Description This 1:100,000-scale Geologic Map of Montana dataset is the result of many years of mapping, interpretation, editing, and updating by a large team of geologists and GIS professionals. This map is available as DM 3, which is updated at regular intervals and can be accessed as an interactive map or downloaded as a GIS Data Bundle from the links on this page. DM 3 is considered a preliminary, unpublished dataset. The dataset includes those areas where mapping at 1:100,000 scale is complete.
