To compound the difficulties it appears that the North side of the
hole has a certain rayed effect from an impactor. It's almost as
if an object struck the top of an evacuated lava chamber and caved
in.
If you look at the full resolution image, you can see that the area
north of the hole appears to be sand dunes. I don't see anything to
suggest an impact (other than the shape of the hole), but it's
interesting to consider what's different on the north side to produce
these small dunes. It's as if the entire area is slightly raised or
depressed, affecting the prevailing winds. I don't know how fine the
topographic data for this area is. Maybe a big hole on flat terrain can
also affect the local air flow?
