I suppose this break may be taken as the forerunner of the monsoon on Mount Everest. Storms there may have been before; but, generally speaking, it had been fine over the mountains since the beginning of June, and though the evidence is slight enough it seems probable that Everest received little or no snow before June 20. When first we saw it, a few days later, from the Rongbuk Glacier, it was still comparatively black. It appeared a rocky mass with a white arm to the right, some permanent snow on the ledges and in the gullies of the face turned Northwards in our direction and some snow again on the high North-east arete; but with no pretensions to be a snow-mountain, a real sugar-cake as it seemed afterwards to become. We were lucky in having a few fine days at the outset of our reconnaissance. The conditions then were very different from those which obtained later. The recent snow must have melted quickly; we found clean ice on an East-facing slope at 21,000 feet and also at a gentler angle on one facing West. On Ri-ring the slopes were generally covered with snow near the crest, thinly but sufficiently, or we should never have got up; near the summit we found ice on both sides, North and South. It is impossible to say up to what height one might have found ice in June. Appearances suggested that on all but the steepest slopes above 23,000 feet the surface was hard snow rather than ice. It was on the day following our ascent of Ri-ring, July 6, that we first experienced a real snowfall; and we woke next morning to find 3 or 4 inches covering the ground. In so far as an exact date can be ascribed to what is hardly a single event, July 6-7 may be taken as the beginning of the monsoon. We imagined at first that this snowfall was an important matter, sufficient to prevent climbing at any considerable height for several days. But from subsequent observations we came to treat such snowfalls with a certain degree of contempt. It was more often than not the case during the whole of July until the date of our departure that snow fell during the day--sometimes perhaps for a comparatively short period between noon and sunset, not seldom for many hours, intermittently during the day from the middle of the morning, and continuing into the night. But it was often so far as we were concerned a harmless phenomenon. Snow was precipitated from clouds so thin that they were easily penetrated by the sun's heat; it melted where it lay, and the moisture so readily evaporated that the snow had hardly stopped falling before the ground was dry. One might suppose that a few hundred feet higher, where the snow could be seen to lie where it fell, the effects would be more severe; but it was remarkable after half a day's unceasing precipitation of this fine granular snow that one might go up early next morning, perhaps to 20,000 feet, and find no more than a thin covering of 2 or 3 inches on the stones.
