- According to NUNKI, a frequent visitor of the LPOD site, the crater Bridgman was captured on Apollo 13's Hasselblads AS13-60-8657 and AS13-60-8666. In the first frame, Bridgman should be the crater at bottom center. In the second frame, Bridgman should be the crater at center. - DannyCaes Feb 6, 2011

Description
Bridgman is a crater of the Nectarian period (~ 3.92 to 3.85 bn years). As it lies some 600 kilometres north-west of the Moscoviense Basin -- a 420 kilometre-wide basin of the same period, some ejecta deposits may lie mixed within the crater, or, perhaps, on it. The outer rim of Bridgman looks relatively sharp for its age, but several landlides have occurred all around forming the obvious-looking terraces. The southern section of these terraces seems to have expierenced some further division in their formation as the eastern section is much more broader in its extent than that of the west side. Would this be due to the already-above-mentioned Moscoviense Basin event, or the Humboltianum Basin just north-west of Bridgman that also occurred at the same time? The floor of Bridgman looks relatively flat, and a small series of peaks in its centre make up what was once a prominant peak.- JohnMoore2
