Snowpack Summary

Up to 30 cm of low density storm snow from the weekend is being redistributed into soft slabs in wind exposed terrain. The new snow is sitting on top of a mixture of surface hoar and weak surface facets which means the storm snow could become reactive when it settles into a slab. The mid pack is reported to be well settled. Reports suggest typical treeline snow depths are around 120-170 cm, but a report from the east side of region indicated a much lower snow depth of around 90 cm. Limited reports suggest the snow is well bonded to the crusts buried in mid and early November which are down 50-80 cm and 80-110 cm, respectively.
