| Comment |
Sorted steps are only found on slopes ranging from 5? to 15?; their downslope border forms a low riser fronting a tread whose slope is less than the general slope. Sorted steps are presumed to be derived either from sorted circles or from sorted polygons, rather than to develop independently. Some sorted steps clearly form an intermediate stage between sorted polygons and sorted stripes.
