Natural or Artificial?

The "D & M Pryamid" on Mars

I have looked at many of the pictures that people are claiming might be artificial structures on Mars, but most are not really all that convincing. You have to want to see something there to believe it- like "The Face" which is located not far from the "D & M Pryamid" above. This "Pryamid" structure is the most anomalous to me. I find it very hard to imagine any natural processes that might have formed such a structure. I have not ruled out natural processes, but this structure certainly makes me take the artificial hypothesis seriously.
