The Square Mesa and related formations are hypothesized to have been islands in a paleosea that lasted over 1 Ga. Similar life compatible geology may exist to that found by the curiosity Rover in nearby Gale Crater. The biotoxicity of Martian soil should have allowed for life to evolve in this area, lithopanspermia may have allowed for microorganisms such as lichen to be transported from Earth to Mars into this paleosea. The wall like shapes on these formations occur only on some islands but not on others close by in the same geological conditions and processes involved in their creation. The Square Mesa shows signs of bricks of the same size repeating, also layers of constant thickness.
