Geologic/geomorphologic map of the Chryse Planitia region of Mars 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...
Map of Mars showing channels and possible paleolake basins 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.

Quaternary Geologic Map of the Lake of the Woods 4 Degrees x 6 Degrees Quadrangle, United States and Canada Quaternary Geologic Map of the Lake of the Woods 4 Degrees x 6 Degrees Quadrangle, United States and Canada
The Quaternary Geologic Map of the Lake of the Woods 4 deg x 6 deg Quadrangle, United States and Canada, was mapped as part of the U.S. Geological Survey Quaternary Geologic Atlas of the United States map series (Miscellaneous Investigations Series I-1420, NM-15). The atlas was begun as an effort to depict the areal distribution of surficial geologic deposits and other materials that...
