Catena Littrow
| Lat: 22.2°N, Long: 29.5°E, Length: 10 km, Depth: km, Rükl: 25 |
AS17M-0446 The large crater at the bottom of the field is Clerke (formerly Littrow B), and the rilles are part of Rimae Littrow. The identity of Catena Littrow is slightly confused, but it is presumably the chain of craters extending east from (and probably including) the feature labeled Littrow BA (see Nomenclature).

Nomenclature
- Named from nearby crater. (Littrow)
- The name Catena Littrow was introduced as a replacement for Littrow BA on LTO-42C2. The placement of the name on the LTO makes it ambiguous what it refers to. The name Littrow BA does not seem to appear on the System of Lunar Craters charts, put it is indicated on LAC-42, where a dot suggests it was meant to apply only to the crater indicated by the white arrow in the Apollo 17 view shown above. Evidently the IAU interprets the catena name as applying to the chain of craters extending to the west over a distance of about 10 km (rim-to-rim). Note that near the middle this scar of craters is crossed by a much thinner chain running north-south over a total distance of about 6 km. Whether this is part of the IAU-named feature or not is unclear. - JimMosher
