Historic 1:100,000 Scale Topographic Maps of Montana
These are historic topographic maps.  Users should be aware that significant changes may have occurred in the landscape since the maps were made.  Many of the maps are over 30 years old.

The Montana State Library provides the data for historical reference and because they contain hand-placed elevation and place name information that may not be available on newer maps.

These were the newest scanned topographic maps available from the U.S. Geological Survey TopoView web site as of November 2015. The data include the maps covering Montana and parts of Idaho and northern Wyoming.
