Crevasses are a feature of ice sheets but how deep they extend has been a mystery. Now crevasse traces have been visually identified to 265 meters in a borehole in a fast-moving outlet glacier.

Satellite Captures Detaching Iceberg in Near-Real Time
NASA’s ICESat-2 satellite recorded the cleaving of a 315-billion-ton iceberg from Amery Ice Shelf in 2019, as well as years of subtle cracking and splitting prior to the calving event.
