Once back in Huaraz, we regrouped and departed to our next peak, Pisco. Now acclimated, we moved straight to high camp (15,500’). We awakened at 2pm to being our ascent and made quick progress to the toe of the glacier. However, I was laboring. My stomach started feeling all-too-familiar, so I dropped the rope and returned to base camp, while Jay and Luis proceeded to the summit successfully. I spent a miserable day getting violently ill and increasingly dehydrated near camp.
Jay and Luis returned just in time to meet our burro driver (arriero), who was to help us bring our gear down to the lower camp. They stayed with the gear and I proceeded to descend to camp on my own. I was so dehydrated though that I would lose track of where I was, and I hallucinated seeing a Kodiak brown bear (in Peru of all places), which was frightening in the moment, as well as some US Special Forces camouflaged backpacks that turned out simply to be ornate rocks.
