Library of Congress: Digital Collections - Mapping the National Parks

https://www.loc.gov/collections/national-parks-maps/about-this-collection

The Library of Congress offers this digital collection of 173 maps that either document U.S. national parks or document regions that would later be designated as national parks. More specifically, the collection documents depictions of four parks (Yellowstone, Acadia, the Grand Canyon, and the Great Smoky Mountains) and includes items dating from the seventeenth century through the present. This collection showcases maps that were created for a variety of purposes and features seventeenth-century maps by European explorers, eighteenth-century property maps, U.S. Geological Survey maps, and more. Visitors may browse these maps by date, location, contributor, or subject. In addition, visitors may want to check out the articles & essays section, which includes five essays that provide additional insight into these maps. In one such essay, Library of Congress cartographer Patricia Molen van Ee traces the history of mapping the coast of Maine (and Acadia National Park) from 1856 through the 1990s. Her essay is accompanied by a number of maps in the collection
