Tantalus Catena

This VIS image shows part of Tantalus Catena, just one of many north/south trending tectonic graben located south and east of Alba Mons. While other graben in the area are identified as fossae (defined as a long, narrow depression), the circular depressions within this graben lead to the descriptor name catena (defined as a chain of craters). In this case the craters are a result of roof collapse into an underlying open space such as a lava tube.
