Wyoming Historical Maps and Atlases

The state of Wyoming collection contains 48 atlases spanning 129 years of growth and development (1870 through 1999). Within the atlases are 1,715 historical maps, illustrations, and histories many of which contain family names ideal for genealogical research. Others are rare antique maps, part of the collection by an exclusive arrangement with the Osher Map Library. The state of Wyoming has 13 of these antiquarian maps dating back as early as 1870.
