THEMIS: More Siton Undae

Winds of Siton Undae (THEMIS_IOTD_20140527)THEMIS Image of the Day, May 27, 2014. Today’s image shows another section of Siton Undae. There is a crater just off the image to the left (west). In the lee of this unnamed crater there are no dunes, but there are numerous dust devil tracks. Dunes surround the crater, except for the lee area. The winds, moving from west to east, are channeled into a chaotic regime by the crater rim, which has created the dune-free area and the dust devils.
