Mons Gruithuisen Gamma

Mons Gruithuisen Gamma (γ) is a lunar dome[1] that lies to the north of the crater Gruithuisen at the western edge of the Mare Imbrium. It is located at selenographic coordinates 36.6° N, 40.5° W.

This massif is shaped as a rounded dome in the surface, occupying a diameter of 20 km and climbing gently to a height of 900 meters.[2] At the crest is a small crater. This formation appears foreshortened when viewed from the Earth, and it has been described by Antonin Rukl as resembling an "upturned bathtub".[3]

To the east lies the similar Mons Gruithuisen Delta (δ). Together they are often informally called the Gruithuisen domes.
