Borehole Geophysical Database Portal

The Minnesota Geological Survey's Borehole Geophysical Database (BGD) is a collection of over 7,000 borehole geophysical and video logs of water wells and drill holes throughout Minnesota.

This newly updated portal and web map provides more information about the various geophysical logs we collect, while providing enhanced public access to their spatial location and the ability to view/download pertinent data.
