The site todayEdit
The site of Impassable Pass still exhibits deep ruts from the passing of the wagons of Mormons, the Forty-niners and later immigrants and the freight wagon trains that used the road from 1855. A large boulder installation exists at the top of the old roadway of the pass into Spanish Canyon, thwarting modern travelers from driving over the ruts, and a rock ring at the top of the pass may be the remains of Mormon signal fires.
