New Bedrock Geologic Map of Minnesota published

The Minnesota Geological Survey has released a new bedrock geologic map of the state.

State Geologist Harvey Thorleifson notes that "While this map has renewed our thinking comprehensively, our focus very much remains on county-scale, 1:100,000 3D mapping, which results in the geologic maps that are used in groundwater protection and other management applications – this is by far our principal role. Our County Geologic Atlas program is very active, and growing."
