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 maps of the Descartes region of the Moon Apollo 16 pre-mission maps

The evolution of the Moon’s surface shows three successive stages (Hartmann, 1970). The earliest, from the beginning of the decipherable record to the Imbrian Period, was dominated by frequent large-scale impacts which produced overlapping and interfering craters and giant multi-ringed basin with ejecta blankets. The second stage, extending through most of the Imbrian to early Eratosthenian Period

Geologic maps of the Taurus-Littrow region of the Moon Apollo 17 pre-mission maps

The Taurus-Littrow region is mainly a highland area at the juncture of Mare Serenitatis and Mare Tranquillitatis (Scott and Pohn, 1972). Highland materials cover most of the area, forming a group or rugged massifs close to the center of the map and more subdued terrain to the east. The highland units (pItm, IpIh) are probably mostly breccias formed by the Serenitatis impact and pre-existing brecci

Landslide susceptibility in San Mateo County, California

Information on areas susceptible to failure by landsliding is available in many general geologic maps and reports.  However, it is commonly presented in complex, technical language, together with data not connected with slope stability.  This derivative map is intended to convey such information in nontechnical form so that it will be intelligible to the non-geologist.  It portrays only those geol
