Poor Snowpack Structure
Avalanche Problem #1
Type: 
Wind Drifted Snow
Trend: 
Increasing Danger
Problem #1 Comments: 
Walking the ridge line up to the weather station, the NE shots down into Horse Creek seemed more loaded today than when I crossed above them on Friday. Winds continued to blow snow around today, and the forecast is for even more snow and strong winds tomorrow. I would expect increasing danger for wind slabs over the next two days.
Avalanche Problem #2
Type: 
Persistent Weak Layer
Trend: 
Same
Problem #2 Comments: 
On Friday I identified some faceted layers on a North facing slope. These did not react to stability testing. Today my party dug on a WNW aspect and found both facets and melt freeze crusts beneath the snowpack. We conducted two compression tests and got failures both times. We were about a third of the way up this slope when we dug the pit and decided to turn around. With more snow and wind in the forecast for the next two days these layers could become active.

Comments: 
Pit Details: Elevation 11,300, Aspect 288, Angle 28 degrees, Pit Depth 99 cm, HS 220 cm. We conducted two side by side compression tests in this pit. In the first CT we got the following results: CT16 PC @ 25cm down failing on 1 mm facets below a crust, CT 20 RP @ 37cm down failing on 1.5 mm facets, and CT24 BRK @ 41 cm down. The only result that really caught my attention on this first test was the result @ 37cm down since it was the only planar failure. We decided to do a second compression test for the sake of being consistent. While cutting the second column we got CTV RP @ 25cm down. This is a planar fracture that occurred upon isolating the column. We then got CT17 RP @ 37cm down. Pretty consistent results on the facets down 37cm, and a somewhat surprising CTV. Based on the results, we decided not to continue up the slope and to go ski somewhere else.
