The main access route through Chinle Valley is the north-south traversing of
U.S. Route 191 (US 191). For Arizona,
Chinle, Arizona is located adjacent the valley's southern terminus, and is also the location of the outflow of Chinle Wash from
Canyon de Chelly. Just north on US 191 lies
Many Farms, Arizona, where Navajo Route 59 terminates. Route 59 comes from the northwest, east of
Kayenta, and follows the northeast flank of the
Black Mesa.
Round Rock, Arizona is just north on US 191, but easterly on a site neighboring Lukachukai Creek, (and east of
Agua Sal Creek), both southeast tributaries to Chinle Wash. Continuing north,
Rock Point, Arizona (just northeast of Plane Rock, ), is near the Chinle Valley center, and on Chinle Wash; three routes converge in the Rock Point region, Navajo Route 35 (and Route 5040) are east, Navajo Route 8070 comes from the southwest, from the region of Trading Post Wash, and the north of Carson Mesa, (a section of the southwest of Chinle Valley), and Navajo Route 18, from
US 160 to the northwest. The north terminus region of Chinle Valley is the site of
Mexican Water, Arizona; it lies between US 191 on the Utah–Arizona state line, and US 160 adjacent south. US 160 traverses east-west through the north terminus region of Chinle Valley. In the west, the route turns southwesterly and follows
Laguna Creek which parallels a due-southwest trending section of
Comb Ridge, of both northeast Arizona and southeast Utah. In Utah, US 191 leaves the north terminus area of Chinle Valley (Mexican Water region), and follows the
Chinle Creek course at its east (Nokaito Bench), and intersects
US 163, near
Bluff. ==References==
