In-Progress Activities

• A database of formation-top elevations is in preparation. This database is being compiled from evaluation and comparison of information in:
• the Geological Survey Program's lithologic logs and geophysical logs databases
• the Minerals and Mining Program's oil and gas database and permit files
• the Water Rights Program's water-right permits database and well-completion reports


• Work is ongoing to ensure that information is consistent for records, or parts of records, that exist in multiple sources. Discrepancies between the various sources of information will be tracked, reconciled, and updated. This is essential for purposes of internal consistency and dissemination of information to the public


• Maps of surface geology at a scale of 1:250,000 are being completed and will be published for areas in South Dakota west of the Missouri River. The following 1° x 2° quadrangles are in-progress or planned: Hot Springs, Mitchell, and Pierre. Completed maps are available in Adobe PDF and GIS formats.
