Details of what exactly happened are still coming out, but it seems that the two Slovak climbers were hit by an avalanche at 7200 meters (23,622 ft) on the Southwest Face. The two men reportedly clung to a safety screw and a couple of carabiners for several hours before they were able to get themselves to safety. Now, they are headed back to BC to recover.
In other news from Everest, rope fixing efforts are now complete on the South Side of the mountain, with 11 Sherpas from various teams reaching the summit earlier today. Those are the first summits on the mountain in the past two years, an unprecedented streak for the world's highest peak. This now clears the way for the commercial teams to follow, with the first squads hoping to top out tomorrow or Friday. Meanwhile, back in Base Camp, other teams are now preparing to set out for the summit as well, with the weather dictating when they'll be able to move up.
The good news of the rescue on Everest was tempered reports of two Sherpa guides perishing on Makalu, apparently of altitude sickness. Da Tenji Sherpa and Lakpa Wangel Sherpa died in Camp 2 on that mountain after both complained of symptoms of HACE and HAPE. They were part of an 11-person Amical Alpin team. According to The Himalayan Times, the two men join two other Sherpas who have died of altitude sickness on Shishapangma, as well as two foreign trekkers in the Khumbu region near Everest.
In other news, Ueli Steck and David Göttler have returned to Base Camp on Shishapangma after being turned back due to poor weather conditions. Forecasts had called for a good weather window, but conditions changed quickly, forcing them back down. The two men are attempting a new route on the mountain, and say that they are far from done yet. They'll rest in BC and wait for better weather before attempting the summit once again.
