The Grand Canyon is an immense place, almost unfathomable in scale, and one of the last places in the American West to be explored. John Wesley Powell called it the “Great Unknown,” having no idea what rapids, falls, or canyons awaited him on his first descent of the river in 1869. In the decades since, the Canyon has been a playground for dozens of explorers. River runners, backpackers, routefinders, lithic hunters, and peakbaggers have all laid claim to the Canyon’s iconic landmarks, often seeking out the prestigious “firsts.”
Yet deep within the Grand Canyon remain secret and intimate tributaries rarely visited by man. This is the story of these slots and the canyoneers who systematically explore their drainages.
