As I stood on the steep-sloped ridge, the Atrevida and Lucia glaciers, their surfaces covered from side to side with angular masses of sandstone and shale, lay at my feet; while farther up the valley the débris on the surface of the ice disappeared, and all above was a winter landscape. The brown, desolate débris-fields on the glacier at my feet extended far southward, and covered the expanded ice-foot in which the glacier terminates. Most curious of all was the fact that the moraines on the lower border of the glacier were concealed from view by a dense covering of vegetation, and in places were clothed with forests of spruce trees. To the southward, beyond the end of the Lucia glacier, and separated from it by a torrent-swept bowlder-bed, lay a vast {93} plateau of ice which stretched toward the south and west farther than the eye could reach. This is the Malaspina glacier, shown on plate 8. Its borders, like the expanded extremity of the Lucia glacier, are covered with débris, on the outer margins of which dense vegetation has taken root. All the central portion of the ice-sheet is clear of moraines, and shone in the sunlight like a vast snow-field. The heights formerly reached by the nearer glaciers were plainly marked along the mountain sides by well-defined terraces, sloping with the present drainage. When the Lucia glacier was at its flood the ridge on which I stood was only 200 or 300 feet above its surface; now it approaches 1,000 feet. Turning toward the southeast, I could look down upon the waters of Yakutat bay, with its thousands of floating icebergs, and could distinguish the white breakers as they rolled in on Ocean cape. Beyond Yakutat stretches a forest-covered plateau between the mountains and the sea, and the eye could range far over the mountains bordering this plateau on the northeast. In the distance, fully a hundred miles away, stood Mount Fairweather, its position rendered conspicuous by a bank of shining clouds floating serenely above its cold summit. The mountains directly east of Yakutat bay rise to a general height of about 8,000 feet, but are without especially prominent peaks. In a general way they form a rugged plateau, which has been dissected in various channels to depth of 2,000 or 3,000 feet. Nearly all of the plateau, including mountains and valleys, is covered with snow-fields and glaciers; but none of the ice-streams, so far as can be seen from a distance, descend below an elevation of about 4,000 or 5,000 feet. This region is as yet untraversed; and when the explorer enters it, it is quite possible that deep drainage lines will be found through which glaciers may descend nearly or quite to sea-level.
