Maps

Our programs produce accurate geologic maps and 3-D geologic frameworks that provide critical data for sustaining and improving the quality of life and economic vitality of the Nation. They also organize, maintain, and publish the geospatial baseline of the Nation's topography, natural landscape, built environment and more.

Geologic map of the Sherbrooke-Lewiston area, Maine, New Hampshire, and Vermont, United States, and Quebec, Canada

This map is part of a folio of maps of the Lewiston 1° x 2° quadrangle, Maine, New Hampshire, and Vermont, and part of the Sherbrooke 1° x 2° quadrangle, Maine, New Hampshire, and Vermont, United States, and Quebec, Canada, prepared under the Conterminous United States Mineral Assessment Program (CUSMAP). Adjacent areas in Quebec are shown, in order to illustrate the geologic continuity between no

Geologic/geomorphologic map of the Chryse Planitia region of Mars

Since the 1970’s, when the Mariner 9 spacecraft revealed the geologic diversity of Mars, the Chryse Planitia region has been noted for its immense outflow channels and chaotic terrain (McCauley and others, 1972; Sharp and Malin, 1975; Baker, 1982, chap. 3; Mars Channel Working Group, 1983). Various proposals for the origin of these features have been offered; most workers have favored a mechanism

Map of Mars showing channels and possible paleolake basins

The significance of water in the geologic evolution of Mars was strikingly revealed by Mariner and Viking spacecraft images.  Theoretical and conceptual models of the Martian climate through time range from a brief, early, warm, and wet period followed by protracted desertification to episodic oceans that inundated the northern lowland plains and produced temperate climatic regimes.
