J.G. Hall 1953 July 26 Sagehen Creek 3 mi. NW Hobart Mills, Nevada Co, Calif. saw colony. Judging by the old low cuttings & high winter cuttings I'd say this colony had been in ex- istence since early last fall. Large- st dam horse-shoe shaped. Work- ings go clear up to the stream- side shelf. Upper Falls slide col- ony 7PM set out a beaver trap a N end of main dam. Spring camp 10 PM surprised a bear get- ting into our garbage & sugar can and chased him up the hill a couple hundred yards. Came back in about 1/2 hr. so chased him away again; he was a medium sized brownie. About 11PM heard what I think must be marten on our tent roof. Also heard mice but too big for a mouse, about like a heavy July 27 squirrel. Bear had torn up the spring getting a gallon of milk & messing things up generally. Caught no beaver but reset in same place in evening. July 28 Road 1/2 mile down from camp 5 PM, saw marten run across road &
