East of Flagstaff, the old Route 66 road is effectively submerged beneath the freeway, which drops down to cross desolate desert, passing through desiccated towns and Petrified Forest National Park. Remnants of numerous old roadside attractions—Native American trading posts, wild animal menageries, and Holbrook’s famous “Sleep in a Teepee” Wigwam Village—all survive in varying degrees of preservation along Arizona’s section of Route 66.
