Annapurna IV Attempt and Medical Expedition. A French expedition led by Philippe Paumier of the Association pour la Recherche en Physiologie de l’Environment was composed of 12 climbers and three others, mostly doctors who wanted to carry on high-altitude research while climbing the normal northwest route of Annapurna IV. They had hoped to set up a laboratory at 6350 meters, but bad snow conditions prevented their making any camps above Base Camp. Five members carried loads to 5000 meters on October 6 and 7.
