Terracette
From Wikipedia, the free encyclopedia
In geomorphology, a terracette is a type of landform, a ridge on a hillside formed when saturated soil particles expand, then contract as they dry, causing them to move slowly downhill.
It may also be described as a small, irregular step-like formation on steep hillslopes, especially on those used for pasture which are formed by creep or erosion of surface soils exacerbated by the trampling of livestock such as sheep or cattle. Synonyms (not preferred) are: catstep, sheep or cattle track.
