This view of White Pocket at dawn, in the Vermillion Cliffs National Monument in Arizona in the Southwestern part of the USA, illustrates why it is called 'White Pocket". A pocket in this case is a small area of land that is different from what surrounds it. The white Navajo sandstone formations, which began to be carved out during the Jurassic period by water and wind erosion and compaction out of sand dunes, are different from the surrounding landscape of sand and sagebrush.
