Route & General Observations

1030-Our group of three ascended the standard skin track towards treeline to assess moving into alpine. We performed snowpack tests at 2,700ft. and skied two laps from Common Bowl to the northern tree meadows. The fresh snow above 2,000ft is dry, light and fluffy with moist, still fluffy snow within treeline.
The once wind-scoured ridgelines may be deceiving with fluffy new snow on top only to surprise the best with core shots or rocky pole plants.
