I found this rattlesnake tail under a bush along the trail.
(Ed R. Levin County Park)
Who's that camouflaging so well with that rock? A rattler! My first time seeing one in NorCal! Was very excited to see him! He was sitting right off of a trail, and he was very still while me and my classmates ogled at him.
Slithering off FAST into the grass at the edge of the trail. Was able to observe it enough to confirm this ID.
Quite small
