Nevada in Maps is a nice collection of more than 4,000 maps and atlases from the collections of the University of Nevada at Reno and Las Vegas, the State Library, and the Nevada State Historical Society. The collections mostly date from the mid-19th to the mid-20th centuries, and include topo maps (1863-1968), geologic and mining district maps and atlases (1863-1968), highway maps (1917-2005), and survey plats (1867-1927).
A sub-site, Nevada History in Maps, goes further back, draws on more sources, and focuses on the discovery and settlement of the area. At right: Colton’s Territories of New Mexico and Utah (1855) (Nevada Historical Society and the DeLaMare Library, University of Nevada, Reno). Via MAPS-L.
