Mesa

(mā`sə), city (1990 pop. 288,091), Maricopa co., S central Ariz., in the irrigated Salt River valley; inc. 1883. Electronic components, fabricated metals, aircraft, and machine tools are among its various manufactures. One of the fastest-growing U.S. cities, Mesa's population has more than doubled since 1980. Tourism is important, and the citrus and farm products of the area are packed and processed in Mesa. The Mormons who founded the city in 1878 used old Native American irrigation canals for farming in the Salt River valley. In Mesa are the Mesa Art Center, a Mormon temple, and the chief agricultural experiment farm of the Univ. of Arizona. The Chicago Cubs baseball team also has a spring training camp there.

mesa

(mā`sə) [Span.,=table], name given in the SW United States to a small, isolated tableland or a flat-topped hill. Two or more of the sides are steep and usually perpendicular and some have all four sides practically perpendicular. Their bold lines make them a picturesque part of the landscape, and they are frequently deep red or yellow in color. Mesas originate from the erosionerosion
, general term for the processes by which the surface of the earth is constantly being worn away. The principal agents are gravity, running water, near-shore waves, ice (mostly glaciers), and wind.

elevated, level or nearly level portion of the earth's surface, larger in summit area than a mountain and bounded on at least one side by steep slopes, occurring on land or in oceans.

 that were capped by hard rock, usually in arid regions. Cliffs form, retreating as the soft layers beneath the cap rock are eroded. As the soft rock wears away, the upper cliff breaks along cracks and eventually produces a mesa. A buttebutte,
an isolated hill with steep sides and a flat top, resulting from the more rapid erosion of the surrounding areas. Buttes are characteristic of the plains of the W United States. See mesa.

 is the last stage of the sequence, before the feature's complete consumption by erosion. The strata, or layers of rock, in a mesa are horizontal, or nearly so. The many "table mountains" are mesas. Two celebrated mesas are the Mesa Verde in Colorado and the Enchanted Mesa (Mesa Encantada) in New Mexico.

Mesa

Xerox PARC, 1977. System and application programming for proprietary hardware: Alto, Dolphin, Dorado and Dandelion. Pascal-like syntax, ALGOL68-like semantics. An early version was weakly typed. Mesa's modules with separately compilable definition and implementation parts directly led to Wirth's design for Modula. Threads, coroutines (fork/join), exceptions, and monitors. Type checking may be disabled. Mesa was used internally by Xerox to develop ViewPoint, the Xerox Star, MDE, and the controller of a high-end copier. It was released to a few universitites in 1985. Succeeded by Cedar.

A semiconductor process used in the 1960s for creating the sublayers in a transistor. Its deep etching gave way to the planar process.
