Wolfeau 1938 June 20, (cont.) 4 mi. SW Prineville, 3300 ft., Crook Co., Ore. drove to a point on the cliffs about 3 mi. by air-line S of camp. I set 5 rat traps and 20 mouse traps among the rocks about 10-20 ft. below the top of the cliffs. There was grass and dead wood present. Evidence of rats was droppings, urine, and nest material but now appeared fresh. Around the cliffs was seen: a bat; 2 Surley Vultures. While driving tracks to camp, a Horned Owl was seen and collected by A.H.M. June 21, drove out to traps with F.T. and had caught: 1 House Mouse; 4 Peromyscus maniculatus, 2 of which were immature. No rats were caught by F.T. or myself. Saw a Sparrow Hawk (caught by A.H.M.) in the morning and in the afternoon we drove camp. On route to new camp near Bend in Cascades drove through Prineville to Bend and out toward Century drive to Resclutes
