Description
Bergstrand has impacted close to Aitken crater in the north-west -- a crater of the Late (upper) Imbrium period (~ 3.85 to 3.8 bn years), which has itself formed on deposits of the huge South Pole Aitken Basin -- a 2500 kilometre-wide basin of the pre-Nectarian period (~ 4.6 to 3.92 bn years) predominatly in the south-east. Bergstrand's rim is slighly oval-shaped in a north-south direction -- both cardinal extremes of which show signs of collapsed material in towards its pock-marked floor covered in hundreds of small craters. Is this collapsed inner-rim material a sign of the age of Bergstrand, or is it due to the material make-up on which it formed (note how craters on this inner-rim material has less number of small craters than those showing on the floor)? - JohnMoore2
