My necessary delay at Camp 1 was utilized, so far as possible, in learning what I could concerning the adjacent country, and in making a beginning in the study of its geology. Our camp was at the immediate base of the mountains, and on the northeastern side of the wide plateau bordering the continent. The plateau stretches southeastward for twenty or thirty miles, and is low and heavily forested. The eastern shore of the bay near our first camp is formed of bluffs about 150 feet high, which have been eaten back by the waves so as to expose fine sections of the strata of sand, gravel and bowlders of which the plateau is composed. All the lowlands bordering the mountains have, apparently, a common history, and doubtless owe their origin principally to the deposition of débris brought from the mountains by former glaciers. When this material was deposited, or soon afterward, the land was depressed about 150 feet lower than at present, as is shown by a terrace cut along the base of the mountains at that elevation. The steep mountain face {83} extending northwestward from Camp 1 to the mouth of Disenchantment bay bears evidence of being the upheaved side of a fault of quite recent origin. The steep inclination and shattered condition of the rocks along this line are evidently due to the crushing which accompanied the displacement. In the wild gorge above our first camp, a small glacier was found descending to within 500 feet of the sea-level, and giving rise to a wild, roaring stream of milky water. Efforts to reach the glacier were frustrated by the density of the dripping vegetation and by the clouds that obscured the mountains. A canoe trip was made to a rocky islet between Knight island and the mainland toward the north. The islet, like the rocks in the adjacent mountain range, is composed of sandstone, greatly shattered and seamed, and nearly vertical in attitude. Its surface was densely carpeted with grass and brilliant flowers. Many sea birds had their homes there. From its summit a fine view was obtained of the cloud-capped mountains toward the northeast, of the dark forest covering Knight island, and of the broad plateau toward the southeast. Some of the most charming effects in the scenery of the forest-clad and mist-covered shores of Alaska are due to the wreaths of vapor ascending from the deep forests during the interval in which the warm sunlight shines through the clouds; and on the day of our visit to the islet, the forests, when not concealed by mist, sent up smoke-like vapor wreaths of many fantastic shapes to mingle with the clouds in which the higher mountains disappeared.
