Native attacks increased significantly after 1860, when most of the army troops were withdrawn, and miners and ranchers began fanning out all over the country, often encroaching on Native American territory. Increased attacks along the Humboldt led to most travelers' taking the Central Nevada Route. The Goodall cutoff, developed in Idaho in 1862, kept Oregon bound travelers away from much of the native trouble nearer the Snake River. Other trails were developed that traveled further along the South Platte to avoid local Native American hot spots.
