Walking on top of the O'Shaughnessy dam at the Hetch Hetchy Reservoir.
This dam was built to help supply water to the city of San Francisco. It was the environmentalists for example John Muir and the Sierra club versus the developers. The developers won. This took place in the early 20th century, about 1920. Now, there are about seven reservoirs in that area and there's some talk about taking down the dam and restoring the area to its natural beauty. It is a glacial valley similar but smaller than Yosemite valley. With the drought and climate changes, I don't think that's going to happen but at least they're talking about it.
