    Hiking

    There was a lot of controversy around the damming of the Tuolumne River and flooding the Hetch Hetchy valley over 100 years ago. The famous naturalist John Muir held it up as an equal to nearby Yosemite Valley, and though only a few grainy photos remain if definitely looks like he had a point. These days you can still be stunned by the vertical granite walls, dramatic waterfalls, and towering domes.
