Harold Leich set out on a westward journey in the summer of 1933. His travel narrative details his river trip down the Yellowstone River and the first descent by boat of the upper Colorado River from Grand Lake, Colorado, through Cataract Canyon, Utah. He was the first to push through this entire upper section, running rapids that had never known a paddle, rebuild­ing his kayak along the riverbanks, camping rough, and meeting ranchers and railroad workers in these remote regions. Leich’s sudden change of fortune in Cataract Canyon, in the most isolated part of Utah, and his soul searching as he worked his way out of a perilous situ­ation, will speak to anyone who has ventured beyond roads and trails and faced potential tragedy alone. Alone on the Colorado takes readers on the adventure of running rivers and riding the rails, while painting a unique and optimistic portrait of Depression-era America.
