Rising out of the arid Mexican Desert lies a 900ft ship's prow of elegant limestone, sporting a 9-pitch 5.13 established in the 90s by Jeff Jackson. A cutting-edge Big Wall free climb at the time, this climb shut down hard men for years. Shrouded in mysticism, the bolts rusted and the holds collected dust, until a couple of gals from Canada decided to give it a try.

An expedition to an unclimbed seacliff in Greenland includes hundreds of miles of arctic kayaking and iceberg dodging – and that's just to get to the base of the wall, where the real adventure begins.
