Friday, 6:20 am local time (Thursday, 9:20 pm EST). We have not yet heard from our climbers but at Base Camp we have received visits from the Portuguese, Italians, Koreans and Russians in the last 30 minutes. From what we can piece together, the Americans and Koreans left first this morning. Followed by the Italians around 2 am. The Russians and Portuguese Teams departed Camp 4 around 3 am. Gauging by the speed of the Americans from Camp 4 to the bottleneck, all of the teams are likely within 150 meters of each other at this still early stage.
