Description
With its worn-down rim (nearly non-existant on its western side), its smoothed-down terraces (on its eastern side), and a central region bearing a series of degraded peaks that take up about a quarter of its floor, Berkner has all the appearance of an old crater. Several small craters ranging from 5 to 15 kilometres lie on portions around the rim as well as on the floor -- the latter of which shows a more hummocky appearance in the sourthern region than in the north. Two craters in which to compare Berkner's appearance would be [/Robertson Robertson] just to its south, and [/Parenago Parenago] just to its west -- Robertson is of [/Stratigraphy Copernican] age (~ 1.1 bn years to present) and looks relatively fresh, while Parenago looks much, much older (age period -- required ???). The [/Lorentz Lorentz Basin] lies some 400 kilometres in a north-easterly direction away from Berkner while the [/Mare%20Orientale Orientale Basin] lies about 1300 kilometres to its south-east -- both of which may have contributed ejecta deposits and secondary bombardment upon the crater. - JohnMoore2 JohnMoore2
