J.G. Hall 1954 207 July 21 Sageshen Creek, 6500 ft., 3 mi. NW Hobart Mills, Nevada Co., Calif. R'slide first real proof that a beaver freely travels substantially up & down from the gap in the blasted dam which I'd previously sus- pected might form some kind of a terri- torial boundary. The skinned areas on back of shoulders and head were plain & unmistakable but I could see no mark on the tail. At about this same time a small one appeared between the ends of the blasted dam but was lost. 8:30 small one near side disappeared, re- appeared, then dove into lodge. This one seems to have what looks like a big fly sitting on his head between but a little posterior to his eyes: This may or may not turn out to be any good as a field July 22 mark. Left 8:35 P.M. Up early to check traps since last night was v. cold. No luck. Spent all morning showing Don Cornelius, Gerald Geraldson & Mr. Williamson of the FS, Bob Hoffmann's trap lines. In afternoon made signs for traps & set all 4 just before supper. By 8:30 temp. was as low as it had been this time last night so I went July 23 down & set hooks on the traps. Checked point of willow strips and couldn't locate: N stake for B, M for C, M for E, N for E, M
