I was looking at a NAC image from a section of Mount Hansteen that was downloaded some time ago, but I had not examined in any detail (and have yet to look more carefully at it still), but this interesting black crater (if that is what it is?) caught my eye. Anyone have an explaination as to why it could have excavated such black material from otherwise bright mantle deposits? The only explainations I can think of is there are some pyroclastics beneath the surface, or the impactor itself was composed of dark material. But really at a loss to explain it.
