Snowpack Summary

2 to 5 cm of new snow redistributed by moderate to strong winds varying from the SW, S and SE aspects. We suspect that the melt freeze crust of variable thickness on the solar aspects and below 600m has limited the effects of these winds on the snowpack surface. Under this thin melt freeze crust, 10 to 20 cm of slightly denser snow rests on the March 18 crust. The middle of the snowpack is well consolidated, and of increasing density, interspersed with several refreezing crusts from the last few weeks.
