The Minnesota Geological Survey invites non-geologists to examine the rocks and fossils in the Rochester area on this field trip. We welcome all persons regardless of their backgrounds in geology and hope that this guidebook will help make what is seen here more understandable. If any word or explanation is not clear to you, please ask any of the geologists on the trip to explain it to you.
