Came across fresh avalanche debris on the most Western slope coming off the Table Mt. plateau, adjacent to the small body of water South of Iceberg lake. Appeared as if it was triggered by a cornice failure. Photo attached, but difficult to make out the slide oath did to the flat light

Observations

Toured clockwise around Table Mountain in the Baler backcountry. Primarily overcast, with moderate E winds at ridge lines, increasing in the late afternoon. Occasional light snow showers.

Observed significant wind transport of snow. Wind affected snow was widespread, but easy to avoid. Hand shear tests in some areas resulted in easy failures at the interface between wind transported snow and the underlying low density snow. Shovel tilt tests consistently highlighted a density change in the new snow, but this layer was otherwise not reactive. In areas sheltered from the wind, we found seemingly bottomless low density snow.

Observed several crowns on the N aspect of Table, all of which appeared to be natural avalanches primarily from a day or two ago.

Avalanche debris at 5100’ W end of Table Mt. Appeared fresh, likely triggered by a cornice failure. Estimate D2 in size.
