Fish taken include grayling, rainbow trout, Dolly Varden, char, lake
trout, whitefish, suckers, and bull trout.

The most common amphibian is the northwestern toad, which was
encountered in all parts of the area, including dry pine terraces and hot
talus slopes; one individual was found near the summit of one of the higher
peaks, 2,500 feet above the nearest alp meadow. Frogs appear confined
to muskegs and small streams and lakes below an elevation of about
4,000 feet.

Mosquitoes are most numerous from late May to the middle of
August and black flies from late June until September. ‘Bulldogs’ and
several types of deer flies are a serious nuisance to horses in the early
part of the summer.

INHABITANTS

The area has no permanent inhabitants. One Indian family from
the Bear Lake settlement to the west frequently winters at Aiken Lake.
Five different trappers have parts of their trap lines within the area, so
that many of the main valleys contain cabins spaced about 1 day’s travel
apart. Camps at several of the prospects have been occupied at different
times for periods of as much as 5 years.
