About this image

This THEMIS visible image captures a complex process of deposition, burial and exhumation. The crater ejecta in the top of the image is in the form of flow lobes, indicating that the crater was formed in volatile-rich terrain. While a radial pattern can be seen in the ejecta, the pattern is sharper in the lower half of the ejecta. This is because the top half of the ejecta is still buried by a thin layer of sediment. It is most likely that at one time the entire area was covered. Wind, and perhaps water erosion have started to remove this layer, once again exposing the what was present underneath.
