The Tantalus Fossae are a large network of grabens surrounding the Alba Patera volcano. They extend over 1000 kilometres in a north-south direction and are between two and 10 kilometres wide and up to 350 metres deep. They were formed by local and regional tensions in the Martian crust, which were created, among other things, by the uplift of the Alba Patera volcano. The crater in the image is intersected by several grabens. This indicates that it was formed before the end of tectonic activity. North is on the right of the image.
