The following are pages relevant to the Minneapolis area (with the exception of page 36) taken from the book An Introduction to Caves of Minnesota, Iowa, and Wisconsin: Guidebook for the 1980 National Speleological Society Convention, edited by E. Calvin Alexander, Jr. The majority of the "caves" are mines in the vicinity of Bassett Island. If anybody knows of any other significant (over ~50 feet of passage) caves or mines in the area, please e-mail me at jhollison@rocketmail.com.
