I was just in Yosemite this week and heading back again tomorrow. Yosemite Falls is completely dry. I'm wondering if there are any 'secret' routes that are only possible to climb when the waterfall dries up.
Maybe this happens so infrequently that no one has tried? Is it possible there are some good first ascents right there hiding behind a waterfall?
Via Sin Agua is sort of famous. Pretty sure it's in the Reid Big Walls book. Can you imagine going up there with a clear forecast and then having some afternoon thunderclouds move in on you? Or if it just started raining miles away in White Wolf or something. You'd drown in your harness.
