Quick report
No sign of recent avalanche activity in my viewshed which included Powerline Valley plus NE and SW aspects of Flattop Mtn. Ski cutting of small roll overs produced 20cm wind slabs (pic). Considerble evidence of recent wind transport on ridgetops (pic). However SE aspect of Blueberry were not wind affected and made for pleasant skiing. Did a pit on the eastern margin of the historic Wind Tunnel slide path. No evidence of recent avalanche activity related to that path. Got CTN (profile attached). Did not observe any signs of recent instability in the snowpack other than small 20cm slabs produced by ski cutting rollovers (pic).
