The North America tapestry of time and terrain The North America tapestry of time and terrain
The North America Tapestry of Time and Terrain (1:8,000,000 scale) is a product of the US Geological Survey in the I-map series (I-2781). This map was prepared in collaboration with the Geological Survey of Canada and the Mexican Consejo Recursos de Minerales. This cartographic Tapestry is woven from a geologic map and a shaded relief image. This digital combination reveals the geologic...
Map of flows from Pu‘u ‘Ō‘ō: September 12, 2003 Map of flows from Pu‘u ‘Ō‘ō: September 12, 2003
Map shows lava flows erupted during 1983-present activity of Pu‘u ‘Ō‘ō and Kupaianaha. Red colors, both dark and light, denote Mother's Day flow, which began erupting on May 12, 2002 and continues to the present. The darkest color represents flows active since January 21, 2003.
Geologic map of the Ponca quadrangle, Newton, Boone, and Carroll Counties, Arkansas Geologic map of the Ponca quadrangle, Newton, Boone, and Carroll Counties, Arkansas
This digital geologic map compilation presents new polygon (i.e., geologic map unit contacts), line (i.e., fault, fold axis, and structure contour), and point (i.e., structural attitude, contact elevations) vector data for the Ponca 7 1/2' quadrangle in northern Arkansas. The map database, which is at 1:24,000-scale resolution, provides geologic coverage of an
Geologic map of the Salmon National Forest and vicinity, east-central Idaho Geologic map of the Salmon National Forest and vicinity, east-central Idaho
The geology of the Salmon National Forest, Idaho, was compiled from published and unpublished sources and new field mapping by Evans, Lund, Tysdal, and Winkler between 1997 and 2001. The geology was compiled onto 1:100,000-scale topographic base maps for input into a geographic information system (GIS). The digital geologic map database can be queried
Map of surficial deposits and materials in the eastern and central United States (east of 102 degrees West longitude) Map of surficial deposits and materials in the eastern and central United States (east of 102 degrees West longitude)
This data set contains surficial geologic units in the Eastern and Central United States, as well as a glacial limit line showing the position of maximum glacial advance during various geologic time periods. The geologic units represent surficial deposits and other surface materials that accumulated or formed during the past 2+ million years, such as soils
