Upheaval Crater,Utah,USA,satellite image. The area shown is about 5 kilometres across. There are several theories that attempt to explain how this crater was formed. The most widely accepted theory says that it was formed by a meteorite impact some 60 million years ago. The current appearance of concentric rings formed as erosion revealed the layers of sedimentary rock tilted upwards by the impact. The blue ring is a white sandstone called Permian White Rim Sandstone. The cliffs around the central area are over 400 metres tall. There is a road at upper left.
