Snowpack Summary

Above 1000m about 60 cm of new snow has fallen with as much as 80-90 cm of new snow at higher elevations. This storm snow now covers a crust that was buried on January 17th. Below this crust the upper snowpack which consists of 90 cm of moist to wet snow and three prominent crusts (buried January 10th, January 8th and January 7th respectively). While these crust remain easily identifiable they have been unreactive in recent snowpack tests. The snowpack depth at 1000 m is now about 200 cm.
