All scenarios
Alpine scramble, class 4 ridge. Late afternoon.
The Loose Block
The setup
You're moving unroped along an exposed class-4 ridge with a partner 20 feet behind you. You test a refrigerator-sized block for a handhold. It shifts — the whole thing is loose, balanced on rubble. If it goes, it goes down the gully your partner is standing in.
