Abstract
The Mare Boreum geologic map portrays the north polar area of Mars above lat 65˚ N. The area contains five physiographic provinces: (1) a residual ice cap characterized by troughs with a counterclockwise outward spiral pattern (Mariner 9 frames DAS 13317550 and DAS 13353320); (2) layered terrain adjacent to the ice cap, exposed within the spiral troughs; (3) a circumpolar band of low-albedo material extending roughly from lat 75˚ to 82˚ N; (4) isolated patches of high-albedo perennial ice near lat 75˚ N. within a semicircumpolar band between long 120˚ and 270˚; and (5) circumpolar cratered plains of mottled albedo south of lat 75˚.
