Beauty inversion at Fraser Peak

Weather: Started at -20°C car temperature and then hit an inversion at about 1200m and temps changed to t-shirt weather. Winds changed no wind to a light N wind around noon. Sunny above the clouds. Very poor vis on the decent once we hit the clouds. Snow: at higher elevations, above around 1500m, the new snow is starting to form a slab, that is sitting on surface hoar on the crust. We ski cut a feature on the ridge and caused a sudden planar 15cm down. Ski cuts at lower elevations caused no results other than scratching up my skis on rocks some more. We took a route around on the south side to avoid the north facing gully.
