Avalanche: Turnagain
Location: Magnum/Cornbiscuit
Started from Sunburst and went up to PMS bowl via NW ridge of Magnum. Then descended into Super Bowl to check on the snowpack in that area where a few large avalanches release on the basal facets in early November.
Avalanche Details
Saw evidence of small wind slabs along the SW face of Magnum along ridgeline beyond PMS bowl.
Weather
Cold temperatures down low today with calm to light winds. Some high clouds but mostly sunny
Snow surface
Surface hoar up to about 2000'. Then we got on a wind affected ridge and did not see it at upper elevations. Mixture of soft snow and wind stiffened snow at upper elevations.
Snowpack
We dug in two locations, one on a SW aspect of Magnum at 3400' and one on a N aspect of Cornbiscuit at 3000'. We found the layer of facets on the ground in both locations but they were moist enough to make a snowball. On the N aspect the facets were larger and more developed but did not show propagation in our extended column test.
Large facets on N aspect of super bowl
Snowpack structure at 3000' on N aspect of Cornbiscuit
Snowpack structure at 3400' on SW aspect of Magnum
Mixture of wind stiffened snow and soft loose snow on the surface in the alpine
Lots of wind effected snow on the ridgelines of 4940'
