Historic Trails in Idaho

The Snake River crossing southern Idaho served as a route of travel by native Indians for hundreds, if not thousands, of years. Early fur trappers followed the river, attempting to carry their goods in dugout canoes in the early 1800’s. As missionaries and emigrants began to travel across the country, they also followed the south side of the Snake River across much of the state.
