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.

Everest's west ridge also did not seem encouraging from this location so Mallory decided the West Rongbuk glacier should be explored.
