North Col
Taking six days to acclimatise and recuperate they established Camp II at . On 1 July Mallory with five Sherpas went towards the head of the glacier near the North Face of Everest and at he was able to evaluate the western side of the North Col. There seemed to be no satisfactory way to reach the North Col but above there, and towards the summit, there seemed to be a feasible route. Everest's west ridge also did not seem encouraging from this location so Mallory decided the West Rongbuk glacier should be explored.
