Valley - Transition Forms and Valley Shoulders

Transition Forms and Valley Shoulders

Depending on the topography, the rock types and the climate, a lot of transitional forms between V-, U- and plain valleys exist. Their bottoms can be broad or narrow, but characteristic is also the type of valley shoulder. The broader a mountain valley, the lower its shoulders are located in most cases. An important exception are canyons where the shoulder almost is near the top of the valley's slope. In the Alps – e.g. the Tyrolean Inn valley – the shoulders are quite low (100–200 meters above the bottom). Many villages are located here (esp. at the sunny side) because the climate is very mild: even in winter when the valley's floor is completely filled with fog, these villages are in sunshine.

In some stress-tectonic regions of the Rockies or the Alps (e.g. Salzburg) the side valleys are parallel to each other, and additionally they are hanging. The brooks flow into the river in form of deep canyons or waterfalls. Usually this fact is the result of a violent erosion of the former valley shoulders. A special genesis we find also at arêtes and glacial cirques, at every Scottish glen, or a northern fjord.

Famous quotes containing the words transition, forms, valley and/or shoulders:

    The most remarkable aspect of the transition we are living through is not so much the passage from want to affluence as the passage from labor to leisure.... Leisure contains the future, it is the new horizon.... The prospect then is one of unremitting labor to bequeath to future generations a chance of founding a society of leisure that will overcome the demands and compulsions of productive labor so that time may be devoted to creative activities or simply to pleasure and happiness.
    Henri Lefebvre (b. 1901)

    This is the Scroll of Thoth. Herein are set down the magic words by which Isis raised Osiris from the dead. Oh! Amon-Ra—Oh! God of Gods—Death is but the doorway to new life—We live today-we shall live again—In many forms shall we return-Oh, mighty one.
    John L. Balderston (1899–1954)

    Jugful of milk! It was yours years ago
    when I lived in the valley of my bones,
    bones dumb in the swamp. Little playthings.
    Anne Sexton (1928–1974)

    ... with her shoulders as bare as a building,
    with her thin foot and her thin toes,
    with an old red hook in her mouth,
    the mouth that kept bleeding
    into the terrible fields of her soul . . .
    Anne Sexton (1928–1974)
