Amongst the general public, Mount Everest will always be “the mountain” – a place that is fascinating and amazing. However, among mountaineers, “the mountain” will always be K2. This is no slight to Everest – it will always be one of the seven summits, and it will always be the world’s tallest mountain. But in 2015, while Mount Everest remains a challenge because it is the tallest mountain on the planet, it also is a place where many of the challenges have been minimized due to the proliferation of professional guide services, and “mountain tourism”. While K2 has experienced some of the changes in the field of mountaineering, even today it remains one of the most dangerous climbs a mountaineer can undertake.
