Glacier crevasse
From Openwaterpedia
Josef Köberl will attempt an Ice Mile at 3,216 meters (10,551 feet) within the glacier crevasse at the Nature Ice Palace on the Hintertux Glacier in Austria in water temperatures between -0.3°C and -1°C
noun - A glacier crevasse is a deep crack, crevice or fissure found in an ice sheet or glacier, or earth. Crevasses form as a result of the movement and resulting stress associated with the shear stress generated when two semi-rigid pieces above a plastic substrate have different rates of movement. The resulting intensity of the shear stress causes a breakage along the faces.
