From the Ohm ray which crosses the easterly sector of Comrie as seen in the Clementine image above (middle), one immediately surmises that the crater must be older than Copernican (~ 1.1 bn years to present) in age. However, on closer examination of Comrie's overall appearance, one could go further to suggest that it may be older; as most of its northern, eastern and western sectors show a worn-looking appearance like one sees in a crater of the Eratosthenian (3.15 to 1.1 bn years old) or Imbrium (3.85 to 3.15 bn years old) period. Time has allowed for several dynamic events to take place; that of slumping, terracing, and smaller impacts around and within the crater, but most especially of note the total obliteration of any subsequent event-history that occurred in the crater's south-eastern sector by Comrie K (73 km in diameter). Comrie's floor is relatively flat except for a small hill or once-existant peak that may have been covered over by a clump of material from the Comrie K impact event to its south-east (note the ridge-highlight that starts at the peak's western sector and also the slightly shaded ridge to its east -- both connecting to Comrie's K's north-western sector). - JohnMoore2
