This preliminary data layer depicts the depth to bedrock at the 1:100,000 scale in portions of the Arrowhead region. It was developed by the Minnesota Geological Survey (map OFR 16-4) and is at a finer scale than the statewide Depth to Bedrock layer (map OFR 10-02). The thickness of the geological material covering the bedrock affects the distribution and character of groundwater, surface water, organisms, and natural processes.
