That is going to be an amazing sight. No clue how they can do it but would love to see a video of the flood.

On Sunday I was up on Donner Summit and was thinking that the conditions were more appropriate for backpacking with nothing more than microspikes and a few extra layers than they were for snowshoes and a full winter rig. The PCT at Castle Peak was a wet mess. The snowpack is still horrible.
