Maps can be very useful in conducting Montana research, especially in light of the now extinct communities. Several kinds of maps are available which can help in locating land, mining claims, ghost towns, or ranches.
The U.S. Geological Survey topographical maps (see page 5) for Montana can be ordered through the USGS website or the Montana office at 3162 Bozeman Ave., Helena, MT 59601. Topographical maps for Montana can also be found online at www.topozone.com/.
The libraries in the state designated by the U.S. Geological Survey as map depository libraries are the Montana Historical Society; Montana State University–Billings; Montana State University–Bozeman; Montana Tech at the University of Montana, Butte; Montana State University–Northern, Havre; Montana State Library, Helena; and the University of Montana, Missoula.
The state lacks a historical atlas; however, Roberta Cheney, Names on the Face of Montana, rev. ed. (Missoula, Mont.: Mountain Press, 1987) can prove helpful in locating places during specific time periods.
