There are three active dust devils in this image, but they aren't monsters like this picture.

Especially interesting is the stereo anaglyph with ESP_026051_2160, acquired just two weeks after this one.

Viewed with red-green glasses, the active dust devils seem to float above the surface. There are also some bright lines present in only the later image--those are the tracks of dust devils that passed through this region in the prior two weeks.

This is a stereo pair with ESP_026051_2160.
