| Comment |
Nonsorted steps are only found on slopes, commonly ranging from 5? to 15?; their downslope border forms a low riser fronting a tread whose slope is less than the general slope. Nonsorted steps are assumed to be derived from nonsorted nets or hummocks or nonsorted polygons, rather than to develop independently.
