From Switzerland French sérac (“kind of cheese; sharp tower of ice”), from Franco-Provençal sera, seré, from Latin seraceum, from serum (“whey”), from Proto-Indo-European *ser- (“to flow, run”). Sense 2 is from the resemblance of the towers of ice to the cheese, which tends to cleave into rectangular pieces.[1]

A serac (originally from Swiss French sérac, a type of ricotta-like whey cheese) is a block or column of ice formed by intersecting crevasses on a glacier. Often house-sized or larger, they are dangerous to mountaineers since they may topple with little warning. Even when stabilized by persistent cold weather, they can be an impediment to glacier travel.
