The Merced River flowing out of Yosemite. This is the new rapid created by the landslide a couple years ago (the one that made them re-route the road on the other side of the river with two temporary bridges)
The Kaweah just above Dinely Bridge.
next day...
I was holding the camera in my mouth, which worked out great until I pinned on the piton rock at the bottom of the rapid and had to spit it out, push off, and roll up. I definitely need to look into a helmet mount or deck mount for the cam. I was going to add a sound track, but I've been getting good feedback on the sound effects!
