Description
Elger
([/IAU%20Directions IAU Directions]) HANSTEEN.--A somewhat larger ring-plain, with a lower and more irregular rampart, rising on the E. to nearly 3,000 feet above the floor, which is depressed to about the same extent as that of [/Billy Billy]. Both the inner and outer slopes are terraced on the W., where the glacis is traversed by a short, delicate, rill-like valley. There are some bright curved ridges on the floor. On the E. of [/Billy Billy] and Hansteen is a wide inlet of the [/Oceanus%20Procellarum Oceanus Procellarum], bounded by the [/Letronne Letronne] region on the E., and on the S. by lofty highlands. On the surface, not far from the S.E. border of Hansteen, is a curious triangular-shaped mountain mass, with a digitated outline on the S., and including a small bright crater on its area. Between this and the ring- plain is a large but somewhat obscure depression, N. of which lies a rill-like object extending from the N. point of the triangular mountain to the E. wall. At the bottom of a gently sloping valley between [/Billy Billy] and Hansteen is a de
licate marking, which seems to represent a cleft connecting the two formations.

Nomenclature
- Christopher; Norwegian astronomer (1784-1873).
- A Reiner-gamma like surface formation (a swirl) north-northwest of Hansteen (at 7 degrees South, 54 degrees West) was probably called Burrell by Wilkins, and Melloni by Schmidt.

- Note: For all images, North is to bottom, East to left (taking into account the pre-1961 cardinal-point changes - see [/IAU%20directions IAU Directions]).
- Clearly [/Julius%20Schmidt Schmidt] and [/Hugh%20Percy%20Wilkins Wilkins] show the feature as a well-marked crater, however, when looked for in the [/Beer%20and%20M%C3%A4dler Mädler] maps of 1837 and the Neison maps of 1876 [/Neison%20-%20Map%2012 Map 12], the feature doesn't appear (Mädler shows it as two small ridge-like or hill-like features, while nothing at all appears on Neison's). Other, more recent mappers have also commented about the feature's appearance/disappearance, which further confused matters, for example, see this 1959 Irish Astronomical Journal article by Larson Milling. - JohnMoore2 JohnMoore2 ??
- Burrell was a contemporary English selenographer.
- Rimae Hansteen (an unofficial name for the system of rilles on the floor of Hansteen).
