Mass of glacial snow

Usage examples of serac.

Seracs reared like fortresses, aretes and nunataks traced in black the shape of buried mountains behind the green-white blister of the ice.

Between these lurid streams, underlying translucent colors and textures teasingly appeared: glassy seracs of ruby and rubellite, rounded moraines in blue tourmaline and amethyst.

The front edge was uneven, accommodating minor local differences in terrain, and a climb to the top would have revealed dips and ridges, seracs, and crevices quite extensive on a human scale, but in relation to its own size, the surface was uniformly level.

They came on ice-fields like mammoth ploughlands, where they scarcely made three miles in the day, and mountainous seracs which would have puzzled an Alpine climber.

The four of us stood there silent for a second, listening to the wind howl around the remaining seracs of the Godwin-Austen Glacier and through niches in the wind-carved boulders.

The South Ridge ran from right to left up early rocky outcrops before forming a long and elegant corniced snow ridge which led to a highly unstable area of seracs that mushroomed to the summit.

Simon must have fallen through the corniced ridge, yet the volume of sound suggested something more like a serac avalanche.

For the first half of its length the tongue of the glacier sloped fairly sharply from right to left down to the nunataks, crescent-fringed by the debris of moraines, that thrust up through the ice at the far corner of the dog-leg: the surface of the glacier was a nightmare of transverse and longitudinal fissures, some of them anything up to two hundred feet deep, great gaping chasms fanged with seracs - the irregular, often needle-pointed ice pinnacles that reached up between the walls of the larger crevasses.
