Earth:Fosdick Mountains
The Fosdick Mountains ( [ ⚑ ] : 76°32′S 144°45′W / 76.533°S 144.75°W) are an east–west trending mountain range with marked serrate outlines, standing along the south side of Balchen Glacier at the head of Block Bay, in the Ford Ranges of Marie Byrd Land, Antarctica. They were discovered by the Byrd Antarctic Expedition in 1929, and named by Richard E. Byrd for Raymond B. Fosdick, who became president of the Rockefeller Foundation.[1]

Geology and geography
The dominant topography is tall, steep-sided ridges, trending north-south, with peak elevations spanning 1000 to 1200 m.[2] The range consists of the Fosdick Metamorphic Rocks[2] of migmatite gneiss and granite. Metamorphism occurred in the middle of the Cretaceous period.[3] Mount Perkins is a Pleistocene volcano within the range.[4][5]
