In 2013, Elia Saikaly recorded hist entire ascent of Mt. Everest in HD video. The result is an incredible first person view of the challenges that face climbing parties amidst breathtaking scenery. Having read a number of accounts of the climb, I’ve built a mental image of various parts of the mountain but here you can clearly see milestones fo the climb and get a sense for how they affect the climbers. You can feel they tension of the Hillary Step and see why it is (was?) such a bottleneck with an infamous history.
