This HiRISE image shows some unusual blocks within two adjoining craters near the highland-lowland boundary of Mars. The blocks could be associated with the collapse of the crater floor and their unusual shapes suggest that they have been subject to significant erosion.

Surrounding the blocks are relatively light-toned trains of aeolian bedforms, covering a range of different sizes. The light colour of the bedforms indicates that they are covered in dust and probably not moving today.
