County Atlas Status List

A County Geologic Atlas (CGA) provides information about the geology and groundwater resources of a county, including the groundwater quality, quantity, and sensitivity to pollution. Paper copies can be obtained from MGS Map Sales.

Part A - Geologic Atlas

The Minnesota Geological Survey produces the Part A atlas, which includes the geology, geologic layering, sand distribution, bedrock surface, and depth to bedrock for a specific county.

Part B - Groundwater Atlas

The DNR produces the Part B atlas, which includes maps and reports identifying the direction of groundwater flow, aquifer properties, groundwater chemistry, and pollution sensitivity of aquifers.
