The snowpack down in the Gooseberry zone of Fish Lake looked pretty similar to what we have on the Manti Skyline. There is a thick layer of loose sugary faceted snow at the base of the snowpack capped off with a number of layers of new snow above it. It is a very unstable situation. We dug a snowpit in one location and performed a stability test (Extended Column Test) where the weak layer collapsed and propagated as I was finishing cutting and isolating the column. (Video Below) In simple terms, a column of snow will not stand on it's own with the current snowpack structure. This problem is going to remain with us for the near future and perhaps the rest of the winter.
