During last summer it was my good fortune to visit the three largest snowfields in Norway, namely, Folgefond, at the head of Hardangerfjord, in Southern Norway, whose area is 108 square miles; the Jostedalsfond, two degrees to the northward, and beyond Sognefjord, whose area is 580 square miles, and the largest snowfield in Europe; and the Svartisen, of nearly equal area, extending from just inside the Arctic Circle for 44 miles to the northward. All of these snowfields send down glaciers to within from 50 to 1200 feet of the sea.
