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.

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.
