The bottom end of the couloir drops to the south face of the mountain, and it gradually steepens to 60 degrees just below the ice field. It is not possible to climb up the icefield, which rises straight up tens of metres; instead, one has to traverse leftwards at the bottom of the icefield 100 m (330 ft) until it is possible to pass it.
The following is a list of rock types recognized by geologists. There is no agreed number of specific types of rock. Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe a rock type. Additionally, different classification systems exist for each major type of rock. [1]
The list includes 4 of the 14 8000m summits, all in the Karakoram, including the second highest mountain in the world, K2. There are a further 19 Ultras in the Karakoram and 5 in the Hindu Kush over 7,000m. The ultras of the Himalayas lie to the south east and are listed separately. To the north are the Pamirs, and to the east the mountains of ...

Elemental iron is virtually absent on the Earth's surface except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths.Although iron is the fourth most abundant element in Earth's crust, composing about 5% by weight, [4] the vast majority is bound in silicate or, more rarely, carbonate minerals, and smelting pure iron from these minerals would require a prohibitive ...
