North America plays host to around

North America plays host to around four major hot and dry deserts, the features of which are quite fascinating. Scouring winds work on the face of deserts, sandblasting rocky outcrops into bizarre shapes and blowing sand dunes along in ever-changing patterns. The deserts dunes of the Atacama blow into patterns like tide-washed sand.

Another interesting feature of these deserts is an inselberg which is a mass of hard rock that resists erosion and stands alone.
