Journal Page 2. Feb.15 Left Berkeley at 7:10 AM to Shelton F. (Jerry) Cook, Jr. for Panoche. Route via Walnut Creek, Coral Hollow Rd., (from just E of Tracy), hence via rt. 33 through Gustine, etc. to Mendota. Birds seen were the usual. Numerous yellow-billed magpies seen near Gustine. One bird seen with nesting material in hill. On small pond 14 mi W of Volter (on Rt. 33), Merced Co., saw 6 whistling swans with numerous coot and Red-Dees. Stopped at Dos Palos for gas, coffee, and shells at about 9:50 AM. Proceeded south of Mendota to point on rt. 180 hence east toward Fresno. At locality 0.3 mi E of point rt. 180 and road to Tranquillityace stopped and put traps. I had 80 museum specials and live traps. Cook 101 M. specials. This area flat, numerous pools of water in shallow depressions. Abundant signs of Gaps and smaller rodents. Ground covered a short 1"-2" rug. green vegetation & scattered low (6"-15") bushes. Horned larks abundant killdeer and meadowlarks also common. At about 12:45 returned to Mendota & store, then headed South and West toward the valley of the Panoche Creek. We drove part way up along the road that connects the San Joaquin Valley with the Panoche Valley (S.E. end of Panoche Valley) since this road marked closed for winter we didn't go all the way up. Stopped at location where Drinnell and Russell trapped Dipodomys ingens in 1932 (at 1 mi S.W.of BM 502). We failed to find any signs of these animals. Went back along road we had taken over from Mendota to point 4.mi. N., 8 mi E of BM 502 and set traps for Dipodomys ingens. I made 8 sets in burrow entrances as Drinnell and Russell has done. Cook put out 3 live traps. Citellus nelsoni also seen at this place. This area is about 1/2 mi. from the hills and on a very gentle slope, but before the cultivated area of the valley. Soil fine, silty, veg. just about 6" high. Returned to vicinity of BM 502; forded Panoche Creek due and drove North, across uncultivated land covered dry short vegetation and scattered low bushes. Several Citellus nelsoni seen. This road ran off this gentle slope into isolated cultivated land before reaching point with road from Mendota to the little Panoche Creek.
