Mining operations and remote homesteads dot the high country of the Roosevelt National Forest in the early 1940s. The landscape is defined by the steep drainage of South Boulder Creek, where the Denver and Salt Lake railroad winds through the canyon floor. Local industry is anchored by the extraction of tungsten, evidenced by the named settlement of Tungsten and the Manchester Mine near Rollinsville.
