Hello all,
Just wanted to post an FYI on some research items I came across that might be beneficial to the rest of us hunting in the Treasure state. The University of Montana Mansfield Library has access to old Sanborn maps for my cities in Montana. From this, I was able to acquire many old Great Falls maps from 1900/1920/1956, etc. The website and login info is included below:
