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.
