In a continued display of formations in the image ESP_016032_2600, this is the closest view of the 'leaf' or paisley shape which is repeated across dune crests which are seasonally defrosting during the imaging. 35-38 feet diameter. These well shaped relief structures are found in ordered centrered domination of many of the dark gully formations along dune crests. These also form in other circumpolar longitudes near this latitude range. In areas they dominate the low lying flat terrain where ice is high in percentage of the mix.
