Named for William H. Hamblen (1878-1952), who in the 1890s pioneered a crude road (about 6 mi. N) into Palo Duro Canyon along old Indian trails. This cut 120 miles off settlers' trips to the courthouse in Claude, but was steep and dangerous. Hamblen and his wife, Ada (1883-1955), ranched near Wayside after 1905. He worked unceasingly to get a passable road through Palo Duro. Elected county commissioner in 1928, he at last had a graded road built. By decision of the commissioners court, the road was dedicated in 1930 as Hamblen Drive. With its paving in 1954, a dream of a lifetime was realized. (1968)
