I should be very ashamed to admit this, but until a few years ago, I had no idea that Hetch Hetchy, a valley flooded to create a reservoir, was in Yosemite.
Growing up in the San Francisco Bay Area, I knew of Hetch Hetchy. I’m not that ignorant. But I thought it was some reservoir just outside the city. In my head, it was behind a high school right off Woodside Road in Redwood City.
