yesterday afternoon we were climbing
Chris's Arete (HS 4b) at
Kyloe Crag (Kyloe Out) and a head sized block came off in my second's hand.
It was at end of first section of the climb before you move left onto the second part of the arĂȘte. The gap left by it is clearly visible from the ground.
We did not have time to check if the remaining rock was stable. care required.
