Zykov Glacier (-70.61667°N, 164.76667°W) is a valley glacier about 25 nmi long in the Anare Mountains of Victoria Land, Antarctica. It flows northwest and reaches the coast between Cape Williams and Cooper Bluffs. It was photographed by the Soviet Antarctic Expedition (SovAE) in 1958 and named for student navigator Ye. Zykov, who died in Antarctica, Feb. 3, 1957.

Geology

The underlying rock includes micaceous phyllite and micaceous schist; it was estimated by radioisotope dating (potassium–argon) in 1964 to be 410 or 420 million years old. A separate study of metamorphic rocks recovered from near the glacier (1959–62) found evidence of thermal crystallisation.

Location

The Zykov Glacier forms in the Anare Mountains to the north of Mount Hemphill and west of McMahon Glacier. It flows northeast past the Cooper Spur and Cooper Bluffs to the east, and the Buell Peninsula to the west, to enter the Pacific Ocean to the east of Cape Williams.
