Grand Central Station

Palus Epidemiarum is a patch of mare occupying the southern armpit of Humorum and Nubium. This is a highly concentrated area of rilles that have little obvious relation to nearby basins. K.C.’s magnificent image shows how most of these rilles intersect near Ramsden - which I liken to the old Grand Central Railway Station in New York City where all the train tracks for the eastern seaboard came together. The Clementine altimetry map demonstrates that Palus Epidemiarum slopes downward in elevation nearly 2 km from the SW to the NE. But the rilles don’t appear to be related to this slope. Two of the rilles deserve attention. South of Ramsden there is a delicate feature that appears to be a crater chain (cc in mouseover). But this does not appear to be a secondary crater chain for there is no obvious parent crater. A strange wide rille or more likely a pair of rilles (pr) crosses a small patch of mare just W of Mercator. Finally, notice the high NE rim of Marth. I believe that concentric craters like Marth are impact craters that have somehow been modified to create the inner rim. But the high NE rim is difficult to explain as an impact feature - what is it?
