NE / Moderate: 17-25 mph
Today I toured around Ball Butte and Broken Top. The 10 to 15cm of snow we received in the last 48 hours appeared to be well bonded to the old snow surface and 2/22 rain crust where previously exposed. A compression test below Ball Butte's NE ridge gave me a CT22 Break fracture quality at 20cm down. Below the 2/22 rain crust the snowpack looks strong. While skiing east and west aspects on both Ball and Broken Top I saw no cracks while ski cutting, heard no whumphing, saw no signs of recent avalanche.
Of interest today was moderate to strong winds coming from the NorthEast across ridge tops. Westerly winds had transported snow to easterly aspects on Thursday. Today easterly aspects became fetch zones for snow transported to the SouthWest. Climbing Broken Tops SouthEast ridge I saw the formation of small shallow isolated windslabs on south aspects.. Certainly snow is being transported and any new windslabs should be approached with caution. See Pics.
Today at 11:45 the top of "A La Mode" winds where moderate to strong from the Northeast, skies clear, air temp -1c (30f). I did see some pin wheels created by falling ice in the bowl as I was leaving at around 2pm.
Another great day of skiing :)
