There is the usual plaza in the centre of the town, where the youth and beauty disport themselves in the way peculiar to these mountainous regions, which consists of walking round and round at a good pace to keep up the circulation, as the weather is nearly always cold in Sorata. Illampu, the competitor of Illimani and Aconcagua, and which claims to be the highest peak in South America, rises up magnificently right above and round the town, and visitors for the first time must really wonder how they are to find a road to cross these gigantic mountains, as the town appears to be so completely shut in. However, on 27th May we started to ascend the track forming the way to the interior, and got a fine send-off by the inhabitants, the more important of whom turned out to bid us adieu and wish us luck over a case or two of beer. The climb before us was a constant one for 18 miles, and to-day we were to pass the highest point of our entire trip. This we reached about midday, at just under 16,000 feet. We were above the perpetual snow-line for a short time, and it was piercingly cold, besides we had to go slowly on account of the thin air, but we kept steadily on and reached an old mining establishment called "El Injenio" at 5 p.m., having done 24 miles in all since morning. There is a long, steep descent to the old mining camp by a narrow winding track cut out of the mountain side, and as the drop on one side to the little stream down below was about 40 to 50 feet, and there was no protecting fence of any kind, we decided to get off our mules, and accordingly completed the worst part of the way on foot, and of course this made travelling very much slower. Apparently, gold-washing had not been carried on for a very long time, as although the main building still has a roof, the whole place has a very deserted look about it; but, nevertheless, it still affords a covering for weary travellers like ourselves, and we soon began to select the most comfortable looking corners for our beds. There was an old Indian there who earns a meagre existence by selling forage to passing travellers for their beasts of burden; and he was also utilised by us for getting a fire ready and boiling water for a welcome cup of warm tea.
