Examples * The Tinajas Altas ("high tinajas") in southern Arizona. * Several in El Pinacate y Gran Desierto de Altar Biosphere Reserve, Sonora, Mexico. *Las Tinajas de Los Indios, California *Las Tinajas, Zinapécuaro Las Tinajas (, " the ...

Tinajas Altas
El Camino del Diablo (Spanish, meaning "The Devil's Highway"), also known as El Camino del Muerto, Sonora Trail, Sonoyta-Yuma Trail, Yuma-Caborca Trail, and Old Yuma Trail, is a historic road that passes through some of the most remote and inhospitable terrain of the Sonoran Desert in Pima County and Yuma County, Arizona. The name refers to the harsh, unforgiving conditions on the trail. In use for thousands of years, El Camino del Diablo began as a series of footpaths used by desert-dwelling Native Americans. From the 16th to the 19th centuries, the road was used extensively by conquistadores, explorers, missionaries, settlers, miners, and cartographers. Use of the trail declined sharply after the Southern Pacific Railroad reached Yuma in 1877. In recognition of its historic significance, El Camino del Diablo was listed on the National Register of Historic Places in 1978. It has also been designated a Back Country Byway by the Bureau of Land Management. Original route Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
El Pinacate Y Gran Desierto De Altar Biosphere Reserve
El Pinacate y Gran Desierto de Altar Biosphere Reserve ( es, Reserva de la Biosfera El Pinacate y Gran Desierto de Altar) is a biosphere reserve and UNESCO World Heritage Site managed by the federal government of Mexico, specifically by Secretariat of the Environment and Natural Resources, in collaboration with the state governments of Sonora and the Tohono O'odham. It is in the Sonoran Desert in northwest Mexico, east of the Gulf of California, in the eastern part of the Gran Desierto de Altar, just south of the border with Arizona, United States and north of the city of Puerto Peñasco. It is one of the most significant visible landforms in North America seen from space. A volcanic system known as Santa Clara is the main part of the landscape, including three peaks: Pinacate, Carnegie and Medio. In the area there are over 540 species of plants, 40 species of mammals, 200 of birds, 40 of reptiles, amphibians and freshwater fishes. There are threatened endemic species as Sono ...

Las Tinajas De Los Indios
Las Tinajas de Los Indios, or "Indian Tanks", are tinajas located in the sandstone heights of the Point of Rocks on the north side of Antelope Valley in Kern County, California.Frank F. Latta, ''El Camino Viejo á Los Angeles - The Oldest Road of the San Joaquin Valley''; Bear State Books, Exeter, 2006, pp. 10-11; Reprint of the 1936 work by Frank F. Latta, of an address he delivered before the Kern County Historical Society, February 20, 1933, and published by it as its second annual publication, in 1936. History ''Las Tinajas de Los Indios'' (The Jars of the Indians), later called "Indian Tanks", was as its name suggests, the site of an Indian encampment. The tops of the Point of Rocks, sandstone rock formations, have ''tinajas'', (''jars'' in Spanish), natural basins that acted as reservoirs or cisterns to hold the water that collected during the winter rains and held it throughout the summer. These tinajas bear evidence of having been improved by the Indians. Deeply worn s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Southwest
The Southwestern United States, also known as the American Southwest or simply the Southwest, is a geographic and cultural region of the United States that generally includes Arizona, New Mexico, and adjacent portions of California, Colorado, Nevada, Oklahoma, Texas, and Utah. The largest cities by metropolitan area are Phoenix, Las Vegas, El Paso, Albuquerque, and Tucson. Prior to 1848, in the historical region of Santa Fe de Nuevo México as well as parts of Alta California and Coahuila y Tejas, settlement was almost non-existent outside of Nuevo México's Pueblos and Spanish or Mexican municipalities. Much of the area had been a part of New Spain and Mexico until the United States acquired the area through the Treaty of Guadalupe Hidalgo in 1848 and the smaller Gadsden Purchase in 1854. While the region's boundaries are not officially defined, there have been attempts to do so. One such definition is from the Mojave Desert in California in the west (117° west longitud ...

Bedrock
In geology, bedrock is solid Rock (geology), rock that lies under loose material (regolith) within the crust (geology), crust of Earth or another terrestrial planet. Definition Bedrock is the solid rock that underlies looser surface material. An exposed portion of bedrock is often called an outcrop. The various kinds of broken and weathered rock material, such as soil and subsoil, that may overlie the bedrock are known as regolith. Engineering geology The surface of the bedrock beneath the soil cover (regolith) is also known as ''rockhead'' in engineering geology, and its identification by digging, drilling or geophysics, geophysical methods is an important task in most civil engineering projects. Superficial deposition (geology), deposits can be very thick, such that the bedrock lies hundreds of meters below the surface. Weathering of bedrock Exposed bedrock experiences weathering, which may be physical or chemical, and which alters the structure of the rock to leave ...

Arid
A region is arid when it severely lacks available water, to the extent of hindering or preventing the growth and development of plant and animal life. Regions with arid climates tend to lack vegetation and are called xeric or desertic. Most arid climates straddle the Equator; these regions include parts of Africa, Asia, South America, North America, and Australia. Change over time The distribution of aridity at any time is largely the result of the general circulation of the atmosphere. The latter does change significantly over time through climate change. For example, temperature increase by 1.5–2.1 percent across the Nile Basin over the next 30–40 years could change the region from semi-arid to arid, significantly reducing the land usable for agriculture. In addition, changes in land use can increase demands on soil water and thereby increase aridity.

Geomorphology
Geomorphology (from Ancient Greek: , ', "earth"; , ', "form"; and , ', "study") is the scientific study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near Earth's surface. Geomorphologists seek to understand why landscapes look the way they do, to understand landform and terrain history and dynamics and to predict changes through a combination of field observations, physical experiments and numerical modeling. Geomorphologists work within disciplines such as physical geography, geology, geodesy, engineering geology, archaeology, climatology, and geotechnical engineering. This broad base of interests contributes to many research styles and interests within the field. Overview Earth's surface is modified by a combination of surface processes that shape landscapes, and geologic processes that cause tectonic uplift and subsidence, and shape the coastal geography. Surface processes co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Water Streams
A stream is a continuous body of surface water flowing within the bed and banks of a channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long large streams are usually called rivers, while smaller, less voluminous and more intermittent streams are known as streamlets, brooks or creeks. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighted subterranean water, and surfaced groundwater (spring water). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes that respond to geological, geomorphological, hydrological and biotic controls. Streams are important as conduits in the water cycle, instruments in groundwater re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluvial Landforms
In geography and geology, fluvial processes are associated with rivers and streams and the deposits and landforms created by them. When the stream or rivers are associated with glaciers, ice sheets, or ice caps, the term glaciofluvial or fluvioglacial is used. Fluvial processes Fluvial processes include the motion of sediment and erosion or deposition on the river bed. The movement of water across the stream bed exerts a shear stress directly onto the bed. If the cohesive strength of the substrate is lower than the shear exerted, or the bed is composed of loose sediment which can be mobilized by such stresses, then the bed will be lowered purely by clearwater flow. In addition, if the river carries significant quantities of sediment, this material can act as tools to enhance wear of the bed ( abrasion). At the same time the fragments themselves are ground down, becoming smaller and more rounded (attrition). Sediment in rivers is transported as either bedload (the coarser frag ...

Habitats
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
