The Powder River is a large intermontaine basin that formed during the Laramide orogeny. The basin was initially occupied by a large, mudfloored lake, which is represented by the Lebo Shale Member of the Fort Union Formation seen in Fig. Infilling of the lake set the stage for accumulation of the exceptional coal seams of the Tongue River ...
