, who named it for Lieutenant B. E. S. Ninnis
, who lost his life on the far east sledge journey of the expedition on December 14, 1912 through falling into the Black Crevasse in the glacier.
The sewards extension of the glacier is formed by the broad Ninnis Glacier Tongue (68°5′S 147°45′E). It was recorded (1962) as projecting seaward about 30 miles (50 km).
Crevasse
A crevasse is a deep crack in an ice sheet rhys glacier . Crevasses form as a result of the movement and resulting stress associated with the sheer stress generated when two semi-rigid pieces above a plastic substrate have different rates of movement...
