2. “Hexagons”
For example, consider
the following hexagonal structure on the surface of Mars. While
hexagons do form naturally in crystals, it is difficult to imagine
such a large structure arising from natural crystal-forming
processes. The following photos were taken by Mars Global
Surveyor.

In this picture there
are actually two hexagons visible, the large one toward the center,
and a smaller one towards the lower left hand corner. Some unknown
geological process might account for the rise of such structures,
but if that were the case, how would one account for the apparent
isolation of the unknown geological process in this region, and for
the fact that only two such hexagons appear to have been
formed?
