Arizona's Swift Trail Parkway, State Route 366, climbs 28 miles up Mount Graham from about 3,200 to 10,720 feet, connecting US 191 south of Safford. The first 22 miles are paved; the remainder is dirt and needs a high-clearance vehicle. The road is named for T.T. Swift, the Coronado National Forest's first supervisor, and was improved through the 1920s before Civilian Conservation Corps crews completed much of the modern route during the Great Depression. Mount Graham itself was named in 1846 by Army topographer Lieutenant William Emory during the Mexican-American War, for his fellow officer James Duncan Graham. Heliograph Peak, visible along the route, served as a signal outpost during the Army's later campaigns of westward expansion. The mountain's forests are the only home of the endangered Mount Graham red squirrel, and the road, designated an Arizona Scenic Byway in June 1992, is the primary way to reach the mountain's cool high-elevation forest from the desert floor below.
