Poor structure on Mt Ellis

Date
Activity
Skiing

Toured up Ellis today. Snow was starting to fall again in the late afternoon. HS varied from fairly thin below 7000 ft to about 110 cm at the top. We found supportable new snow and good skiing. Dug a hand pit at 7500 feet on a NE aspect and found about 50 cm of new snow sitting on facets over a melt freeze crust. At 8300 ft we did an ect on an E aspect and found a similar structure but had no results.
