1050m. Excellent route on sound rock but for the chimney pitch below the Jammed Block.
Below the 90m corner it has not been affected by the rockfall, but the lower slabs are still a dangerous place to be on daytime.
From the top of the 90m corner is possible to do an A1 traverse and reach the N Face route, thus avoiding the top pitches which run next to the rockfall and is said to have loads of loose rock.
It is also possible to rap straight down from the same point.
