High on Fisher Massif in the northern Prince Charles Mountains (East Antarctica) lies a thick sequence of uplifted glaciomarine sediment known as the Pagodroma Group. The rock rib starting lower left foreground is basement rock, and defines the sedimentary basin that was filled as the ancestral Lambert Glacier lay close to this area. This sequence is of Oligocene age (about 30 Ma). Note the tiny figure on top of the sequence to denote scale.
