Firn snow

Névé /neɪˈveɪ/ is a young, granular type of snow which has been partially melted, refrozen and compacted, yet precedes the form of ice. This type of snow is associated with glacier formation through the process of nivation. Névé that survives a full season of ablation turns into firn, which is both older and slightly denser. Firn eventually becomes glacial ice – the long-lived, compacted ice th… WebFirn snow. Firn snow is a type of snow that is at least one year old and has therefore gone through at least one summer. Firn therefore only occurs in high mountainous areas. It is snow that has lasted for several years and has not yet metamorphosed into glacier ice. Firm forms when fresh snow falls repeatedly onto an existing layer of snow and ...
