A mesa is an isolated, flat-topped elevation , ridge or hill , which is bounded from all sides by steep escarpments and stands distinctly above a surrounding plain . Mesas characteristically consist of flat-lying soft sedimentary rocks capped by a more resistant layer or layers of harder rock , e.g. shales overlain by sandstones . The resistant layer acts as a caprock that forms the flat summit of a mesa. The caprock can consist of either sedimentary rocks such as sandstone and limestone ; dissected lava flows ; or a deeply eroded duricrust . Unlike plateau , whose usage does not imply horizontal layers of bedrock , e.g. Tibetan Plateau , the term mesa applies exclusively to the landforms built of flat-lying strata . Instead, flat-topped plateaus are specifically known as tablelands .

A mesa is similar to, but has a more extensive summit area than a butte . There is no agreed size limit that separates mesas from either buttes or plateaus. For example, the flat-topped mountains which are known as mesas in the Cockburn Range of North Western Australia have areas as large as 350 km (140 sq mi). In contrast, flat topped hills with areas as small as 0.1 km (0.039 sq mi) in

When the cliff edge does not retreat uniformly but instead is indented by headward eroding streams, a section can be cut off from the main cliff, forming a mesa. Basal sapping occurs as water flowing around the rock layers of the mesa erodes the underlying soft shale layers, either as surface runoff from
3195-492: The climate transitions progressively toward a semiarid zone (Köppen BSk ) in the high plains of the Panhandle and other western areas from about Lawton westward, less frequently touched by southern moisture. Precipitation and temperatures decline from east to west accordingly, with areas in the southeast averaging an annual temperature of 62 °F (17 °C) and an annual rainfall of generally over 40 in (1,020 mm) and up to 56 in (1,420 mm), while areas of
3266-483: The flat top, or caprock , of a mesa. The less resistant rock layers are mainly made up of shale , a softer rock that weathers and erodes more easily. The differences in strength of various rock layers are what give mesas their distinctive shape. Less resistant rocks are eroded away on the surface into valleys, where they collect water drainage from the surrounding area, while the more resistant layers are left standing out. A large area of very resistant rock, such as
3337-415: The land allotted to individual Indian heads of families became white-owned. Allottees often sold or were fraudulently deprived of their land. The acquisition of tribal lands by the U.S. government led to land runs , also called "land rushes," from 1887 and 1895. Major land runs, including the Land Rush of 1889 , opened up millions of acres of formerly tribal lands to white settlement. The "rushes" began at

As the underlying shale erodes away, it can no longer support the overlying cliff layers, which collapse and retreat. When the caprock has caved away to the point where only little remains, it is known as a butte . Many but not all American mesas lie within the Basin and Range Province . A transitional zone on Mars , known as fretted terrain , lies between highly cratered highlands and less cratered lowlands. The younger lowland exhibits steep walled mesas and knobs . The mesa and knobs are separated by flat lying lowlands. They are thought to form from ice-facilitated mass wasting processes from ground or atmospheric sources. The mesas and knobs decrease in size with increasing distance from
