I can confirm great skiing at Fraser with 45 cm of recent low-density storm snow (F-4F). We didn't find any wind effect where we skied(up to 1750m), and although there was some recent surface riming, it didn't detract from the ski quuality.
Travel at treeline remains challenging with a mainly unconsolidated snowpack, open creeks and partially buried alder.
Transitioning to the alpine, we found a variable 10-20cm thick layer of firmer (1F) previously wind packed particles below the storm snow. A thin 2 cm layer of lower density (4F) decomposing fragments could be found sandwiched between this and the November crust, (down 60-80cm). This layer failed with a sudden planar character under moderate results in compression tests but did not show propogation propensity in an extended colomn test (1500m, E aspect). We didn't encounter whumping or any other signs of buried instablity.
Even though we didn't find any wind effect, our primary concern for the day was the potential for isolated, small pockets of soft windslab in cross-loaded features and so we stuck to larger planar terrain features.
Definitely, the best early season turns I've had in the White Pass.
