Description
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
