Pants, Sean 2006 Journal June 21 Area east of Eagle Lake, Lassen Co, CA Craig Norris, Jim McGuire, Chad Martin and I drove to Golding and stopped to survey the area near Pine Creek where mammal trapping had been done (40.66074°N, 120.79124°W [WGS84, 6m acc.], 1576 m elev.) on the W side of Golding Road. The area had yellow pine, sagebrush and lava rock. We searched from 11:00-11:35 and caught S. occidentalis and S. gracilis (13 total, to get Jim's catalogue numbers). We drove around to the north end of the lake and stopped in an area with sandy soil, sagebrush and grass in full sun. We searched for about 20 min in the sandy and rocky areas but got only 1 female S. gracilis at 12:10 on sandy rocks (JAM6 - 40.58896°N, 120.78606°W [WGS84, 10m acc.], 1569 m elev.); we saw many more S. gracilis. We then turned south on Hwy 139 and stopped 1.6 mi S of the intersection with AI (JAM 7). We searched up the rocky slope covered with sagebrush and juniper from 12:55-13:35 and caught 2 S. occidentalis. Chad found a dead Masticophis tarasius with its head on a rock, but we didn't collect it. We stopped 13.1 mi S of the intersection with AI to collect a roadkilled C. constructus at 14:20 (JAM 8) and then drove east of Susanville on A27. We went up Word Lake Rd for 1.9 mi N and searched between (40.41970°N, 120.42339°W [WGS84, 6m acc.], 1300 m elev.) and (40.42434°N, 120.42543°W [WGS84, 6m acc.], 1285 m acc) between 15:45 and 17:30. The area was flat with sagebrush and very dry, with no trees. There was a ditch bordered by two rock walls. We caught several S. occidentalis on the rocks as well as 3 Crotaphytus viridescens. We then caught 4 Gambelia wislizenii including a gravid female. Chad saw 2 Aspidoscelis tigris but
