This labyrinth-like system of troughs and plateaus was imaged by ESA’s Mars Express on 21 June 2016.
It shows part of a region known as Adamas Labyrinthus, which is found in Utopia Planitia in the northern lowlands of Mars. Here, the randomly shaped blocks vary in size from 5–20 km across and are separated by cross-cutting troughs with widths of up to 2 km.
The pattern is similar to that observed in some offshore locations on Earth, supporting an idea that the scene here results from the deposition of fine-grained sediments in an ocean.
