1. Emigrant Trails Marker
In 1859 F.W. Lander's wagon road builders dug and improved grade that shows more clearly. California traffic, for which Lander constructed a better road, diverged from this Snake River route to Oregon just beyond Raft River, 6 miles west of here. When they got up this grade, emigrants were thankful that they had passed 20 miles of bad road, and that a less demanding trail lay ahead.
Erected by Idaho Department of Transportation. (Marker Number 339.)
