Fans Field (MULTISPECTRUM; credits: Lunexit)

At the very beginning of Spring in the Southern Hemisphere on Mars the ground is covered with a seasonal layer of CO2 ice.
In this image there are 2 lanes of undisturbed ice bordered by 2 lanes peppered with Fans of dark dust.

When we zoom in to the image, we see that the Fans are seen to be pointed in the same direction, dust carried along by the prevailing wind. The Fans seem to emanate from spider-like features.

Image Data: the image is centered at -86,4° Latitude and 99,1° East Long.
The range to the target site was 276,1 Km (about 172,6 miles). At this distance the image scale is 55,2 cm/pixel (with 2x2 binning) so objects ~166 cm across are resolved.
The image was taken at 16:27 MLT (middle afternoon), with the Sun just 2° above the Local Horizon.
