Probably the upper portion of the gorge was widened by a glacier, and the narrow slit at the bottom represents post-Glacial cutting. The main valley, from the side of which the photograph was taken, is clearly of glacial origin, and the side valley must have borne a hanging relation to that of the master stream.
We have shown that the recent physical history of the region is legibly recorded in glacial sculpture and moraines, in orogenic movements, in valley-cutting and terracing, in lake expansions, and
