AS15-M-1152 The feature formerly called Lambert Gamma, and provisionally renamed Mons Undest (a name not allowed by the IAU) is the shadow casting (and somewhat nose-shaped) hill below the "B" arrow. The large crater on the left is Lambert. The "A" and "B" arrows are pointing to parts of Dorsa Stille (on whose page the remaining nomenclature is explained).

  • There are two orbital Hasselblads of Mons Undest. They are: AS15-81-11027 and AS15-81-11029. An interesting Fairchild-mapping (metric) photograph, also made by Apollo 15, is AS15-M-1552 which shows Mons Undest near the lower left corner (can't miss it!).
  • Mons Undest was also captured on several of Apollo 17's orbital ITEK-panoramic frames, such as AS17-P-3071 (scroll to the right).
