Layers of "B"
image by Wyckliffe Hoffler, Titusville, FL
Old favorites are always a pleasure, especially when imaged by a first time contributor to LPOD. This low Sun view of the bumps and hollows on the floor of Ptolemaeus joins a series of Birt its rim would have been about 800 m above the surroundings. So "B" didn't form on the original floor of Ptolemaeus - which would have been about 5 km deep - so it impacted into a much higher level of crater fill. But what would that be? Did "B" form in between the next to last and last ejecta layer from Imbrium? Or was Ptolemeaus nearly filled with lavas, like Plato, before "B" excavated a crater, and was then draped by debris from Imbrium?
