This is a fascinating look at the mountain passes (the great gates) of the Rockies, starting in northern New Mexico and continuing north for 2,000 miles into Canada. Sprague starts his history of these passes in the 16th century, with the Spaniards, and continues through 1830 by which time, he says, all the passes had been discovered. The 21 chapters of this book give the history of at least 21 major mountain passes and the explorers who found them . . . or thought they did. An additional 150 pages contain the author's notes, a list of sources, acknowledgments, and an alphabetical list of the passes, divided by state or province: Passes of the Canadian Rockies and Selkirk Range Colorado Passes Montana Passes Northern New Mexico Passes Utah Passes Wyoming Passes.
