C3 at just below yellow band (Swiss C3).

25 April 1st summit attempt from C2 by Arbelaez, Barrios, Gonalez-Rubio; on top and back in 18 hours, on top at 14:30 NST (left C2 3:00 am; back in C2 at 18:30 hours). Only summiters on 25th from any expedition very windy on top where found Norwegians cross; could not see Everest through clouds. Next summit bid made after establishing C3 because too long distance without it and 25 April summiters very tired.

Next try for top on 29th from C3 but Ospina got cerebral edema just after left tent to go up so he and Cardona down instead and reached ABC same day and Ok.

Next attempt [5 May] from C3 now placed at 7500m by Cardona, Ariano, Ruiz and Camargo; Camargo only to 7550m and not feeling well (cerebral edema starting); left C3 at 0:30 hours and summit trio on top 7:30 hrs after 3/4 hour stop at 7800m in bad wind; very windy on top but very clean and saw Everest; back to C2 11:20 hours, C1 with Camargo and Cardona to ABC same day.
