Updated GIS data for 1:250,000-scale surficial geologic mapping

We have republished our 1:250,000-scale digital mapping data to our Geologic Information Portal. This data was originally created in 2010 and includes folds, faults, contacts, and geologic units mapped at a statewide scale. The update involved conversion of the existing dataset into a new federal data schema called ‘GeMS’. You can read more about this conversion […]

New geologic mapping data at scales of 1:25,000 to 1:99,000 on our portal

We are pleased to announce the publication of a new dataset available for download and viewable on the Geologic Information Portal. The 1:25,000-1:99,000-scale surface geology dataset (listed as 25-99k Surface Geology on the portal) was added to the portal to host published geologic maps in the intermediate range between the more common 24k and 100k […]
