Classic bouldery sit start on technical arête. Lie back arête low while utilizing giant side pull jug out left until it becomes possible to heel hook on left side pull jug and clear the lip to the mantle.
Ok landing, kind of a but buster on rock behind you. With a couple pads it's not bad at all.
SW Passage is the obvious short arête that makes up the back right side of El Corrádor.
This would also be the South West arête of the Little Brother.
Sit start low and climb overhanging left side of arête.
