With a distinctive wedge shape that resembles both a 'keyhole' and an 'exclamation mark', this feature raises the same question as most of the others do that are potential ancient monuments or buildings, rather than geological oddities: What will an artificial structure look like on Mars after possibly many thousands of years, or a million years, of erosion?
That this object displays clear symmetry is obvious, but if it is a building, is the surface area and its edges so weather-worn that it is bound to look like a geological feature after such a long time?
Whatever the case, when a unique, symmetrical shape exists in the middle of a largely empty area devoid of anything similar, it must provoke rational speculation.
Of course, rationally, we must accept the probability that it is just a random geological freak of nature. But also, we cannot ignore the possibility that this object might also signify that Mars was once host to an ancient civilization a very long time ago and that this is a remnant structure from that time. Not to consider this possibility, would in itself, be irrational.
POTENTIAL FOR AN ARTIFICIAL STRUCTURE
1. Unique isolated feature situated in landscape with no similar features for about 20 km in all directions 2. Displays a high degree of symmetry with very defined edges 3. Bears remarkable similarity to keyhole-shaped Japanese mound tombs ("Kofun") from 400-700 AD.
Geological feature that was either "lifted up by faulting, or that the surrounding terrain has been eroded down over billions of years, or indeed both" (Dr. Alfred McEwen, professor of planetary geology at the University of Arizona).
