The low angled route ~10m left of large tree

FA: Erik Ferjentsik, 2007

Small holds requiring enduring power.

FA: Steve Bradshaw, 2011

FFA: Steve Bradshaw, 2011

6c+ ** Bolts 'R' us Sport 16m, 8

FA: Nicola Gatti, 2008

6b * Argentina's Delight Sport 29m, 13

Easy arête climbing (shared start with Flight of the Bumblebee and Mother butterfly) leads to a crack on the left. May be extended into Place Your Nuts Right for another 12m, but requires an 80m rope or two rappels.
