Mons Gruithuisen Delta
Mons Gruithuisen Delta
Lat: 36.0°N, Long: 39.5°W, Diam: 20 km, Height: km, Rükl: 9
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.

Lunar Orbiter 5's Frame 183 shows both Gruithuisen Gamma and Delta, and also the chain of teardrop-shaped craterlets near the concentric crater Gruithuisen K (near the photograph's upper left corner).- DannyCaes Mar 23, 2008
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.
- Age estimate of 3.85 to 3.7 billion years based on crater counts (Wagner et al, 2002, Stratigraphic sequence and ages of volcanic units in the Gruithuisen region of the Moon. J. Geophys. Res. 107, E11, 5104 ).

- 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.
