With 13 km wide Piazzi Smyth as an almost flawless neighbor, Mt Piton looks like a stained tooth. Streaks of light and dark material visible on its flank suggest a new category of lunar feature: banded mountains. A closeup view provided by LRO/QuickMap shows the major dark and light streaks Leo captured plus additional thin ones. Like the steep rim of a crater wall these bands are due to light and dark material exposed near the crest of the peak that slip downslope. It may be that the dark bands are old material, darkened by space weathering, and the bright bands are more recently exposed material that will be darkened over time. One thing that we can be sure of is that splashes of impact melt didn't cause the dark streaks.
