re: Holy Mars!
i agree with you. These holes are very interesting!
They appear to be very good circles, and many of them
come in matched pairs.
Even when the holes of a matched pair are larger,
the distance between their centers expands in what
looks like the same ratio as the smaller pairs.
Also did you notice the pair in the upper rock facing
Spirit. Each has two bars inside at the same angle
relative to each other.
Any geologist here wish to hazard a guess as to how
these were formed?
