The slope is steep and mostly devoid of snow, making it harder to pile rocks to create a level platform the full size of a tent.
The first camp is established at the North Pole at 7000m whereas the second camp is at 7800m on the rocky ridge. Camp 3 is above 8000m at an elevation of 8300m which is on a broad, steep, rocky face below the northeast ridge. The slope is steep and mostly devoid of snow, making it harder to pile rocks to create a level platform the full size of a tent. So the level of difficulty of the Mount Everest Expedition is also high from this side.
