The Chyrse Planitia region has been noted for its immense outflow channel and chaotic terrain (McCauley and othrs, 1972; Sharp and Malin, 1975; Baker, 1982, chap. 3; Mars Channel Working Group, 1983). Various proposals for the origin of these features have been offersd; most workers have favored a mechanism in which ground water or water-rich debris was expelled from beneath a frozen crust, leading to catastrophic debris flows or floods that may have contained significant amounts of ice (Baker and Milton, 1974; Carr, 1979; Nummedal and Prior, 1981; Luchitta, 1982; MacKinnon and tanaka, 1989). The channels originated on or near the flanks of volcanotectonic rises of Tharsis (whose east margin is the west edge of the map region) and Valles Marineris, which suggests that tectonic and igneous actvitiy led to the conditions of discharge. Estimated discharge rates for some channels exceed those of prehistoric floods on Earth (Carr, 1979; Komar, 1979; Robinson and Tanaka, 1986). Earlier geolgic mapping of the region basedon Mariner 9 mages identified chaotic materials, channel, canyons, and other units and features and their sequence of formation (Milton, 1974; Wilhelms, 1976; McCauley, 1978; Saunders, 1979). Further refinements of the ages of the units and their interretaion and global corelation follwed, based on the higher quality Viking images (Greeley and others, 1977; Masursky and others, 1977; meukum and Hiller, 1981; Scott and Tanaka, 1986; Tanaka, 1986). However, these mapping efforts did not reconstruct the detailed geologic history of the region that has significant implications for the planet's hydrologic and climatic histrories. To help resolve these problems, we have mapped the region on a shaded relief map especially designed for this purpose (U.S. Geological Survey, 1982).
