First up - mountain Western House Wren in snow brush by camp at 4 p.m.

June 30 Have come with family up Viola trail towards Brokeoff Mountain, and now (12:30) we are lunching at first snow - only meagre remains of drifts - at rock slide, about 7500 feet, where I found conies on the 17th. Now, I hear them in two directions, close by, but have failed to see one. The day is perfectly clear, and the sun beats down perfervidly. The trees about me are: red fir, predominating; hemlock, a few; mountain pine (P. monticola), more. The "chaparral" is: scattered flat mats of arctostaphylos nevadensis and scrawny chinquapin; most of the ground is perfectly bare of living vegetation. What sounded like a veritable troup of Crossbills flew overhead a while ago - at least there was a chorus of sharp "chup-chup's"; I caught sight of just two birds thru the trees, in undulating, linnet-like flight. Other birds seen ^^{or heard here} the past hour (now 1 o'clock) have been: Hammond Flycatcher, Ruby-crown Kinglet, Solitaire, Audubon Warbler, Western Tanager, Calliope Hummer,^ ^{Mountain Chickadee, Rock Wren,} Clark Nutcracker. I consider this extreme upper Canadian zone.

At about 6500-foot level, saw two Callospermophilus chrysodeirus, the only two ground squirrels of this species
