As I lead this climb, Calypso, in a cold drizzle, my thoughts are on the bad rep this pitch has. From the guidebook - "The park rangers reckon P1 to have more accidents than anywhere else in the Canyon. The traverse at the end of P1, once protected by some old pins, is now difficult to protect and pretty polished. A fall by the leader from the end of the traverse can result in a nasty swing back into the dihedral. Competence required."
