Bigtooth Maple
''Acer grandidentatum'', commonly called bigtooth maple or western sugar maple, is a species of maple native to interior western North America. It occurs in scattered populations from western Montana to central Texas in the United States and south to Coahuila in northern Mexico. Description It is a small to medium-sized deciduous tree growing to tall and a trunk of diameter. The bark is dark brown to gray, with narrow fissures and flat ridges creating plate-like scales; it is thin and easily damaged. The leaves are opposite, simple, long and broad, with three to five deep, bluntly-pointed lobes, three of the lobes large and two small ones (not always present) at the leaf base; the three major lobes each have 3–5 small subsidiary lobules. The leaves turn golden yellow to red in autumn (less reliably in warmer areas). In Texas, specimens do not color well if they have a heavy seed year. The flowers appear with the leaves in mid spring; they are produced in corymbs of 5–15 to ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Wasatch Mountains
The Wasatch Range ( ) or Wasatch Mountains is a mountain range in the western United States that runs about from the Utah-Idaho border south to central Utah. It is the western edge of the greater Rocky Mountains, and the eastern edge of the Great Basin region.''Hiking the Wasatch'', John Veranth, 1988, Salt Lake City, The northern extension of the Wasatch Range, the Bear River Mountains, extends just into Idaho, constituting all of the Wasatch Range in that state. In the language of the native Ute people, Wasatch means "mountain pass" or "low pass over high range." According to William Bright, the mountains were named for a Shoshoni leader who was named with the Shoshoni term ''wasattsi'', meaning "blue heron". In 1926, Cecil Alter quoted Henry Gannett from 1902, who said that the word meant "land of many waters," then posited, "the word is a common one among the Shoshones, and is given to a berry basket" carried by women.

Lost Maples State Natural Area
Lost Maples State Natural Area is a area of hills and canyons on the upper Sabinal River in the Edwards Plateau Region of Texas. It is designated a ''Natural Area'', rather than a ''State Park'', which means the primary focus is the maintenance and protection of the property's natural state. Accordingly, access and recreational activities may be restricted if the Texas Parks & Wildlife Department (TPWD) deems such action necessary to protect the environment. Location The Lost Maples State Natural Area is located about north of Vanderpool, Texas, and northwest of San Antonio. The preserve sits along the Sabinal River in western Bandera County and far eastern Real County. History The land for Lost Maples State Natural Area was acquired by the state of Texas in 1973 and 1974, and was opened to the public in 1979. In 1980, the Heritage Conservation and Recreation Service made the Natural Area a National Natural Landmark. The area was named for its abundance of maples, wh ...

Humid Subtropical
A humid subtropical climate is a subtropical -temperate climate type, characterized by long and hot summers, and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates, and equatorward from either humid continental (in North America and Asia) or oceanic climates (in other continents). It is also known as warm temperate climate in some climate classifications. Under the Köppen climate classification, ''Cfa'' and ''Cwa'' climates are either described as humid subtropical climates or warm temperate climates. This climate features mean temperature in the coldest month between (or ) and and mean temperature in the warmest month or higher. However, while some climatologists have opted to describe this climate type as a "humid subtropical climate", Köppen himself never used this term. The humid subtropical climate classification ...

Continental Climate
Continental climates often have a significant annual variation in temperature (warm to hot summers and cold winters). They tend to occur in central and eastern parts of the three northern-tier continents (North America, Europe, and Asia), typically in the middle latitudes (40 to 55 or 60 degrees north), often within large landmasses, where prevailing winds blow overland bringing some precipitation, and temperatures are not moderated by oceans. Continental climates occur mostly in the Northern Hemisphere due to the large landmasses found there. Most of northeastern China, eastern and southeastern Europe, much of Russia south of the Arctic Circle, central and southeastern Canada, and the central and northeastern United States have this type of climate. Continentality is a measure of the degree to which a region experiences this type of climate. In continental climates, precipitation tends to be moderate in amount, concentrated mostly in the warmer months. Only a few areas—in th ...

Semi-arid
A semi-arid climate, semi-desert climate, or steppe climate is a aridity, dry climate sub-type. It is located on regions that receive precipitation below Evapotranspiration#Potential evapotranspiration, potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSh'' and ''BSk'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as they usually cannot support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to ...

Southwestern Oklahoma
Southwest Oklahoma is a geographical name for the southwest portion of the state of Oklahoma, typically considered to be south of the Canadian River, extending eastward from the Texas border to a line roughly from Weatherford, Oklahoma, Weatherford, to Anadarko, Oklahoma, Anadarko, to Duncan, Oklahoma, Duncan. Geologically, the region is defined by a failed continental rift known as the Southern Oklahoma Aulacogen. The austere nature of the prairie landscape with intermittent island ranges has made it a favorable place for artists and photographers alike. For tourism purposes, the Oklahoma Department of Tourism and Recreation, Oklahoma Tourism and Recreation Department has designated Southwestern Oklahoma as Great Plains Country, and defined it to consist of 14 counties including Roger Mills County, Oklahoma, Roger Mills, Custer County, Oklahoma, Custer, Beckham County, Oklahoma, Beckham, Washita County, Oklahoma, Washita, Caddo County, Oklahoma, Caddo, Kiowa County, Oklahoma, Ki ...

Wichita Mountains
The Wichita Mountains are located in the southwestern portion of the U.S. state of Oklahoma. It is the principal relief system in the Southern Oklahoma Aulacogen, being the result of a failed continental rift. The mountains are a northwest-southeast trending series of rocky promontories, many capped by 500 million-year old granite. These were exposed and rounded by weathering during the Pennsylvanian and Permian Periods. The eastern end of the mountains offers of topographic relief in a region otherwise dominated by gently rolling grasslands. The mountains are home to numerous working ranches and quarry operations, the state reformatory, recreational homes and campsites, and scenic parklands. Fort Sill, home of the U.S. Army Field Artillery School, occupies a large portion of the southeastern end of the mountains. Recreation The Wichita Mountains Wildlife Refuge (WMWR"), a favorite for hikers and rock climbers in the region, is located adjacent to Cache, Medicine Park, ...

Edwards Plateau
The Edwards Plateau is a geographic region forming the crossroads of Central, South and West Texas, United States. It is named in honor of Haden Edwards. It is bounded by the Balcones Fault to the south and east; the Llano Uplift and the Llano Estacado to the north; and the Pecos River and Chihuahuan Desert to the west. San Angelo, Austin, San Antonio and Del Rio roughly outline the area. The plateau, especially its southeast portion, is also known as the Texas Hill Country. Natural history The bedrock consists primarily of limestone, with elevations ranging between 100 and 3000 ft. Caves are numerous. The landscape of the plateau is mostly savanna scattered with trees. It mostly lacks deep soil suitable for farming, though the soil type is fertile mollisol, so some cotton, grain sorghum, and oats are grown. For the most part, though, the thin soil and rough terrain areas are primarily grazing regions, with cattle, sheep, and goats ( Angora and meat types) predom ...

Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly Dolomite (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...
