Plat maps are available for all 87 counties in Minnesota and many counties in adjoining states. Each page in a county book details a 6-by-6 square mile township. Where to buy plat maps:
• County government offices
• Newspaper publishers in county seat towns, in some cases
• From Rockford Map Publishers, Inc. (800-321-1627) http://www.rockfordmap.com
• Farm and Home Publishers (800-685-7432) http://www.farmandhomepublishers.com
A county book costs about $30 to $40, but the value they deliver is priceless.
