My partner and I exit the tunnel at Hetch Hetchy Dam on the way to huge Spring waterfalls. In the first patch of sunshine lies a coiled Western Diamondback, and I hadn't seen one in a bit. She's still adjusting to sunlight as I squat in glee. She squints, saying "What is it?"

"Rattlesnake." Instantly her legs acted as if she were climbing a rope ladder to the sky. So she's afraid of snakes, I muse.

Snakes are almost never seen in the Tahoe Basin, or in the High Sierra where we had mostly been together. A couple of more exposure events and she was brave enough for the desert.
