The wilderness setting is outstanding, with a relatively undisturbed natural landscape and little human intrusion. The river corridor, with its wide meadows and lush riparian area, is used by numerous wildlife species.

Bailey Creek

Lincoln

From the divide with Little Greys River north for 10 miles into the Snake River

W

G, W

Bald eagles are frequently seen, and known to nest in the lower section near Snake River. The corridor is used by moose and elk, and the lake contains a fish population of fine-spotted cutthroat trout which attracts eagle and osprey. Ducks and other waterbirds use the lake for nesting and feeding. Bailey Lake, originally a small glacial pond, was greatly enlarged by a massive landslide that continues to build a natural dam at the lakes outlet. The landslide and lake are examples of surficial geologic action that have potential for interpretation.
