Granite general, descriptive field term for lighter-colored, coarse-grained igneous rocks. Petrographic examination is required for identification of specific types of granitoids. The extrusive igneous rock equivalent of granite is rhyolite. Granite is nearly always massive (i.e., lacking any internal structures), hard, and tough. These properties have made granite a widespread construction stone throughout human history. The average density of granite is between , its compressive strength usually lies above 200 MPa, and its viscosity near STP is 3–6·10 Pa·s. The melting temperature of dry granite at ambient pressure is ; it is strongly reduced in the presence of water, down to
Granite Wash Pass Granite Wash Pass Granite Wash Pass is a gap between the Granite Wash Mountains and the Little Harquahala Mountains, in La Paz County, Arizona. Granite Wash Pass is located at the southwest end of the Granite Wash Mountains and the northwest end of the Little Harquahala Mountains. The apex of the pass is at an elevation of 1,834 feet/559 meters. 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.
