Geomorphic Gumbo

Just northeast of the small Tharsis volcano Biblis Patera lies a scene of surprising complexity. The upper left portion of the image shows the furrowed terrain of Gigas Sulci, likely produced in response to the evolution of Olympus Mons volcano. A narrow channel that probably contained flowing lava snakes through the center of the image before transitioning into a gaping chasm. The lower third of the image shows a jumble of textures, presumably produced from the emplacement and erosion of lava flows, but which are not easily classified.
