I was in Owens River Gorge last week, it's a very interesting place. It has some of the tallest single pitch rock climbing in the world, sometimes requiring 80M ropes: https://www.mountainproject.com/area/105843226/owens-river-g...
Not far away are the world's most photogenic boulders, the Buttermilks, and when I visited (from Canada) I was surprised to find that the boulders are on LA municipal property and the pipe that takes Owen's River's water over the Sierras is nearby.
