This open-file of bedrock elevation (be) and depth to bedrock (dt) grids and data points
for Minnesota represents the first phase of an ongoing process to create new statewide
maps from these data. All shapefiles and grids are compressed into the zip file ofr06_02.zip for distribution. The bedrock topography PDF and the Depth to Bedrock PDF have been updated in 2010 as part of the new bedrock geology map of Minnesota, see Open File report OFR10_02.
