Lots of things here. In the lower right is a huge crater shaped like an open bible. Very symmetrical, with distinct "ribs" or "pipes" along the right edge of the crater.  They do look like they have been constructed.

But I really am puzzled by the tall white obelisk in the center, about two inches from the top. Pointed and white, with a long thin shadow stretching to the right.  I have emphasized it below.
