    Extreme south/southwest winds Tuesday night redistributed snow in exposed terrain in the alpine and at treeline. Assess the snowpack as you go, looking for these stiff deposits of snow.

    Be aware of large cornices overhead, or as you approach/walk along ridgelines. There have been several close calls this week, with people getting too close and luckily not being taken with the collapsing mass of snow.

Snowpack Summary

A spring snowpack exists in the park, with some new snow at higher elevations and a mix of crust and loose snow elsewhere.

The Feb 3rd crust/facet layer persists 80-140cm down. The mid and lower snowpack is well settled and strong with a record low depth of snow of ~210cm at tree line.
