Ravine

Inside a ravine in Upper Missouri River Breaks National Monument, Montana, United States.

A ravine is a landform narrower than a canyon and is often the product of streamcutting erosion.^[1] Ravines are typically classified as larger in scale than gullies, although smaller than valleys.^[1]

Definition

A ravine is generally a fluvial slope landform of relatively steep (cross-sectional) sides, on the order of twenty to seventy percent in gradient. Ravines may or may not have active streams flowing along the downslope channel which originally formed them; moreover, often they are characterized by intermittent streams, since their geographic scale may not be sufficiently large to support a perennial watercourse.^[2]
