The Granite Wash Pass has been a route between the Colorado River and the interior of Arizona from November 1863 when teamsters Gird and Sage discovered a route what became the La Paz - Wikenburg Road through Granite Wash Pass . In the early years a waterhole , Granite Water existed within the pass . The maps of the route in later years , Granite Water is no longer mentioned . Perhaps it was insufficient or had dried up . Granite Water might have been a temporary spring or waterhole created for a few years as a result of the extreme rainfall in Arizona by the storms that caused the Great Flood of 1862 . Also stations for the stage lines like the one at Desert Station and the original watering place at Flint 's had developed wells that provided more water . Today the pass contains the Arizona and California Railroad line , as well as U.S. Route 60 in Arizona from Hope on the west side of the pass and Harcuvar , Arizona on the east
