A Small Sea of Lava
image by Harald Paleske, Langendorf, Germany
Originally published June 10, 2011.
Looking acroos the 200 km expanse of Schickard's floor reveals dramatic shadows and an interrupted surface. Most of the floor is lava that flowed over the original deeper floor, hiding a central peak and wall terraces. Are the few small hills remnants of otherwise buried crater rims, or perhaps hints of a inner ring? Their lack of circularity suggests that the mare ridges aren't draped over covered craters, so I wonder what forces caused their formation? The larger parallel ridges at upper left are layers of ejecta from the formation of Mare Orientale. The lavas actually flow around these ejecta ridges, showing that the lavas erupted after the formation on the basin. And as everywhere, random impacts cut the surface with mostly small craters.
