The traverse into the back country on Spearhead flank was very busy yesterday morning!

At 2280 meters the temperature was +1 as of 06:00, winds were 30-50 KPH from the SE by S.
At 1550 meters the temperature was +4, 88% relative humidity and the barometer is dropping.
In the valley it is +4. A trace of wet snow was observed at 1550 meters.

The snow pack will certainly begin to transform with the temperatures and expected precipitation.
