Rattlesnake bite

Story and graphic pictures:

On July 21, 2002, just after my 13th birthday, I was bitten by a Northern Pacific rattlesnake (the snake was originally identified as a Western Diamondback rattlesnake, but that species is not found near Yosemite). I was located on a trail in a hiking area near Yosemite National Park, California. The bite occurred when I was sitting on a small boulder at a distance of 4.5 miles from the trailhead with my cabin group at camp. I had my arms dangling at my side, and a 5 foot long rattlesnake bit me in the middle of my left palm.
