Summer and early Fall Travel Advice
Avalanches and avalanche accidents can occur in snow-covered mountains year-round.
Travel safe and have fun!
-
In terrain where snow remains year-round, choose terrain and travel practices that minimize your exposure to avalanches.
-
If you see recent avalanches, you may be able to trigger others.
-
Winter-like weather means winter-like avalanches. Expect an increased avalanche danger during or just after storms.
