The Zanavoo Gully in lower Logan Canyon naturally avalanched today. Reported at around 13:00.

The heavy dirty and tree filled debris ran way down into lower elevations.

I was able to get a view of the starting zone. Looks like the avalanche started as a deep slab but picked up weight and rapidly became a wet avalanche.
