The story of travel and exploration across the American West is treated in this ongoing series of monographs. From the well-known to the obscure, the routes of explorers, pioneers, and travelers are examined in detail. Though predominantly textual, each volume includes maps and other supplemental materials. Included are such classics as Hebard and Brininstool's Bozeman Trail, Conkling's Butterfield Overland Mail, and important works on the great western migration.
