Railroad Canyon, Don Pedro Lake

Railroad Canyon is a 400-foot deep steep walled narrow Serpentine rock canyon cut through by the Tuolumne River and flanked by seasonal waterfalls. The 68 mile long Hetch Hetchy Railroad, that was used to construct the O'Shaughnessy Dam that submerged the Hetch Hetchy Valley of Yosemite National Park, once ran through this canyon. Now the old railroad itself is submerged under 150 feet of the New Don Pedro Reservoir.
