Description
Cockcroft is a crater of the pre-Nectarian period (~ 4.6 to 3.92 bn years). The appearance of its well-worn rim, along with several major impacts both around its exterior and within its floor show that the crater has a history of alteration beyond initial formation. Impacts, for example, to its south-western sector show how Cockcroft N has obliterated nearly all of its southern sector, while others to the east and south-east has produced a complex history of bombardment beyond recognition. Some worn terraces can be seen in portions around the crater's interior rim, however, prominant to these would be the main crater-impact in the south-western sector of the floor (nearly half the diameter of Cockcroft), which itself has subsequently seen several smaller impacts of assorted sizes. No sign of a central peak exist within Cockcroft for such a sized-crater (93 km in diameter), however, given the above history of alteration and events, the equation for one existing initially at all must surely be one to be pondered over. - JohnMoore2
