|Location:||Cornbiscuit -> Magnum PMS Bowl|
Route & General Observations
- Cornbiscuit lot to 2000′ on Cornbiscuit’s NW aspect, then down and up Magnum/PMS Bowl on a SW to W aspect to 3100.’
See pit results below. No collapsing or cracking, even to 2000' where a pre-existing skin track didn't exist. No recent avalanche activity observed.
Overcast, with the ceiling lowering and occasional light snow increasing to 1cm/hr by sundown. Temps in the 20s. NW winds light gusting moderate above treeline, with the direction likely caused by terrain channeling.
At 1300' - 40cm of fist hard snow (from last week & buried facets) over a stout 10cm melt freeze crust. This sat over 20cm of moist snow. Height of Snow = 70cm
At 1500' - 55cm of fist hard -> 4 finger hard snow (from last week & buried facets) over a stout melt freeze crust.
At 2000' - same surface conditions as 1500' observation.
Above 2000' - generally 30-50cm of soft snow over a crust or harder layer. Wind slabs up to 20cm thick were occasionally present on West and SW aspects; no cracking or collapsing. South aspects generally softer. Ski Penetration (PS) ~ 10-25cm from 2000' to 3100' in PMS bowl.
Overall, less recent snow, shallower ski penetration, and more recent wind affect than observed on Eddies yesterday at similar elevations.
Snowpit Results: Elevation=3100', 18 degree slope, SW aspect, HS=120.
Pit was dug to the ground in PMS Bowl, several hundred yards off the ridge.
Surface to 30cm: Fist hard -> 4 finger hard snow from last week
@30cm: 2-4mm buried surface hoar (see photo of layer below)
30-40cm: 4 finger+ rounding facets
5cm softer layer (4-finger) hardness density change
70cm well bonded pencil/1finger layers
5cm of 4 finger basel facets on the ground.
CT21 Resistant Planar & ECTN21 Resistant Planar 30cm from the surface, with the buried surface hoar failing.
