This data layer depicts the Quaternary Geology of Minnesota at the 1:100,000 scale. It was developed by the Minnesota Geological Survey using data from the digital database D01 (map S23 was also derived from D01). It includes complete surficial geology from the Pleistocene (glacial) epoch and partial surficial geology from the Holocene (post-glacial) epoch. The type and distribution of geological materials at the land surface affects the distribution and character of groundwater, surface water, organisms, and natural processes.
