The Navajo Indian Reservation of northern Arizona and New Mexico has undergone large scale desertification as a result of sheep and cattle grazing and subsequent wind erosion. As a result, infrequent heavy precipitation such as that pictured here has easy access to erodible shales, resulting in dramatic sheet and gully features and the exposure of dense deposits of Triassic fossilized wood. It is ironic that desertified landscapes under very dry climates often display the most striking examples of water-based erosion.
