Reptilian Secret Underground Base has been melted and drain like mudslide?

It looks like just a mudslide, but the surface earth color is red. Then why the mud is like cement?

This hill itself looks really suspicious artificial hill. This hill might cover up Reptilian Secret Underground Base. It is highly possible that Galactic Federation of Light melted Reptilian Underground Base by their Direct Energy Weapon. Then inside melted construction material started oozing out.
