| There's a passage to the right, but it's under a huge serac that teeters at the end of a glacier, waiting for the next slight shift of ice to send it tumbling. |
| For many hours a way was won through a mighty turmoil of serac and over innumerable crevasses with varied fortune. |
| Whether a stone underfoot gave way, or whether the Admiral's voice brought down a serac of rotten wall, is not clear. |
| When a serac unexpectedly falls and instantly kills a climber, we are not fascinated, only touched by grief. |
| The region was one of serac where the glacier was puckered up, folded and crushed. |
| It is heavily crevassed, as though it once formed the serac portion of a glacier. |
