S.R. MOON 1987 Species Account Speckled Rattlesnake (Crotalus mitchellii) 5 May Two canyons west of Blind Spring, Providence Mountains, San Bernardino co., CA. T 10 N R 14 E sec 29 ne'/4 . elev. ~ 1650 m. I nearly walked over a large grey snake that was basking on the reddish rocks of the east side of a spring in the steep, rocky canyon. The snake was approx. 1-1'1/2 m long, greyish with dark speckles, and an approx 10 segment rattle that had broken at the end and did not taper before the break. It was a very heavy snake, probably also quite old. The dense willows of the spring fill the canyon bottom, the catclaws and chollas on the steep, rocky hillsides around the snake. It was shady on the west side of the canyon and sunny on the east side where the snake was. The snake was still when I approached but then hissed, rattled, and took cover in some dense shrubs as I stood and watched. 1645 PST.
