  "id": "MLC-T-MET-004755",
  "term": "Crevasse hoar",
  "field": "Meteorology and atmospheric science",
  "definition": "Large, delicate ice crystals that form within the open spaces of a crevasse in a glacier. These crystals grow through the deposition of water vapor onto existing ice surfaces in a cold, moist, and relatively still air environment. Crevasse hoar can contribute to the instability of snowpacks when buried by subsequent snowfall.",
