The well-preserved NSF layer is easily seen in this profile, buried beneath recent storm snow. I'll refer to the NSF layer as the "2-11" interface, as it was buried on the night of February 11th. The 2-11 interface seems to have adjusted to recent loading, and I didn't find it to be very reactive in my travels today. You can see the ECT results from this pit. I also dug a pit at a similar aspect and elevation on Julie's backside and got ECTN 13. Very consistent results, but not all that alarming. It will take some amount of wind drifting to get this layer to fail. As you enter the upper reaches of the near treeline zone, you will encounter drifted snow, and this layer will be more reactive. Clear skies are in the forecast for Thursday, and I suspect it will be a good day for viewing recent avalanche activity near treeline and above.
