Mostly clear skies prevailed today with generally cool temperatures. Winds were more substantial this morning as we made our way up from tamarack. Some flagging was obvious along the crest and some snow was moving around below treeline. The winds dropped dramatically by mid-morning however and remained mostly light for the remainder of our day.
We dug in near the top of Tj Bowl in an area with 180 cm total height of snow and found a similar structure as we have been finding throughout the range. About 120 cm of snow from our big storm last week that is relatively right side up and seems to be consolidating nicely resting on top of a weak faceted base. Stability tests continue to show this weak layer to be reactive, however, triggering the failure seems to be getting harder over time. see the image below for more information.
Surface conditions are variable with the most pleasant conditions being in sheltered treed areas. As soon as we entered more sparsely treed areas near treeline we noticed surface conditions were much more wind affected. We did not observe any areas with supportable windboard or recent wind deposits but we did find the descent to be a bit grabby.
No obvious signs of instability were noted on our tour today apart from our propagating test results. however, as we look forward to next week’s storm cycle it’s worth noting that we observed some decent surface faceting in shaded and protected areas and some thin melt-freeze crusts in areas with full sun.
