"Last evening brought us to the moment when the rescue party, having entered Volcano Bay, were about to land at the foot of the great mountain, called Olympus--the Hili-li synonym for Mount preceding the name Olympus when the peak, some eight miles high, was referred to. Now if you will examine this map with a little care you will observe here, near the inner extremity of Volcano Bay, an apparently narrow inlet passing directly into the mountain-side. This does not represent an inlet from the bay, but an outlet from Crater Lake, a very deep lake, the surface of which is several thousand feet below its banks, the lake being on the top of the mountain, just south of Mt. Olympus, and emptying into Volcano Bay. This outlet is a small stream at the bottom of a chasm which cannot correctly be represented on my map, as it is relatively very narrow, being only from ten to one hundred feet in width. This chasm is what we here term a canyon, or _cañon_, the walls of which in this instance rise perpendicularly from the water to the average height of ten thousand feet. The paths up the mountain are on the sides of this outlet--not close to the water, but winding in and out along the mountain-side above, there being a passable way on each side of the canyon from the bay to the lake, the distance from bay to lake along either path being, in its tortuous course, about thirteen miles. At Crater Lake the mountain rises to a height of about six miles, the surface of the lake being about four miles above the sea level, its banks some ten thousand feet in height. A perfectly straight line down the mountain-side would measure about eight or nine miles. "As the canyon leaves the bay, its walls are about a hundred feet high, and are separated by about the same distance; but as the mountain is ascended, the walls rapidly rise, and soon become far above the water between, and they gradually approach each other. At certain points the walls actually overhang the stream below, and almost meet, at one spot approximating to within ten feet of each other. Three miles from the bay the walls are twenty feet apart, and for the remaining five miles they do not at any place approach closer, but on the other hand very gradually separate to about sixty feet at the extreme top. At five miles from the bay the walls are fully ten thousand feet in altitude, and are nowhere less in height from that point to the edge of Crater Lake.
