Observation

Description of Snow, Weather, and Avalanche Conditions:

Started the tour with thick cloud cover. As we began ascending towards the north bowl the heavy clouds became mist/ 100% humidity. We broke out of the treeline and the mist immediately turned into full rain all the way up to 8400'.

Any unconsolidated snow had turned to mashed potatoes and the upper 2" of snow were saturated.
