This data layer depicts the bedrock geology of Minnesota at the 1:500,000 scale. It was developed by the Minnesota Geological Survey (map S-21) and portrays the current geologic understanding of the temporal and geographic distribution of units within major Precambrian terranes and of the Phanerozoic strata. Bedrock geology forms the foundation upon which many other natural resource features of Minnesota are built.
