Such a beautiful landscape, you forget how harsh it was for natives and settlers. The desert is composed of stratified layers of easily erodible siltstone, mudstone, and shale. These fine grained rock layers contain abundant iron and manganese compounds which provide the pigments for the various colors of the region. Thin resistant lacustrine limestone layers and volcanic flows cap the mesas. This unique geology is also responsible for the nearby Petrified Forest.
We also were able to visit pre-historic remainsn of dwellings and view ancient petroglyphs.
