Incredible skiing in the glades on Saturday between Syncline and St. Eloi. Pack is still thin with plenty of hazard, and more southerly aspects as well as ridge crests are blown pretty bare. East/Northeast aspects had a 60/100cm snowpack depending on where you are. Snowpack was solid and the new snow from last Sunday and Friday was extremely light and dry, it was hard work breaking trail. Conditions were blower. Watch out for for this storm layer if the winds pick up and/or it becomes more cohesive.

The new storm snow failed on a layer from last week about 40 cm down, failure was HCT21. The break was a sudden pop but would not propagate on the extended column test. Our pit was dug in a lee feature that would have been susceptible to wind loading, but we found none. The day was calm with occasional gusts but the new snow till clung to the tree branches (a rare sight in Southern Alberta) and there was little evidence of significant transport. Surface hoar was beginning to grow from the cold temps and could cause problems in the future. On average the depth was 80cm, but ridges were quite thin with many hazards exposed, concavities and thin trees on east aspects provided by far the best skiing.
