Non-Avalanche Related Snow Immersion Death; victims suffocate and/or asphyxiate themselves after falling either into a conifer tree well or into a deep snowbank.

this definition is a little sketchy as you can also use the term NARSI for any incident involving tree wells or deep snowbank immersion without death
