The Interior Plateau Ecoregion, which was never glaciated, is an area with Quaternary loess, colluvium and alluvium underlain with Mississippian and Pennsylvanian shale, sandstone, and limestone (Woods et al.
This feature may attest to a lengthy stagnant ice field on insular heights of glacial origin (Karukapp & Raukas 1994; Lundqvist & Wohlfarth 2001), resultant slope- and thermokarst processes, and burial of organic sediments under colluvium.
Stability analyses carried out assuming the potential slip surface and shear strength of the colluvium mass overlying the sliding surface gave high factors of safety.
