(1) 14 19-24 July 1979 Plummer Mine Shaft to Grapevine Peak, with a side trip to Plummer Spring We arrived late afternoon (ca 5 pm) at our campsite near the shaft, and prepared to hike up to the pass to spend the first night of a several day backpacking trip. The weather looked potentially threatening, so we ascended the hill N of camp to get a better view. Rain started before we reached the top of the hill, so we decided to stay in the vehicle for the night. During a lull in the rain, I managed to put out 18 snap traps, going up the ridge S of camp, including sets at several fallen logs and likely-looking rocks. It rained off and on most of the night. Results of 18 trap-nights: (human-spread traps, baited with peanut butter and quick rolled oats): 1 - Reithrodontomys egalotis (#100); 4 - Peromyscus (#101-104). Put up the Reithrodontomys as a skin, and the Peromyscus skinned and preserved with Caltox (+thanks to Keith Grove for the suggestion and material). On the trip in to our campsite, going then across vast flat, saw 10 Jackrabbits, a Mule?, a Burrowing Owl and several heath's Thrashers and Horned Larks. 20 July Rained most of the day and night, mostly a light, misty rain that
