Gasherbrum I

Gasherbrum I is 8 080 metres high and the eleventh highest mountain on Earth, and for a long time it went by a better nickname: Hidden Peak, because it hides behind its neighbours.

Where is Gasherbrum I?

Gasherbrum I is part of the Baltoro Karakoram.

You will find it in: Pakistan, China.

Summit: 35.724° N, 76.696° E

The story behind it

The British explorer Martin Conway gave it that name in 1892. Walking up the long Baltoro glacier towards the mountain, he found that the other Gasherbrum peaks stand in the way almost the whole time, and the big one only appears right at the end. A few decades earlier the surveyors of India had given it something far duller: K5, the fifth peak of the Karakoram, in the same list that left K2 with its number. Gasherbrum itself is a Balti word, and it means beautiful mountain — not shining wall, as you sometimes read; that nickname belongs to the face of Gasherbrum IV nearby. An American team reached the summit first, on 5 July 1958. Then, in 1975, Reinhold Messner and Peter Habeler climbed it in three days in what climbers call alpine style: no chain of camps, no porters ferrying loads, no bottled oxygen — just two people carrying what they needed. It was the first time an eight-thousander had been climbed that way, and it changed how people climb high mountains.

Find it on the globe

Gasherbrum I is there as a small peak with its own shape — a horn, a ridge, a volcano — standing on the surface. From far away the planet is only a blue ball; detail arrives as you zoom in, and this one appears once you are close enough. Open it on the globe.

It sits at its real coordinates, not near them — the same numbers listed in the facts above. Switch off the layer for this kind of place and it disappears again; the buttons for that are down the right-hand edge.

Questions children ask

Why is Gasherbrum I called Hidden Peak?

Because on the long walk up the Baltoro glacier the other Gasherbrum peaks stand in front of it nearly all the way, and it only comes into view at the very end. Martin Conway noticed that in 1892 and the name stuck.

What does Gasherbrum mean?

Beautiful mountain, in the Balti language spoken in the valleys below. You will sometimes read shining wall instead — that is a mix-up with a nickname for the face of Gasherbrum IV next door.

What is alpine style?

Climbing a big mountain the way you would climb a small one: straight up in one push, carrying your own tent and food, with no chain of stocked camps and no bottled oxygen. Messner and Habeler did it here in 1975, the first time on an eight-thousander.
