The Route of the Mount Everest Expedition.

The expedition made its way almost due west behind the main chain of the Himalaya, until one evening its members saw, almost due south of them, a beautiful peak which was apparently very high. The natives called it Chomo-Uri, which means the "Goddess of the Turquoise Peak," and from observations next morning it was clear that it was Everest. They passed some wonderful monasteries perching on the face of perpendicular crags, and eventually, on 19th June, they reached Tingri Dzong, after a month's travelling from Darjeeling. This was the spot they had decided upon for their base camp.

The obvious route to Everest seemed to be by way of the Rongbuk valley, where the great Rongbuk Glacier flowed from its northern face. There, accordingly, the two climbers, Mr. Mallory and Mr. Bullock, established themselves. The preliminary reconnaissance, however, proved to be a somewhat intricate matter. It was soon plain that there were no easy approaches from the west, so Colonel Howard-Bury moved his headquarters to Kharta, on the east side, close to the Arun. That river, which there is about one hundred yards wide, a little farther down enters great gorges, in which, within a course of twenty miles, it drops from 12,000 feet to 7,500 feet, or over 200 feet in a mile—a far more wonderful spectacle than anything on the Brahmaputra.

On 2nd August, Mr. Mallory and Mr. Bullock started their exploration of the eastern approaches to the mountain. This was no easy business, for the valleys were separated by ridges, the lowest point of which was higher than any mountain in Europe, and every route had to be explored personally, for no information could be had from the natives. The two main valleys running down on the east side of Everest are the Kharta and, farther south, the Kama. The latter valley was first explored, and it was found that it ended under the precipitous eastern face of the mountain, and that there was no way from it of reaching the North-East ridge. It was a marvellous valley for scenery, but for mountaineering impracticable.

A move was accordingly made to the Kharta valley to the north. Mr. Mallory and Mr. Bullock proceeded up this till they reached the glacier of the Kharta River, and at last found a valley which seemed to lead them straight to the North-East ridge. It was now, however, early August, the monsoon was blowing, and everywhere there was deep, soft, fresh snow. They returned accordingly to the camp at Kharta to wait till weather conditions became better.

What was called the Advance Base Camp was established in the Kharta valley at a height of 17,350 feet, in a grassy hollow well sheltered from the wind, and amid a glory of Alpine flowers. Meantime Mr. Mallory and Mr. Bullock spent their time in carrying wood and stores to a camp higher up the valley. This was finally established at a height of some 20,000 feet, well up the Kharta Glacier. At the glacier head was a pass called the Lhakpa La, or "Windy Gap," and the next step was to form a camp there at a height of 22,350 feet. It was in this neighbourhood that the tracks, probably of a wolf, were found, which the coolies attributed to the "Wild Men of the Snows."

From the Lhakpa La the mountaineers were now looking straight at Everest, and at last were able to unriddle its tangled topography. The attention of the reader is called to the map. It will be seen that the great Rongbuk Glacier, which descends from the western side of the northern face, receives as a feeder the East Rongbuk Glacier. The entrance to the latter is so small that Mr. Mallory and Mr. Bullock had failed to notice it in their exploration of the main glacier. This lesser Rongbuk Glacier ends on the eastern part of the northern face of the mountain, and between its head and that of the main glacier is the pass called the Chang La, or North Col. From the Lhakpa La one looks into the East Rongbuk Glacier with the North Col straight in front. If the North Col could be attained, it seemed to the mountaineers to be possible, by working up the easy northern face, to attain the North-East ridge at a point above the main difficulties.

The camp on the Lhakpa La was not a comfortable place, with a howling wind, 34 degrees of frost, and little stuffy tents which gave dubious protection and inevitable headaches. It was decided that the two expert Alpine climbers, with a few picked coolies, should alone attempt the North Col, and, if fortune favoured, prospect the farther route, while the others returned to the 20,000-feet camp.

We are now concerned with the doings only of Mr. Mallory and Mr. Bullock, who were to attempt the North Col. In the weeks since their arrival in the neighbourhood of Everest they had been studying its contours with the eyes of trained mountaineers. They saw that it was a great rock mass, "coated often with a thin layer of white powder, which is blown about its sides, and bearing perennial snow only on the gentler ledges and on several wide faces less steep than the rest." They saw that from the point of the North-East shoulder a more or less broad arête fell northward to the snow col called the Chang La. If they could reach that snow col the road to the North-East ridge looked reasonably simple. They had seen that the Chang La would be very difficult of attainment from the Rongbuk Glacier, and that was why they had turned their minds to an eastern approach. Here is their conclusion, in Mr. Mallory's words, reached about the third week in July: "If ever the mountain were to be climbed, the way would not lie along the whole length of any one of its colossal ridges. Progress could only be made along comparatively easy ground, and anything like a prolonged sharp crest or a series of towers would inevitably bar the way, simply by the time it would require to overcome such obstacles. But the North arête, coming down to the gap between Everest and the North Peak, Changtse, is not of this character. From the horizontal structure of the mountain there is no excrescence of rock pinnacles in this part, and the steep walls of rock which run across the north face are merged with it before they reach this part, which is comparatively smooth and continuous, a bluntly rounded edge.... The great question before us now was to be one of access. Could the North Col be reached from the east, and how could we attain this point?"
