Today, we woke up at 4:30am, ate a quick breakfast and left for Camp I. We stopped briefly at the deposit at 5000m to pick up some additional gear and then continued up the steep, icy slopes to Camp I (5700m). I arrived in 3.5 hours and the others followed shortly thereafter. As camp I is an extremely small camp, I arrived to find no vacant proper sites for the tent. I spent a half hour preparing a very small platform just beneath the route to Camp II and set up the small EV Direct tent, which just barely fit on the platform. After this Lina arrived and we spent the rest of the afternoon making water and enjoying the breathtaking views of the surrounding peaks. Once Pilar and Carlos had arrived, we discussed our plans for tomorrow. As I had arrived with no headache and feeling well, I decided that I will sleep tomorrow night in Camp II, while the others will simply make a deposit there and descend to sleep another night in Camp I.
