I don't have enough information to make that call. From the narrow picture given it looks like rocks placed in the ground by an intelligent being. However I would need to see the surrounding area to see if they could be natrual weathered rock formations. However if we look at living things with the perspective we have of our earth, we see that they looked designed for a purpose.
Looking at them, they actually do rather look like rocks, don't they. Check the image name, though. They're termite mounds.

What's cool is that these mines are incredibly complex. Termite and ant colonies will make giant underground mazes, with individual rooms that are specifically ventilated to create proper airflow and sunlight availability. Different rooms will actually have different temperatures and humidity levels, because in some rooms they store food, in some they store eggs and pupae, and in some they actually
cultivate fungus. Gives new meaning to the term "ant farm".
Interestingly, they make these complex systems without design. The queen doesn't give the workers a blue print. It's just an instinct honed over millions of years.
