Park Service releases digital geologic map of Glen Canyon National Recreation Area

The National Park Service has released the Digital Geologic Map of Glen Canyon National Recreation Area and Vicinity, Utah and Arizona (GRI MapCode GLCA), which is posted at

The GLCA map covers in extent all of the park, as well as Rainbow Bridge National Monument, and portions of Canyonlands National Park, Capitol Reef National Park and Grand Canyon National Park. The map is also available in KMZ/KML format for use in Google Earth.

The map is produced by the NPS Geologic Resources Division as part of the Geologic Resources Inventory (GRI) program. In addition to the digital geologic maps, the GRI program also produces geologic reports that tie the digital geologic map to the geologic features, issues, and processes relevant to geologic resource management. The report for GLCA is forthcoming.
