Left: Howard Eskildsen The 16-km diameter crater at the top of this north-up Earth-based image is Mairan A. Following the ridge south from this one encounters two prominent blister-like peaks. The one on the left (in brighter sunlight) is Mons Gruithuisen Gamma. Mons Gruithuisen Delta is to its right, and to the right of that, the 9-km crater Gruithuisen B. The more scab-like hill to the south of these, once known as Gruithuisen Zeta, is no longer named.
Right: SMART-1 This space-based view, with north roughly to the left, appears to have been taken from over Gruithuisen Zeta (the scab-like hill). Mons Gruithuisen Gamma is partially visible in the lower left corner with Mons Gruithuisen Delta and Gruithuisen B above it. The northern rim of 15-km diameter Gruithuisen is visible near the top of the right margin.

Description
Diviner IR data identifies this as one of the most silica-rich volcanic regions of the Moon. (Glotch et al, , 2010).

(IAU Directions) GRUITHUISEN DELTA AND GAMMA.--On the N. of this bright crater, in N. lat. 36 deg., W. long. 40 deg., rises a fine mountain, delta, nearly 6,000 feet in height, and on the N.W. of it the larger mass gamma, almost as lofty.

Nomenclature
- Named from nearby crater. (Gruithuisen)
- In the original IAU Nomenclature of Named Lunar Formations this feature was known as Gruithuisen Delta. Although all such Greek-lettered names were discontinued in IAU Transactions XVB (1973), this name was restored (with the addition of the Latinized "Mons" prefix) in IAU Transactions XVIB (1976).
- In his informal 1953 tour of Mare Imbrium, Leland Copeland referred to the Gruithuisen domes as the Three Rocks. D.Caes research.
