M.F.Smith 1982 JOURNAL Susanville, Lassen Co. California Mar. 21 Maria Gloria Basañez and I took the Trailways bus from Oakland to Sparks, Nevada. Met Jim and Carol Patton at the Nugget in Sparks and drove from there to Susanville. We plan to collect in the zone of contact between Thomomys bottae paratilis and Thomomys townsendii relictois in the area around Gold Run Creek. Mar. 22 Gold Run Creek, 3 mi. S. Susanville, Lassen Co., California, 4240ft. Drove out from Susanville to get permission to trap in the contact area. Stopped at a house on Richmond Rd. and found out the owner of the property lived farther so drove to their place - Happy Valley Ranch, owned by the Nagel family. Got permission to trap and a key to the gate on the dirt road leading into the property. The dirt road shows on the topo map (GHI Diamond Mtn. Quadrangle 7.5 minute series) just south of Gold Run Road, leading off of Richmond Rd. past Nagel Reservoir. Parked the van at a large shelter for hay bales and split up to set traps. Carol and I set between the van and the road, Jim and Maria Gloria set farther up the creek. Jim Nagel came by in the afternoon and I rode with him to see another possible field to set in next to Nagel Reservoir. He also got permission for us to trap the neighbor's field on the other side.
