I wonder if you can elaborate on the details of what fell off.
Having done this route many times, I am a bit puzzled as to what fell off.
From Bonfire ledge, I assume the huge white flake which goes up and right leading to the highest stance, just before the semi-corner, is still intact. From the highest stance, you would make a reach for the bomber crack, and step over to the steep slab, to the right of the crack.
I assume what fell off, is perhaps some rock, right in the corner, just to the right of the big white flake. The rock in the corner was less compact, and that block which people stood on, to reach the crack, used to be even taller, but many years ago, part of it fell off, making the move harder to reach the crack.
I will get up there and take a look, as I wanted to do the route again anyway.
I would feel bad, if this new rockfall put climbers off from doing the route in the future, due to poor protection.
Perhaps this is a rare case where a bolt needs to be placed in order to make the pitch "safe". I would NOT place a bolt until
consulting with other forum members.
