The results of this first Swiss expedition to Mount Everest were remarkable, and exceeded even the most optimistic expectations. At the first attempt, it had opened up a new route to the peak of Everest, and it had reached an extraordinary height on the southwestern ridge in difficult conditions. In the opinion of the extremely critical Marcel Kurz, this expedition was almost a victory.They had seen from closeup that the route to the South Summit had no insurmountable barriers, and only the last to the summit remained unknown. The spring expedition might have reached the summit using the Draeger oxygen sets used for the autumn expedition. They established for the British that in 1953 the route should be up the Lhoste Face not the couloirs, and have a high camp(s) on the South Col (which meant more stores to be carried higher). See Appendix for comparison of the two expeditions.
