The northeast ridge route begins from the north side of Everest in Tibet. Expeditions trek to the Rongbuk Glacier, setting up Base Camp at 5,180 m on a gravel plain just below the glacier. To reach Camp II, climbers ascend the medial moraine of the east Rongbuk Glacier up to the base of Changtse at around 6,100 m. Camp III (ABC - Advanced Base Camp) is situated below the North Col at 6,500 m. To reach Camp IV on the north col, climbers ascend the glacier to the foot of the col where fixed ropes are used to reach the North Col at 7,010 m (23,000 ft). From the North Col, climbers ascend the rocky north ridge to set up Camp V at around 7,775 m. The route crosses the North Face in a diagonal climb to the base of the Yellow Band reaching the site of Camp VI at 8,230 m. From Camp VI, climbers will make their final summit push. Climbers face a treacherous traverse from the base of the First Step, to the crux of the climb, the Second Step.  Once above the Second Step the inconsequential Third Step is clambered over. Once above these steps, the summit pyramid is climbed by means of a snow slope of 50 degrees, to the final summit ridge.
