We did not know what the face had to offer, but to our relief found it very climbable. We were able to link-up class 4 snow and rock ramps. At one point a 20 meter high rock band of loose and vertical rock split these ramps. Liu Yong efficiently surmounted this obstacle and we continued following the ramps up the face to a slightly overhanging snow cornice. I dug my way through the cornice which led onto the glacier.

Lava from the earth's crust deep place, because the earth's crust deep place's temperature is extremely high, the lava by the volcano rock magma's shape existence, along with the volcanic eruption, the rock magma also spouts the surface along with it, meets the water or the low temperature starts to congeal, because the congealment process air entry, turned solid the rock magma to form the massive air bubbles gradually in the interior, coagulated after completely, has formed the structure unique lava.

火山石来自地壳深处，由于地壳深处的温度极高，火山石以火山岩浆的形态存在，随着火山喷发，岩浆也随之喷出地表，遇到水或低温开始凝结，凝结的过程由于空气的进入，逐渐变成固体的岩浆在内部形成了大量的气泡，完全凝固后就形成了构造独特的火山石。
