Example Lava Natural Arch

NABSQNO Mars-188.13-24.50. This feature was discovered on image PSP_001420_2045 taken with the High Resolution Imaging Science Experiment (HiRISE) onboard the Mars Reconnaissance Orbiter (MRO). A more complete description of the image is found here. It is likely that this feature is a lava natural arch. If so, the span of the arch is at most 30 meters, the height is at most 15 meters, the width is 25 meters, and the thickness is probably about 5 meters.

A discussion of how natural arches probably form on Mars and the clues they can provide toward an understanding of the recent history of the Martian surface is found here.
