days from Summerville to reach the head of Grizzly Creek, the 

 night of July 19 being spent at Hunters' Camp. 



Hunters' Camp, used by hunters and eattle men, is situated 

 about a hundred feet down on the southern slope of the divide 

 between Salmon River and Grizzly Creek, in a grove of white fir. 

 The slope down to Grizzly Creek is very steep and the underbrush 

 of chinquapin and eeanothus dense. There is a good spring coming out 

 just below the camp, and its downward course is marked by dense 

 alder clumps. Mr. Hinz says he often comes up on this ridge during 

 the winter to trap, and lias caught several fisher here. 



The trail up Grizzly Creek from Hunter's Camp had been blazed 

 years ago by a government surveying party which had made the 

 ascent of a peak next to that known as Thompson Peak, and con- 

 sidered the highest point of the Salmon Range. We were unable 

 to ascertain the name of this peak from any of the people in the 

 region, and it is not given on the maps, but is so close to Thomp- 

 son Peak and so nearly of the same height that for the sake of 

 convenience it also may be called Thompson Peak. 



Grizzly Creek has as its source a fair-sized lake lying in a 

 rocky bowl between the mountains, and fed by great snow banks. 

 The outlet of the lake is a waterfall which makes a sheer leap of 

 about fifty feet over a rocky wall, and then by a succession of 

 smaller drops descends into Grizzly Canon. Our camp was just 

 at the base of this precipice in a clump of red fir, white pine, and 

 hemlock, flanked by large open meadows and willow thickets. 



In scenic beauty this spot surpassed any of our other camping 

 places (see pi. 17, fig. 5), but collecting was rather arduous on 

 account of the ruggedness of the ground and the steep slopes, 

 either up or down; for the canon is hemmed in on all sides, except 

 in the direction of its outlet, by rocky walls. Small mammals were 

 not particularly abundant, and Mr. Hinz attributed the lack of 

 marten and fisher sign to the absence this year of suitable food, 

 especially chipmunks. Aplodontia sign was abundant in a small 

 canon where a stream and alders provided their favorite habitat 

 (see pi. 16, fig. 3), and Zapus and flying squirrels were secured. One 

 deer was shot high up on the crest of the mountain a thousand 

 feet above camp. Save for elusive thrushes which sang in the 

 underbrush, birds were rather scarce right around our camp. The 

 density of the tree growth probably accounted for this. In the
