serac
Quick Summary
A serac is a pinnacle, sharp ridge, or block of ice found among the crevasses of a glacier. These formations occur when glaciers move over areas with varying gradients, causing the ice surface to rise and fall. When crevasses intersect, they can create these jagged ice towers. Crevasses themselves are deep fissures or cracks in a glacier, formed by the stress of its movement. They can range in width and depth, and are often bridged by snow, making them dangerous and hidden hazards.123
