This is an area that is poorly represented in any of the Lunar Orbiter images that are readily available on-line. The IAU-named features visible in this rectified version of a photo taken with the medium resolution camera are: Kiess, Widmannstätten, Kreiken, Dale, Elmer and two lettered satellites of Kästner.

Dale lies just south of the Smythii Basin -- a 740 kilometre-wide basin of the pre-Nectarian period (~ 4.6 to 3.92 bn years). The rim of the crater looks relatively worn all around, however, while its northern sector shows signs of an old impact event on the outer, northern edge of the crater, the southern sector has a similarly-sized impact event where a crater about a third of the diamater of Dale itself has formed on top of the rim. The floor of Dale show little signs of change and, overall, the crater doesn't have any significancant detail of note. - JohnMoore2

  • This name appears on LTO-81C1. It does not appear to replace any previous IAU-approved designation. Although it appears in the cumulative list of approved names printed in IAU Transactions XVB, when and how it came to be approved is not entirely clear from the IAU record. - JimMosher
