Definition

Noun: A large, permanent, and relatively flat area covered with snow and ice, typically found in mountainous regions or polar areas, that persists throughout the year.

Usage

A "snowfield" refers specifically to a vast, enduring sheet of snow, not a temporary seasonal covering. It is a geographical feature. * The climbers crossed a treacherous snowfield to reach the summit. * The helicopter survey mapped the shrinking snowfields in the Arctic.

Advanced Usage

• Scientific Context: In glaciology, a snowfield is often the accumulation area where snow compresses into firn and eventually glacial ice.
  • The research station was established to study the mass balance of the high-altitude snowfield.

Variants and Related Words

  • Glacier (n): A persistent body of dense ice that moves under its own weight, often originating from a snowfield.

Synonyms
