Description

As I was walking up the entrance to the trail, just after crossing the dry creek, I spotted this adult rattlesnake in the middle of the trail. I stopped and watched it for a good 10 minutes as it basked in the sun. It knew I was there. It looked at me briefly, then slithered away. Beautiful.

Description

This snake was stationary on the side road leading to Encino Reservoir off of "dirt Mulholland," but he began heading for cover as soon as I approached to take a photo. The pictures aren't great because of low light and the snakes refusal to pose.
