Bedrock in Pine County is mostly covered by glacial sediment that varies in thickness from a few feet to more than 300 feet. The thickest glacial sediment in the county is in the central part of the northern border of the county, along the southern boundary of the county, and where channels were cut into bedrock prior to deposition of the glacial sediment. The thinnest glacial cover is found in a broad northeast-to-southwest band across the center of the county and in areas where present-day rivers and streams have cut into the glacial materials. The most extensive bedrock exposures are along the Kettle River about five miles north and south of Sandstone. Another significant concentration of bedrock outcrops is in the area of Denham in the northwestern part of the county. Most other exposures of bedrock in Pine County are small and widely scattered.
