J.G. Hall 1953 122 July 28 Sagehen Creek, 3 mi. NW Hobart Mills, Nevada Co. Calif. up slope to disappear in rocky area & brush. Mistook it at first for large squirrel. V. Rockslide colony 7- 8:45 PM. Hoffmann & I observed till dark but saw no beaver here. Made some reckless setting traps & this may delay their eve. appearance or maybe they just July 29 weren't out there tonight. No beaver caught here when checked this AM. July 30 7 PM left traps unset tonight but watch- ed V. colony till 8, being careful to make no noise on approach--still no beaver so perhaps "reckless" of set- ting traps is of no consequence. Then went down to lower Rockslide where I noticed one beaver here twice or two beavers separately. This was in the area of my most active watching last year. Water higher here and lower in the very lowest part of the colony than was the case last year. This was noticed on June 6. This may be due to better upkeep of the dam just below the submerged "sink hole" & poorer upkeep of the large one built along the giant deadfall farther down. Left 8:45 PM.
