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?
The question may come down to, "Where on Arsia Mons is the
hole located?" I didn't think the Shield Volcanos were noted
for their sand dunes but then again Mars is a sandy place.
If the hole is on the South slope then the tops of the dunes would
perhaps slide off into the pit causing fresh material to be exposed.
Would this material be brighter than the surrounding dunes?
I think it's likely.
