THE LOWER ROSITTEN ALP AND THE UNTERSBERG.
The bottom of the Korridor was filled with blocks of fallen limestone, through which any water drains off, and on which there was a wooden walk, so that we circled round the ice with the greatest ease. At one place on the limestone wall hung a cluster of big icicles, which, from their shape really deserved the name they bear, of the Orgel. At another place a hole, some six or seven meters deep, was hewn, in the form of a small chamber, directly into the ice mass. This is the Kapelle, where we performed our devotions by leaving our visiting cards on the floor. Near the middle of the Korridor the ice mass bulges out and extends to the limestone wall, breaking the whole Korridor into two parts, the western portion about eighty meters, and the eastern about one hundred and twenty meters long. This necessitated cutting a tunnel about eight meters long in the ice to get through. The color of the Korridor is a darkish gray and is much more sombre than that of the Grosser Saal. A remarkable feature of the ice wall is the fact that distinct bands of stratification are visible in the ice in many places. Why the Korridor is not filled up with ice and why the ice is perpendicular for such a distance are questions I am unable to answer satisfactorily; but it is probable that the temperature of the rock walls is sufficiently high to prevent ice from forming in winter or to melt it in summer if it does form in winter.
The air in Dóbsina seemed still, and scarcely felt damp. In one or two places in the Grosser Saal there was a slight sloppiness, showing incipient signs of thaw. In the Korridor it was freezing hard.
THE KOLOWRATSHÖHLE.
The Kolowratshöhle is situated on the north slope of the Untersberg, near Salzburg, at an altitude of 1391 meters. My brother and I visited it on the 2d of August, 1895. We had one of the patented guides of the district, Jacob Gruber by name, in regular Tyrolese dress, with gray jacke and black chamois knee breeches. We left Salzburg in the early morning in an einspänner and drove to the foot of the Untersberg in about an hour, whence, by a rough path passing by the Rositten Alp, we ascended to the cave in about three hours. The last hundred and sixteen meters of the path were cut across some moderately steep rock slabs and a perfectly unnecessary iron hand-railing affixed.
The entrance faces northeast. Here there must have been a slight draught of cold air moving outwards, the effect of which was perceptible to the eye, as at the point where the cold inside air met the quiet warm outside air, a faint mist was visible. From the entrance, a sharp slope, set at an angle of about forty degrees, led to the lowest point of the cave. The upper half of this slope was still covered with the winter snow which had blown or had slid in. We descended on the right hand edge of the snow by means of some steps cut in the rock by the Deutschen-Oesterreichischen Alpen Club. These steps were covered with a sticky, red mud, which left almost ineradicable stains on our clothing, and as there was also ice in places, they were decidedly slippery.
