A. Good 1980 Journal Berkeley to Sagehen Field Station, Nevada Co., Calif. 3 Oct. The Mammalogy class field trip to Sagehen left Berkeley ca. 1030 and followed the following route: I 80 from Berkeley E to Truckee, then N on Cal. 89 7.9 mi. to a dirt road on the left leading to Sagehen. 1.7 mi. along this dirt road to the station. We arrived at Sagehen ca. 1430. At ca. 1630 we split into groups of 2 and went out to set out our traps. Judy Gradwohl + I set out the following traps between 1630 and 1830: 1.9 mi. W Sagehen - 6 museum specials along a stream among willows + alders + in a greasy meadow and 24 museum specials and 1 Victor rat trap along a transect through the lodgepole pine - white fir- incense cedar forest at approximate 30 ft. intervals. Kiln meadow, 0.9 mi W Sagehen - 19 museum specials in Microtus runways in a large open field. 0.6 mi W Sagehen - 11 museum specials and 2 tomahawk live traps [illegible] and along the edge of a large pile of rocks. All traps were baited with mixed peanut-butter and oats. We then converged on Sagehen, had supper and had a lecture from Jim Patton on various trap types. Between 2200 and 2330 that night we went out to check our traps. The temp. that night dropped below freezing though, it was not that cold when we checked the traps. The moon was new. The results of this circuit of our trap line [illegible] amounted to 1 Microtus montanus (JG 3) + 1 Eutamias speciosus (DAG 244). We reset the traps that had been sprung and returned to Sagehen where I prepared my chipmunks. We turned in sometime after midnight.
