Got out and riding today the snow pack is starting to get deep enough to allow access into the back country so I did a ECT test on a 38° slope this is a north east aspect that seems to have experienced wind loading since my test pit was 6'3" deep and average snow pack was at 4'. There is about a 8-10" layer of loose facets at ground level. The rest of the snow pack is well bonded with no distinguishing layers. The slab failed at a count of 12 and came as one large colum all the way to the ground indicating very unstable conditions that will likely cause deep large avalanches, with large slabs. We also experienced womping on more gradual slopes with visible fractures. Mind your slopes the snow pack up Nebo is no different then else where in the state northly aspect have a weak faceted layer posing a serious threat of avalanches.
