Blue Canyon is a lengthy, cliff-bound section of Moenkopi Wash in northeast Arizona, part of a branched drainage system that also includes Coal Mine Canyon, Ha Ho No Geh Canyon and Bat Canyon, all cutting into soft, multicolored, sedimentary rocks on the east edge of the Painted Desert near Moenkopi. This remote, uninhabited region spans the border between the Navajo and Hopi reservations, and has become more well known in recent years owing to the incredible array of badlands and eroded rock formations, impressive on both large and small scales; from colorful, sheer-walled ravines with convoluted walls, to tiny hoodoos and innumerable other intricate forms.
