Here, we consider the origins of polygons in the crusts of salt playa and salt pans. These beautifully regular features, a meter or so in diameter, have a worldwide distribution and are important to the transport of salt and dust in arid regions, yet there has been no convincing mechanism known for their formation. We present the first evidence that they are… CONTINUE READING
