The highway to the valley is slowly shrinking, amazing job keeping it open.

At 2280 meters the temperature was 0 as of 06:00, winds were 10-20 KPH from the SSE.
At 1550 meters the temperature was +2, 50 % relative humidity and the barometer is steady.
In the valley it is -1.

Avalanches from the past:
Lahaul Valley, India (1979, early March)
Five days of snowstorms creates deep drifts over the Himalayan foothills in the Indian state of Himachal Pradesh. A series of avalanches bury the valley beneath 15 to 20 feet of snow. About 200 people are estimated dead.

 Spearhead, coast range

I Did The Spearhead Traverse today from Blackcomb lifts with a singing pass trail exit.  Seems like today was the day for it.
  • Overnight recovery of the surface snow with –7 morning air temperatures.
  • Cloud increased through the day with some afternoon flurries.
  • Down hill skiing was fast on a supportive surface.
  • Uphill track-setting was challenging, even with ski crampons.  Hard on the feet.
  • Dust on crust high up on a few glaciers only.
  • Evidence of wet loose avalanches to size 2.5 on many solar aspects.  Several days old.
  • Some steep east aspects moist at mid day.  By mid afternoon refrozen as the weather changed.
  • Freezing level stayed below tree-line at approx. 1600 meters all day.
  • Tomorrow, Friday is the start of high freezing levels.  Right to ridge top.
  • The crust won't hang on as long.
  • Early starts are key, aspect is very important as the sun moves around through the day.
  • Singing pass trail was very fast and icy in the upper half.  Slow and wet through the bottom third.  The snow disappeared 1 km from the end.  Walking from there was pretty straightforward.

Still able to ski down from base 2 to the bottom of the wizard, with the forecasted temperatures it will be hard to keep the highway white.

Surprisingly, the crevasses are already sagging and opening up.  Someone fell in a hole near Decker yesterday!!
