Digital Data for the Geologic Map of the Central Beaverhead Mountains, Lemhi County, Idaho, and Beaverhead County, Montana

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-09-29T00:00:00Z
This Data Release contains geospatially-enabled geological data to accompany the Geologic Map of the Central Beaverhead Mountains, Lemhi County, Idaho, and Beaverhead County, Montana. This map portrays detailed geology of the central Beaverhead Mountains, printable at 1:50,000 scale. These data were collected between 1997 and 2017, and synthesized to provide significant new stratigraphic and structural data and interpretations. Generalized basin geology compiled from sources on both sides of the range is combined with newly mapped bedrock geology to better integrate geologic development of the map area.
