The Mullan Road: Carving a Passage through the Frontier Northwest, 1859-62, edited by Paul D. McDermott, Ronald E. Grim, and Philip Mobley (Mountain Press Publishing Company) is a beautifully illustrated book that is backed up with detailed annotations which represent years of research by the contributors. Even more intriguing to readers interested in the history of the road’s construction from Walla Walla, Washington Territory to Fort Benton on the Missouri River (future Montana Territory) is that the book can be used as an excellent travel guide for heritage road trips across Oregon, Washington, Idaho and Montana in search of Mullan’s 624-mile, military wagon road.
