Red Hills (Kansas)

This undulating terrain of red-tinted sediments, a product of the underlying geology, does not fit the conventional description of the Great Plains landscape of Kansas.

[3] The shallow playas were intermittently flooded then dried leaving a mixture of lacustrine sediments and gypsum evaporites.

The red color derives from the oxidation of iron contained within the deposits.

The dissolution of underlying gypsum beds has led to the formation of sinkholes which are common features within the Red Hills region.
