Early history

The Bitterroot Mountains presented an unexpected, formidable obstacle to Lewis and Clark during their expedition westward, and ended their expectation of finding a "Northwest Passage" giving an easy connection from the Atlantic watershed to that of the Pacific.

Bitterroot controversy

Swanson (2011) examines the critical role of Guy M. Brandborg of the U.S. Forest Service, who was supervisor of the Bitterroot National Forest from 1935 to 1955. By insisting on selection cutting, he tried to protect the watersheds and wildlife habitats that are harmed by clear-cutting. After he retired in 1955 Brandborg denounced the Forest Service for deviating from his model. He launched a public attack, known as the "Bitterroot controversy". Brandborg lobbied to secure passage of the National Forest Management Act of 1976, that codified his model.
