Coloe Fossae – shaped by impacts, tectonics and ice
Here, the highlands drop away into the Utopia Planitia plain, which lies approximately two kilometres below (on the right of the image). The boundary is marked by tectonic extensional faults and is therefore heavily fissured – the result being a series of straight depressions cutting through the highland plateaus. Traces of glaciers can also be seen in the troughs, showing where ice transported rock debris along its flow paths.
