I intentionally ski cut a mid-slope steep roll-over on a terrain feature in the storm snow. Primary contributing factor was a significant increase in slope angle with warming/greenhousing perhaps fostering more "slab characteristics" and propagation potential than in other observations along the way. Weakness was density change just 8" down within the storm snow. No other signs of instability noted along the tour other than clockwork warming/dampening of new snow on exit back into Big Springs.
