Looking at a photo from the Opportunity Mars Rover and i see something i can't explain and wanted to see what everyone else thought.
to me it looks like a Mound of somekind and looks out of place imo. could something be living inside that ? it does appear to have a round opening at
the top of it.

this mound is on the left side of this area in this picture below and looks to me that if there was any life here this would be a perfect spot for
it.
