Spent 4 days at the Fryatt Hut (Feb 21-24) over which we saw a general destabilizing trend. On Feb 22 (mainly cloudy) an attempt at the N Face of Xerses was thwarted by wind slab up to 20cm thick which was moderately reactive. We then climbed/skied the NW Coulior of Karpathos (Olympus) which had isolated wind slabs and significant spindrift/sluffing that increased with the growing PM winds. On Feb 23 we woke to ~10cm of new snow that continued through the day, perhaps 15cm total, with significant windloading in lee aspects. Groups checked out terrain near the Three Blind Mice zones while others enjoyed beautiful powder on southerly treeline aspects. Feb 24 we exited, and observed a significant avalanche (Size 2+) come down from near the summit of Fryatt NE3, possibly a cornice trigger. Feb 24 was cloudy with increasing winds noted in line with the forecast.
