Alien Anomalies

If anyone wants to spend a happy weekend looking at old MER Opportunity photos, this one 

and this one

will possibly convince you of tiny aliens, or maybe not.
In the first one I see civilisation evidence and in the second there are triangular pipe-like structures sticking up among the stones.

If you see nothing out of the ordinary for a dry desolate 'uninhabited' planet, then either I am barking mad or you are in denial.

All those who see something small and perfectly organised in these pictures, all together now...bark.
Woof! Woof!
