Avalanche Problem 1: Normal Caution
  • Type ?

Remain vigilant for isolated pockets of instability throughout the range.  Consider the possibility of small loose wet activity if small pockets of windblown snow and residing old snow on S-W solar aspects are loosened by heat and solar input.  Scabs of old wind slab that have been dis-connected from residing snowfields by eroding winds are also features to be on the lookout for.  Surface conditions are extremely variable with a plethora of obstacles and your exposure to them remaining the biggest hazards.
