This data layer depicts the depth to bedrock of Minnesota at the 1:500,000 scale. It was developed by the Minnesota Geological Survey (map OFR 10-02). The thickness of the sediment covering the bedrock affects the distribution and character of groundwater, surface water, organisms, and natural processes.
