Route Notes	After the big snowstorm [Sept 25-27], we had a number of members depart on Sept 27 from both teams due to the bad conditions on the mountain and commitments back home (unable to wait for the conditions to improve): Don Larson departed early from Shishapangma (high point was C2). Cho Oyu members departing early (high point was C2): Craig John Daniel Khouri Caroline Meyer Steven Meyer Shawn Peet Carlton Swan Marcus Bridle Lisa Amatangel Walter Laserer Heidi Sand Alois Feichtinger After the 11 left Cho Oyu on the 28th, 3 of the team Cho Oyu members elected to stay longer to try to climb: Ping Huang Kumaran Rasappan Max Bunce They went to C2 on Sept 29 and tried to go to C3 on Sept 30, but still too much snow, so they pulled the plug and descended to ABC. Departed next day (Oct 1).
