then by the man on foot following the telephone wire,
as we have done. We are now leveling at about
8000 ft., close to the south base of Brokeoff proper.
We are in plain view of the lookout house on the summit,
not yet occupied this year. The snow is abundant
all about us, vastly more of it than last May at the
same level. Indeed we found difficulty in finding
a bare place, or a ridge, where we could be dry and
avoid the intense glare of the sunlight from the snow.
We are in high Canadian zone, getting into Hudsonian.
The trees close about are red fir (predominantly),
mountain pine, and alpine hemlock. The trunks and
larger branches of the bigger trees are heavily
festooned with a brilliantly yellow-green lichen, betokening
much misty weather here. The forest floor appears to
be bare save for low mats of arctostaphylos nevadensis
on ridges and sunny places. The snow is melted
away from the bases of the trees, but lies between the
trees in heaps 2 to fully 6 feet deep. There
are the usual summer clouds about; the sun
beats down hotly, but the air is chilly whenever
the sun is covered. I kept pencil census of
all birds seen and heard for the five hours,
7-12 (see accompanying sheet). Some arriving
here (at 12) till now (12:45) I have noted:
Solitaire (one singing extatically among tree-tops, or
giving the "barn-door creak" note at spaced intervals,
many in slow sequence); Canada Nuthatch (I hear
