Painted Desert (Arizona) plateau's south border the Mogollon Rim, the north border of the Arizona transition zone. Owing to the strong rain shadow of the Mogollon Rim, the Painted Desert has a cold desert climate (Köppen "BWk"), with hot, dry summers and cold, though virtually snow-free winters. The annual precipitation is the lowest in northern Arizona and in many places is lower even than Phoenix. Much of the region is accessible only by foot or unpaved road though major highways and paved roads cut across the area. The towns of Cameron and Tuba City, both on the Navajo Nation, are two major settlements.
Mu Us Sandyland name—for example, a map in Julia Lovell's book "The Great Wall: China Against the World 1000 BC–2000 AD" shows the Ordos Desert only in the portion of Inner Mongolia, which lies south of the Yellow River. Several research papers cited below claim that the Mu Us Sandy Land includes part of Shaanxi and Gansu. A clear delineation of the area is still needed here, based on multiple sources. The Mu Us Sandy Land of north central China lies at 37°30'–39°20'N,107°20'–111°30'E and covers 40,000 km. As part of the Ordos Plateau, the elevation ranges from 1,000m to 1,300m (as low as
