Description
A crater of the pre-Nectarian period (~ 4.6 to 3.92 bn years), Comstock shows all the signs of a well-worn, well-bombarded, well-aged crater that has seen more than its fair share of impact history. Not a portion of its once existant rim (let alone its floor) can be seen amongst the turmoil of impact events which have altered respective regions through further impacts, slumping, and ejecta deposits from prominant basin events like Hertzsprung to its south and Orientale to its south-east. Ohm crater (Copernican ~ 1.1 bn years to present in age) to its south-east has also overlain traces of ray material onto its hard-defined floor -- better seen in this Clementine image from Map-A-Planet. - JohnMoore2 JohnMoore2
