1 Birdbear well in Dunn County reveal carbonate-evaporate cycles consisting of alternating mudstone and dolomudstone beds, and an anhydrite capping carbonate mudstone to wackestone. The base of the upper unit is demarked by a 1.83 m--(6 ft) thick anhydrite cap that corresponds to the highest gamma ray spike above the Duperow Formation.

De acuerdo a la clasificacion de Dunham (1962) la caliza corresponde a un "wackestone" con una matriz homogenea, soportada por lodo, con una dolomitizacion secundaria de tipo sucroide, con bioclastos de gasteropodos, escasos braquiopodos y con abundantes microfracturas carbonatadas.
