No Longer Unremarkable

Along the northern edge of Mare Vaporum is a small hill that has managed to remain unremarked upon. But now Raf and
Barry have shown that it is remarkable. The inset LRO image at middle left shows the hill is a smooth bump adjacent to a
ruined crater. Unremarkable. But the two bottom images totally change the story. The hill is very dark and a broad swath
of the darkness extends over the rim of the ruined crater. Raf and Barry make the reasonable argument that this is a pyro-
clastic coating of the hill. The LRO Path tool shows that the hill has a smooth profile, and rises 620 m with an average
slope of 13°, considerably steeper than the normal mare swell/dome near the right side of Vaporum. Raf and Barry propose
that this hill is a volcanic cone, constructed by lava flows, and then followed by an explosive eruption of ash. This cone is
similar to the steep hills of the Marius Hills. Why is it here all by itself?
