Climb Gasherbrum I

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.

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

At 8,035 m the most approachable of the Karakoram giants, first climbed in 1956.

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.
