M.F. Smith 1982 JOURNAL Gold Run Creek, 3 mi. S Susanville, Lassen Co., California 4240 ft. Mar. 25 To the other side of Gold Run Creek from this direction, Jim arrived at the fence with the van and we decided to pick up the others and drive the long way around to the other side. We got permission at the Sella ranch but found very little gopher sign—mostly ground squirrels. Jim and I each set out three sets. Dropped Carol off at the motel and went back to Nagel's Reservoir. Set several fresh mounds and caught six more animals in the area before pulling traps at ~4:00 p.m. Then drove over to the other side to pull the remaining traps. Jim caught one gopher at Sellas. I had walked across the creek on the dirt road about Nagel's and set three traps just on the other side of Gold Run Creek. I caught one gopher there. Went back to the motel and processed the seven animals (plus one kept alive). Since there was very little activity in the fields on the north side of the creek we decided we had collected everything we could in the contact zone. Jim decided to use one general locality for all the samples, with individual captures plotted on the topo sheet. My locality for the field next to Nagel's Reservoir will have to be changed.
