Seamless Integrated Geologic Map Database of the Intermountain West: Contributions to The National Geologic Map (ver. 2.0, October 2024)

This dataset is intended to provide seamless, integrated geologic mapping of the U.S. Intermountain West region and is supported by the National Cooperative Geologic Mapping Program of the U.S. Geological Survey. Surficial and bedrock geology are included in this data release as independent datasets at a variable resolution from 1:50,000 to 1:250,000 scale. Initial contributions to this data release are along an east-west transect along 37-degrees north latitude that extends from the Rio Grande Rift and Great Plains in the east to the Basin and Range and Sierra Nevada to the west. Other areas of the Intermountain West region will be incorporated over time. Data are presented as downloadable file geodatabases (*.gdb) and as features services that can be directly ingested into GIS software for analysis. Data are available through child items associated with this data release. This dataset is intended to be versioned regularly as new geologic map data is integrated.
