Parts of Herb Wright's map of glacial landforms in central and NE Minnesota, for a field trip in 1956. Includes several drumlin fields, moraines (gray shade), and drainageways (some of which are tunnel channels). When I took glacial geology at U of MN, we met Herb at a gravel pit on the map at left.
