2 15 7-24 July 1979 Kept us indoors (in the Scout) almost all day. Set 30 Muskrat Special snap traps baited with Peanut Butter and Quick Rolled oats, up the narrow rocky canyon N of camp. Rained at night. Heard a Screech Owl. 21 July 1979 results of last night's trapping: 2 Peromyscus (#105, 106). Many of the traps had been set off by the rain. One caught a Newtowna by the tail. The rat dragged the trap much of the way under a boulder, than managed to slip the skin off the tail, so I found the tail skin in the trap. After prep'ing the specimen, we set off on our packing trip. A rugged uphill climb with 40 pound packs for two hikers in rather poor shape. We collapsed about 1/2 way to our goal, atop a ridge 13/8 mi E and 1/4 mi S of Grapevine Peak (7840'). Saw considerable Horse sign and some Deer sign over much of our route and around our campsite. Set 24 snap traps, baited with peanut butter and Quick Rolled oats, in a line through our campsite. Beginning on a rocky outcrop, then up a small ridge, down the steep otherside of it. Habitat essentially similar to the area around the windshaft. It did not rain this night.
