Colorado's Black Canyon, the nation's newest National Park, is steeper and narrower than the Grand Canyon. There are many places where dangerous rapids fill the entire space between the walls. The Black Canyon was not conquered until 1901 when William Torrence and Abraham Lincoln Fellows completed the first full passage of the canyon using a rubber boat for some portions of the trip. Robb Magley traces the unique history of the Black Canyon, but not content with archival research, the author and a friend took their own adventure on foot through thirty-three miles of the narrow canyon. The adventure required seventy- six river crossings and almost cost them their lives.?We had no food, and no way to purify drinking water. The sun was going down, and we had nothing but shorts, t-shirts, and life jackets to keep us warm. The only piece of gear either of us had left was our river knives, clipped to our life vests in the event we had to free ourselves from a fouled rope. The canyon was getting darker, and we had run out of options.?
