Sluff on Fin and grizzlies on Sheep

Cookes' always interesting in the spring, deep slab goes to sleep and the Grizzlies wake up. Curious how she knew to thread the cornice just right(Sheep Mt). Second Pic is a large sluff on the Fin, couldn't quite make out the track route till I drove to Silver Gate. He skied the hanging gully to the east of the third pic and rock climbed across the cliff to this sluff and tracks... Don't ask how I know it was a grizz, no time to get a pic.

Notes

From obs on 04/17/2024: "Wet slab 150-200 ft across, SE shoulder of Abundance towards Wolverine. Looks to have maybe happened before new snow. New snow 6-8 was extra funky, 2-3 powder on a rain? crust on heavy wet. Bonded to unsupportive melt freeze on completely saturated glop. Lots of short running sluffs"
