Comments
Not placing a problem on the board at this time- for this zone. Which is one of the deepest in the Wasatch. However, the persistent weak layer that was buried around Nov 18th still presented itself in every profile we performed (12 across a football field sized piece of terrain at 9400' on North facing terrain). The height of snow in this area varied from 90-140cm. We performed over two dozen snow pack tests across the student group. Most notable results were a couple of ECTN down 25-30cm on the previous interface between the early December storms. A handful of our PST tests targeting the weak layer showed propagation at around 50% of the cut length. And while we did get one or two CT SC in that same layer, it was on the hardest set of taps. All this nerdery indicates we have a verifiable low danger. No class one data (recent activity) was observed. However, I will always maintain my ability to be surprised by an outlier and we didn't push into consequential terrain. Enjoy the facet harvest while it lasts.
Pictures:
PST in one profile. 50/100 End. North facing 9400'
East facing terrain at 9400'. Note the textures and ability to still make out the ground configuration of this boulder field. This was the shallowest area at about 50cm deep.
Sinners Southeast facing slope at 9800. See the subtle sheen?
