Irregular Mare Patches (IMPs) from LRO in Lamont. Quickmap view http://bit.ly/2w3oTzu Lat 4.52N, Long 22.83E

IMPs are pothole like features most likely due to collapse of a patch of foamy lava. They look recent, but are most likely very ancient because the surface doesn't retain impact craters well.
