Greene, H. 1989 June 6 (continued) To check its morning behavior. From ~1/40 - 2/15 hr I drove from Portel to the Sistrums site and saw no snakes. Bessiey Timberlin and Tony Snell picked up a Microceroides eurygnathus during that period, hit by a car in front of them. Two nights earlier they saw one Pituophis and Crotalus scutulatus on the Portel Rd. June 7 With Bessiey and Tony, checked the Crotalus molossus at 0850hr, when the slope has been in full sun for several (>=3) hours. We could only see the edge of a coil, deep in the hole. Then Tony took me high above on the steeper rock face to the winter sites. Two holes the snake used are now plugged w/dirt and litter - if that is typical, a snake using this slope can not depend on a particular hole - but of course there are many holes. In fact, our snake used several over the course of winter, some of them more than once on different occasions. After lunch Claudia and I drove up to the slide, just before the turnout to Barfoot, where I've caught Crotalus molossus and C. pricei in the past. Everything is exceptionally dry and the soil among talus everywhere exposed - at first I wondered if the Forest Service had run some huge machine over the area! Saw only a few Sceloporus janovii, adults and hatchlings. Went to Barfoot campground (now filled with Boy Scouts) for photos of the slide, and also saw several S. janovii there. Drove back via E.
