Mile 31.5 - Stanton's Cave
In 1889 Robert Brewster Stanton, chief engineer of the of the Denver Colorado Canyon and Pacific Railroad Company, stashed his boats and supplies in a large cave after three men (including financier Frank Brown) drowned in the days leading up to this exit from the canyon. The purpose of the expedition was to survey the river corridor, with plans of constructing a rail line capable of transporting coal from the mines in Colorado, through the Grand Canyon, to California. In 1890 Stanton was back again to complete the survey. He and his men found the boats and supplies from 1889 to be in serviceable order, save some minor rodent damage
