Abstract:
 Compilation of 100,000 scale bedrock maps from MGS County Atlas products beginning with C-08, Fillmore County and ending with the newest Atlas, the Bedrock Geology of Lake County Minnesota for a total of 45 100k maps. Because the maps have been created by different authors over a significant time period, the edges of each map do not always align with adjacent maps and for this project no attempt was made to harmonize them. In addition, the map units may also have been change or updated between products separated by several years. However, in this compilation a single attribute table has been developed that includes all of the map labels as well as descriptive text and other fields that allow interpretations to be made between maps. Many of the map units are also part of the 2011 bedrock geologic map of Minnesota which provides another method of interpretation and description. In addition, the source field identifies which Atlas the polygons were originally part of and which will have additional information available about the units. This map is the foundation of a database of 100,000 bedrock mapping in Minnesota that is intended to be updated as new County Atlas mapping is completed and as time permits to be used to develop a common index of bedrock geologic units in Minnesota.

Purpose:
 This map brings together digital bedrock polygons from Minnesota bedrock maps from County Geologic Atlas products published since 1995, without harmonization or matching of map edge boundaries.
