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.
