Granite Wash Pass is located at the southwest end of the Granite Wash Mountains and the northwest end of the Little Harquahala Mountains.
[1] 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.
[2] The maps of the route in later years, Granite Water is no longer mentioned.
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.
