About this image

This image is located along the margin between Terra Cimmeria and Elysium Planitia. This boundary region is typified by tectonic fractures forming long, linear depressions. The crater in the lower half of the image has a hexagon shape rather than the normal circular outline. The regional surface/subsurface fracture system deflected the impact generated pressure waves along the tectonic network, causing the linear sides we see in the image. Meteor Crater in northern Arizona has a similar flat sided shape, in that case a square rather than a hexagon. The Arizona crater impacted into sandstone and limestone that had a right angle fracture system.
