Our measurements in open-tube piezometers failed to document saturated conditions within the colluvial body of the landslide, although we did find water under artesian pressure in the limestone layers in the underlying bedrock. The pressures varied on an annual cycle, producing minimum values during the fall and maximum values in late spring. Most of the failure surfaces are well above the contact between bedrock and colluvium and, thus, subsurface water pressure in the bedrock is not a major control on the reactivated movement of these thick landslides.
