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.

It was made for printing and visualization. GIS files are available with the detailed digital database D-1 at the MGS Data Portal -- https://mngs-umn.opendata.arcgis.com/ and are not available in this archive. S-23 compiles new and previously published geologic mapping to show the surficial sediments in Minnesota as a printable !:500,000 scale version. In contrast to Hobbs and Goebel (1982), where map colors indicated provenance, on this map unit colors refer to texture: green for diamicton interpreted to be till, red/orange for sand and gravel-dominated sediments, and blue for silt and clay. Glacial sediments were mapped using lithostratigraphic formation names of Johnson and others (2016) and references therein. Post glacial and proglacial sediments were named for their genesis. Peat is shown in Figure 1. Modern lake sediment is not shown here. Refer to Figure 2 for the location of major provenances and the names and extent of ice lobes during the late Wisconsinan glaciation. Unless otherwise noted, the two-letter map-unit abbreviation indicates diamicton interpreted to be till of a particular formation. The addition of a third letter indicates associated sediments.
