The units above the Dewey Lake Red Beds consist of the Triassic Chinle Formation and the Santa Rosa Sandstone, small outliers of the Tertiary Ogallala Formation, and discontinuous bolson deposits of the Quaternary Gatuga Formation.

[John R Ege; Geological Survey (U.S.),]. Sinkholes are just one of many forms of ground collapse, or subsidence. Land subsidence is a gradual settling or sudden sinking of the Earth’s surface owing to subsurface movement of earth materials.

The principal causes of land subsidence are aquifer-system compaction, drainage of organic soils, underground mining, hydrocompaction, natural compaction, sinkholes, and thawing.

Evaporite salt beds are prone to dissolution by infiltration of undersaturated water, especially. Sinkholes. A sinkhole is a large dissolution cavity that is open to the Earth's surface.

Some sinkholes form when the roofs of caves collapse, others can form at the surface by dissolving the rock downward. Because we are here concerned with subsidence disasters and hazards we will concentrate on the formation of sinkholes by collapse.
