===Transition forms and shoulders===

Depending on the [[topography]], the [[rock type]]s, and the [[climate]], a variety of transitional forms between V-, U- and plain{{clarify|date=January 2021}} valleys can form. The floor or bottom of these valleys can be broad or narrow, but all valleys have a shoulder. The broader a mountain valley, the lower its shoulders are located in most cases. An important exception is canyons where the shoulder almost is near the top of the valley's slope. In the Alps – e.g. the [[Tyrol (state)|Tyrolean]] [[Inn River|Inn]] valley – the shoulders are quite low (100–200 meters above the bottom). Many villages are located here (esp. on the sunny side) because the climate is very mild: even in winter when the valley's floor is filled with fog, these villages are in [[sunlight|sunshine]].

In some stress-tectonic regions of the [[Rocky Mountains]] or the Alps (e.g. [[Salzburg]]), the [[side valley]]s are parallel to each other, and are [[hanging valleys|hanging]]. Smaller streams flow into rivers as deep canyons or [[waterfall]]s.
