Cho Oyu International Winter Expedition

A fast-moving alpine-style climb by three pairs took advantage of the fine weather of the first week of December to tackle Cho Oyu by the Nangpa La and the SW ridge. The Czech pair reached the summit (8,222m); the Canadian pair (Burgess and Marshall) retreated at 7,500m, and the US pair at 7,000m. This fastest ascent of a 8,000m peak in winter involved a high element of risk.
