Barkla
Gazetteer of Planetary Nomenclature, International Astronomical Union (IAU) Working Group for Planetary System Nomenclature (WGPSN) Due east of Barkla is Kapteyn, a formation only slightly larger with a similar size. Southwest of Barkla is the crater Lamé.
The rim of Barkla is very nearly circular, although it is slightly elongated to the northeast and southwest. The wall shows little appearance of erosion from subsequent impacts, and is not overlain by any craterlets of note. At the midpoint of the floor is a central peak, which joins a low ridge running to the south and northeast.
