Another cutoff to the Armijo route of the Old Spanish Trail had developed before 1844, where the trail forked northeastward from the Mojave River and Mohave Trail, east of what is now Yermo, California, running up Spanish Canyon over Alvord Mountain, to Bitter Spring, then through Red Pass to join the Armijo route near Salt Spring in the Silurian Valley. Frémont also used this route in 1844.: The fork of the trails there on the Mojave River, later became known as Fork of the Road.
