About this image

Siton Undae is a large dune field located in the northern plains near Escorial Crater. Siton Undae is west of the crater and is one of three dune fields near the crater. The other dune fields are Hyperboreae Undae and Aspledon Undae. The nearby north polar cap is dissected by Chasma Boreale, which exposes an ice free surface that may be a source of some of the sand. This image shows part of the margin of the dune field. In this image the crescent nature of the individual dunes can be see in the upper left portion of the image. As the dunes coalesce the crescent form is lost.
