Snow depth is typically 80-110cm at treeline with 60 to 70cm of well settled snow sitting on the October crust located just above the ground. Little is known about the bond to this crust; however, limited reports suggest that it is currently well bonded. The snow surface on sun exposed alpine slopes, and all slopes below treeline, has been subject to daily melt-freeze cycles. Large surface hoar has also formed on all aspects. Although it has been melting on south aspects during the day, it has likely been regrowing overnight. If you are traveling in the mountains, now is a good time to make note of these surface conditions which may become persistent weak layers once buried by a sufficiently cohesive slab.
