Greene, H. 1988 August 3 Bufo cognatus, Scaphiopus couchii, and S. (continued) multiplicata (several of each) and a large, freshly flattened Pituophis melanoleucus. August 4 Sunny and partly cloudy this morning. From ~11:30- 15:30 hr, Missy and I walked a 2 1/2 mile trail that ends at Herb Martyr Dam and begins at a point on the road to that dam called Greenhouse Trail. We saw Sceloporus jarrovii and S. virgatus, a golden eagle, a fresh fox scat and several possible bear diggings. A few hundred meters past Ash Spring the trail crosses a small stream, and a few meters farther on the left (north?) is a large (~3m) log with most bark gone. On the underside, a few cm above the ground, I noticed what later proved to be an small adult F Crotalus molossus - at first I saw only the yellow posterior and black tail (was she thermoregulating with it?). Getting closer I saw her head facing out of the crack - she was between a finely attached piece of thick bark on the underside of the log. She moved out of sight despite my efforts to hook her out, and I at first thought she went into the very deep leaf litter under the log. Spotted her back in the crack and after considerable poking got her crawling out a side hole. There was continuous sizzling from the time I first touched her with the probe. At that point I could see her crawling out, and noticed another blacktail's head
