Coal Mine Canyon
, on the Navajo Reservation of north Arizona, is a wide drainage bordered by cliffs up to 500 feet high, part of which form isolated spires, hoodoos, thin ridges and narrow gullies. The hoodoos are relatively few in number, but tend to be tall, multi-colored, and complex, containing differently-textured components. The rock layers are colored black (coal), white, and various shades of red, yellow and grey. The drainage system is long and branched, but the best section seems to be the uppermost end, just half a mile from Hwy 264, reached by a short side track.
