Description
Aged as Late Imbrium (~ 3.85 to 3.8 bn years), Bjerknes more than likely formed on ejecta deposits from the Australe Basin - a 880 kilometre-wide basin of the pre-Nectarian period (~ 4.6 to 3.92 bn years) whose outer rim lies just ~ 150 kilimetres away to its south-west. The crater has a somewhat sharp-ish rim for its age, but on closer examination signatures of inner wall-collapse, terracing and an infilled centre suggest Bjerknes has been through the time-mill. Only one or two small craters dot its centre and south-western rim. - JohnMoore2
