Awesome Pitatus

Pitatus is one of the under-appreciated gems of the Moon. With a diameter of 97 km it is about the same width as [../01/LPOD-2004-01-24.htm Plato] (101 km), but has a much more interesting interior. Presumably Pitatus was a Copernicus style crater when formed, with magnificent concentric wall terraces and a large central peak. Today the crater's rim is heavily battered by later impacts, the terraces are mush, the central peak is still there, and the floor is filled with mare lavas. What this extraordinary image shows is that Pitatus has an amazing system of rilles that hug the edges of the floor, with some fainter ones crossing it. In two places - the upper left (west) and the middle right (east) - the rille looks like the mare material it formed on was domed up, like a crack on the crust of home baked bread. Pitatus is another example of a floor-fractured crater - like [../01/LPOD-2004-01-15.htm Gassendi] and [../01/LPOD-2004-01-09.htm Posidonius] but its rilles are more concentrated around the floor edges. FFCs are thought to result from a magma intrusion that lifted the entire floor (hence the high - 480 m - central peak) and perhaps domed it, producing the tension craters around the edges.
