Skied up the highway side of Observation Sub-Peak today with fellow ski guide
Ken Bibby and a group of university students.
Broken clouds and convective snow flurries kept the temperature around -2.
There was a moderate northwest wind transporting snow across the summit ridge.
We skied down via the south facing bowl off the summit, into the drainage known
locally as Jimmy Simpson Creek.
Ken skied over to assess the open south east facing slope below the summit, at
about 2850m. He found 40 cm of soft slab on a buried sun crust. As he was
skiing back towards the group and reporting that the stability was suspect, a
20 - 60 cm deep fracture released 15 metres behind him. It was 75 m wide and
ran 250+ m on the buried sun crust.
We were able to safely descend the south facing slope adjacent to the avalanche
on a stiff surface of sun crust (so no slab avalanche danger).
