Colibasanu and Hamor were back at Advanced Base Camp last week, after facing poor snow conditions along a couloir leading to the West Ridge.
On May 20, they descended further to Base Camp itself, and yesterday announced that they have abandoned their expedition due to unfavourable conditions on the mountain.
The Romanian-Slovakian duo intended to climb the Hornbein couloir, which has only been ascended, in part, five times since the original 1963 American expedition.
