returned from three days at Ashman. 18th: Clear and calm day, yielding significant solar radiation to S aspects. observed a series of size 2-2.5 avalanche debris on NE aspects (cornice or windslabs). good quality skiing was had on aspects unaffected by the wind. We found well bonding upper snow pack with no results on extended column tests on sheltered N, NE aspects at tree line. height of snow: >300cm @1450m, 230cm @1250m, 175cm @1100m. SE aspects had noticeable solar crust on the decent back to the Skylark. pinwheeling observed on steep S aspects. 19th: Woke up to clear and calm weather. Widespread surface hoar growth at all elevations and aspects (up to 1cm in shaded below treeline meadows). Winds picked up for two hours to moderate, with light wind transport at ridge top. These winds knocked down most of the surface hoar in exposed areas, although it was observable in sheltered areas below treeline unaffected by the sun. Snow profile on exposed N aspect slope with thin snow pack showed the significant melt crust/facet layer near the ground. This layer yielded moderate results in a compression test. 20th: Sunrise showed broken skies and light winds from the SW. 4cm of new snow at ridge top. In anticipation of incoming storm, and development of wind slabs, we skied steep NNW trees, and supported NNE aspect lines in the alpine. Near 10:30am, winds picked up to moderate, gusting strong at times and a lot of wind transport from the SW. Finished our day by 1:00pm so not positive on how extreme the wind came.

Snow conditions were: Crusty, Powder. Riding quality was good.
