21 Aug Sedgehen Creek, 6500ft., 3mi. NW Hobart Mills, Nevada Co., Calif. Rockslide 9AM. Asp. sample D laid out. S stake is 34' from sta. 25 and 39' from the sample C stake. M stake 7'E of "the" 18" Jeffrey standing alone in the asp. Since there is continuous asp beyond 100' the sample was made 200' x 10' in size, the N stake being 8' W of an old rotting log. Left 11:45, at 2PM. Kingfisher rattling down stream. Willow sample D chosen as "typical" willow working for this colony and, so, for the detail "availability" sample. Live twigs over 1/8" diam (1/2 pencil width) or larger were counted. Clumps A-E were counted but entered - counts on clumps F-L on p. Upper. Left 4:40; at U. colony seat 6:25PM Warm & clear. A couple was fishing ponds when I arrived, the woman said that her husband and had seen a large + a small beaver a couple of ponds up about 6:10. The couple left about 6:50. 7:00 spotted a spike going W thru asp. on N shore + I could see that the left antler was 8 or 10" long but the right one only 4 or 5" long. 7:20 U beaver came up over the main dam at the N end of the dam. Worked on bark at butt end of an almost-dead asp. log in the dam, chewing off the bark. Fur mark doesn't show up so
