Birthday Bluffs
Birthday Bluffs are rock bluffs that rise to between Anniversary Bluff and Windscoop Bluff on the south side of Mason Spur, Hillary Coast, Ross Dependency. The feature comprises a series of cliffs that step up the escarpment. The name was suggested by geologist Anne C. Wright, Department of Geoscience, New [Mexico Institute of Mining and Technology], Socorro, who examined the bluffs on November 21, 1983, the birthday of her father, Peter Wright.
