    An example is Seljalandsfoss in southern Iceland, where isostatic (dynamic) uplift has occurred as a result of both construction and deglaciation. Static rejuvenation may also occur, in rare instances, when a downstream knickpoint erodes its way upstream to a lake which establishes base level for its tributaries.

    The canyon itself can act as a connection between the east and the west by providing corridors of appropriate habitat along its length. [145] The canyon can also be a genetic barrier to some species, like the tassel-eared squirrel. [145] The aspect, or direction a slope faces, also plays a major role in adding diversity to the Grand Canyon.

    Brady Canyon is a cliff-forming gray limestone with some chert. Wood Ranch is a slope-forming pale red and gray siltstone and dolomitic sandstone. An unconformity marks the top of this formation. One of the highest, and therefore youngest, formations seen in the Grand Canyon area is the Kaibab Limestone (see 6d in figure 1).
