 "description": "Statewide maps of bedrock geology from the Minnesota Geological Survey (MGS). There is a general map of bedrock geology that is shown at smaller scales for very general reference. As you zoom in the S-21 Statewide MGS Bedrock Geology is shown. This map is a recent construct that incorporates existing geologic maps where prior mappers had adequate ground control, and new interpretations based on drill hole, geophysical, and unpublished data where they did not. The interpretation differs significantly from previous maps to reflect new data and accommodate scale. It portrays our current geologic understanding of the temporal and geographic distribution of units within major Precambrian terranes and of the Phanerozoic strata. The western part of the mapped Precambrian terrane is inferred largely from geophysical maps, anchored locally by drilling. In many places, contacts are drawn between units of the same or similar apparent rock type (and same unit label); these are recognized as geometrically distinct, though geophysically or lithologically similar. Digital files corresponding to this map allow removal of Cretaceous, Paleozoic, and some parts of Mesoproterozoic strata to reveal an interpretation of the underlying Precambrian bedrock.\n\nMore information can be found at: https://conservancy.umn.edu/handle/11299/101466",
