- <p>Snow below 8,300' was very close to isothermal ( 32°F or 0°C) on all aspects. There was a very slight melt-freeze crust 12" below the surface on northwest facing slopes, but this was spotty and not in all locations. This crust was very damp to wet and shouldn't pose a problem. The surface refreeze was about 6" deep at 9,500' and very supportable this AM. Below 8,300' the snow surface was less supportable on north facing slopes and slightly more supportable on southerly aspects. The trend on this warm and wet snow problem will vary with temperatures and wind speeds. </p> <p>Signs of wind-drifted snow along the ridgetops with cornices (small- about the size of 2 drawer filing cabinets) that were sensitive on southerly facing ridges at 10,800'. We could see areas where the wind had loaded and scoured slopes, but did not see any wind slab problems. </p>
Up to 1/2" of new very high density snow fell above 8,100'. Snow surface was mainly melt-freeze crust above 8,300' and damp snow below that level. There was some breakable wind-crust at the highest elevations (11,000' +) and the snow on the high elevation north and east facing terrain was still dry. The snowline was roughly 6,800'.
