Along the frozen river between base camp and Camp I, for example, there are over 20 crevasses and icefalls; between Camp III and Camp IV, the entire way is lined with sheer ice and rock cliffs. Camp III itself is built on an icy slope with not an inch of level ground.
以基地營到第一營的冰河段為例，就有二十多處冰河裂隙和垂直大冰瀑；第三營到第四營間，則是一連串的陡坡冰壁和巨大岩壁，第三營營地甚至是建立在有沒一吋平地的冰坡上。
