Day 7 view from the 5000m San Antonio pass into the Quebrada Calinca valley. The glacier that Joe Simpson crawled down with his shattered knee is to the right of the frame. The valley that Shaun and I strolled down is to the left. And yes, the lake really is that colour.
Descending this pass on the northern side was scary and a bit risky due to the loose ball-bearing gravel/scree and the very steep angle.
