These flash floods probably happened more than once. The canyon is a classic V-shaped valley, indicative of river-type erosion rather than glaciation. Today the canyon is still being eroded by the Yellowstone River. The colors in the canyon are also a result of hydrothermal alteration.
A gulch is a deep V-shaped valley formed by erosion. It may contain a small stream or dry creek bed and is usually larger in size than a gully. [1] Sudden intense rainfall upstream may produce flash floods in the bed of the gulch. Witches Gulch found in the Dells of the Wisconsin River. In eastern Canada, gulch refers to: [2]
In polar areas and at high altitudes, valleys may be eroded by glaciers; these typically have a U-shaped profile in cross-section, in contrast to river valleys, which tend to have a V-shaped profile. Other valleys may arise principally through tectonic processes such as rifting. All three processes can contribute to the development of a valley ...

Interlocking spurs at Ashes Hollow, tributary to the River Severn Interlocking spurs looking up Oxendale Beck, tributary to the River Brathay in Lake District, Cumbria. An interlocking spur, also known as an overlapping spur, is one of any number of projecting ridges that extend alternately from the opposite sides of the wall of a young, V-shaped valley down which a river with a winding course ...

[2] Vinstradal is a narrow V-shaped valley with steep valley sides and with a canyon in the valley's north end. The valley is covered by a mountain birch forest.
