About this work
This VIS image shows part of Tractus Catena, just one of many north/south trending tectonic graben located south and east of Alba Mons. The graben with circular pits are part of Tractus Catena. The graben without pits are part of Tractus Fossae. The pits most likely formed as a result of roof collapse into an underlying open space such as a lava tube. Graben are formed by extension of the crust and faulting.
