THE GREAT ASH SLIDE OF SLIDE MOUNTAIN Our experience in taking this picture furnished an amusing example of our inability, even accustomed to stupendous dimensions as we were, to form any real conception of the size of the wonders by which we were surrounded. Desiring to have a scale by which the size of the slide could be gauged, I sent one of the men up on it for that purpose; but, to my astonishment, when he emerged from the forest and began to climb up the slope I could barely make him out, much less find him in the resulting picture. Our triangulation gave it a height of nearly 1,900 feet (see text, page 34). hind a foothill, which, from its position, we named Observation Mountain. Next were the three peaks of Mount Mageik (see page 32), covered with newly fallen snow. Across its northwestern slopes formerly ran the trail to Bering Sea, across Katmai Pass, which, though re puted difficult and dangerous, looked very easy from our position. On the northeast side the pass is flanked by a lofty three-peaked volcano, which we called The Trident (see page 65). Its three peaks are arranged in semicircular fashion, leaving between them an amphitheater open toward Kat mai Valley, which looks somewhat like an ancient crater breached on one side. The highest peak appears from the valley like an almost perfect cone, truncated at the top as though by a crater. Its height as given by the chart is 6,790 feet. The present crater is a fissure at the base of this peak (altitude about 3,500 feet), from which issued, somewhat in termittently, a column of steam. Al though the volume of this steam was quite small in comparison with that of Mageik and Martin, it sometimes as sumed quite respectable proportions, ris ing 3,000 feet or more. There is good reason to believe that this vent also ap peared in connection with the great eruption. OUR FIRST SIGHT OF MOUNT KATMAI Next in line beyond a wide pass stood Mount Katmai itself. This was quiescent during our visit and at first sight pre sented a rather disappointing appearance, for its glaciers and snowfields were so covered with ash as to make it suffer from comparison with Mount Mageik. As we studied it, however, we saw that its great bulk reduced its apparent height.
