Description :
The AA. have sampled 144 pedons of 16 catenas with different slope aspects and curvatures in a 70 km2 area in Wisconsin. Half of all the pedons had a red clay subsoil. The thickness of the red clay ranged from 4 cm to 60 cm with an average thickness of 25 cm. The red clay was found in every part of the landscape except the valley bottoms : it was present in soils on summits, shoulders, backslopes, and footslopes. The red clay is only found over dolostone, but not present on all dolostone ridges. It was concluded that there is large variation in the Terra Rossa soilscapes of Wisconsin and this variation can only partly be explained by topography.
