Climb Gasherbrum II

The Savage Mountain: 8,611 m, harder and deadlier than Everest, with no easy route to the top.

The Killer Mountain: 8,126 m, with the Rupal Face, the biggest mountain wall on Earth.

Hidden Peak, 8,080 m, buried so deep in the Karakoram it cannot be seen from any inhabited place.

Twelve kilometres from K2 at 8,051 m, with a long summit ridge that has cost several lives.

The third-highest mountain on Earth, sacred enough that climbers stop a few metres below the true summit.

Everest's neighbour at 8,516 m, sharing the Khumbu Icefall and the South Col before splitting away.

A near-perfect four-sided pyramid of 8,485 m, one of the hardest of the fourteen.

The White Mountain, 8,167 m, thought to be the highest in the world for thirty years after 1808.
