Image 6. Hetch Hetchy Reservoir, a man-made lake in Yosemite National Park, with black bears. The gray color of the cliffs is mostly due to lichens growing there, and the "bathtub ring" above the water shows where the lichens don't grow. Hetchy Hetchy Valley used to be comparable to Yosemite Valley in beauty
until they damned it.
