Route Notes	13 May midnight left C2 on summit push and 14 May on top alone: followed crampon trail of American and Spanish in foggy weather to top where trail stopped and waited for fog to lift; it lifted but but Everest in clouds. American leader Wedberg said they had seen Everest an hour or so before at top. Returned to C2 5:30 pm. Exposed rock from C2 to C3 ice and seracs. Moretti went no higher than 6050m and very sick and returned to ABC and stayed at ABC for rest of time while Vielmo on mountain. Wedberg - 21 May US leader Wedberg when descending from summit met Vielmo above plateau's shoulder and gave him water and candy. Vielmo seemed Ok going towards summit.
