The classic geological study of the Grand Canyon, commissioned by the fledgling U.S. Geological Survey, is admired today as much for its literary qualities as for its scientific value.

Literary histories, of course, do not have a reason for being unless there exists the literature itself. This volume, perhaps more than others of its kind, is an expression of appreciation for the talented and dedicated literary artists who ignored the odds, avoided temptations to write for popularity or prestige, and chose to write honestly about the American West, believing that experiences long knowns to be of historical importance are also experiences that need and deserve a literature of importance.

Discusses the natural history, geography, and geology of canyons, and offers advice on hiking, rappelling, and rafting, as well as, how to train for an expedition.
