hero snow
n.—Gloss: snow that is soft on top and firm underneath, providing excellent conditions for sport skiing.
«The firm base and soft granular top layer found in spring is also sometimes referred to as “hero snow.” It is so good for skiing that it bolsters confidence, hides technical mistakes and allows heroic recoveries from gross errors.» —“Realm of the Back Country Skier” by Michael Zeugin New Jersey’s Great Northwest Skylands (Columbia, New Jersey) Oct., 2007.
