The small Tharsis volcano called Biblis Patera is nearly lost amongst its gigantic neighbors. With a height of less than 10,000 feet, it is even dwarfed by many volcanoes on Earth. The gaping caldera of Biblis Patera shows evidence for multiple episodes of collapse, producing the concentric topography seen in the image. Several slope streaks are visible, indicators of a more recent and much smaller form of collapse: avalanches of the dust that thickly mantles the terrain.
