Sierragator volunteers with Kern County SAR. In speaking with him a few weeks ago when I was out there for some Death Valley playtime, he told me that a surprisingly large percentage of their SAR deployments are water rescues. I guess many of us, who spend so much time in mountains, tend to forget the dangers that lie lower down the trails.
I've only been in Kings Canyon once, but the ferocity of the stream and river flow astounded me. Easy to see how someone could get swept away in the blink of an eye.
An absolutely horrific way to end a vacation. Thoughts and prayers to the family.
