Leaves Numbah Ten after the 6th bolt and heads right through a roof and onto a technical arete that is just under vertical (.13c).
An extension (F.A. Ben Gilkison, 2007) continues above the anchor over the roof past one bolt and ends at an anchor on a ledge (.13d). Natural gear is needed for this extension.
Location
One 70m rope reaches the ground from the top anchor; otherwise a 60m is sufficient. Route starts as for Numbah Ten in an obvious groove left of Iron Horse.
Protection
13 quickdraws plus anchor; one more quickdraw plus small nuts/tcu's for the extension.
