Mars - Viking 2 Orbiter

Biblis Patera volcano, Mars

The small Martian volcano Biblis Patera is shown in this Viking 2 Orbiter image. The diameter of the exposed portion is about 100 km. Truncation of the flow features on the volcano's flanks by surrounding plains material indicates that part of the edifice is buried. Note the circular faults surrounding the caldera. North is at ~11:30 in this image, which is about 200 km across. (Viking Orbiter 044B50)
