"When beginning our hike my friend Danny and I saw a rattle under a tree. I took a couple of photos. It still alive, not rattling but it would open its mouth and move (pretty awesome).

"On our way back (about 45 min later) from the hike we decided to look under the same tree the rattle was in to get better pictures. We found it but discovered it had been pulled into some nearby bushes by a California Snake ! It was now eating the rattle as its dinner."
