Winter has definitely arrived and the 4th avalanche course of the season concluded with a very interesting day in the Ravine. Light density snow from the higher summits has accumulated into pencil hard wind slab with varying thickness, all sitting on top of a thick melt-freeze crust from last week’s thaw.

At the end of the day we got some nice turns in some fresh powder before taking the Sherburne trail back to Pinkham. Couple spots left for next weeks course! http://www.emsclimb.com/aiare1.html
