Travels in Alaska

"After eleven years of study and exploration in the Sierra Nevada of California and the mountain-ranges of the Great Basin, studying in particular their glaciers, forests, and wild life, above all their ancient glaciers and the influence they exerted in sculpturing the rocks over which they passed with tremendous pressure, making new landscapes, scenery, and beauty which so mysteriously influence every human being, and to some extent all life, I was anxious to gain some knowledge of the regions to the northward, about Puget Sound and Alaska."
