Eroded sandstone column in a desert. Wind intensity increases around the base of the rock, increasing erosion of the rock and forming a bowl-shape hollow (deflation hollow) in the sand. The flaked appearance of the rock's surface is due to weathering. Photographed in Tin Tarabine, Sahara Desert, southern Algeria.
