Some anomalous structural features in the Great Plains area of Alberta have been known for a long time, but in recent years they have come into considerable prominence because of the prospect of commercial oil pools being associated with them. The study of one of the most conspicuous of these supposed uplifts, together with the result of wells recently drilled in the vicinity, indicate fairly conclusively that there has been no uplifting of the formations in the area, and that the abnormally steep dips and local folds and faults are the result of the thrust of the great ice-sheet which moved southward over this area in Pleistocene time.
The object of this paper is to demonstrate, if possible, two points, namely:
(1) That the intense deformation of the beds observed at Mud Buttes and similar localities is entirely superficial and without deep-seated significance and in no way connected genetically . . .
