Sand Dune Expansion

Sand Dune Expansion

On the Arizona portion of the Navajo Nation, recurring drought and rising temperatures have accelerated growth and movement of sand dunes. Map above shows range and movement of Great Falls Dune Field from 1953 to 2010. Moving and/or growing dunes can threaten roads, homes, traditional grazing areas, and other tribal assets.
