In the lowerbeds of the series it is thought that the fold will be lessmarked, and in the angle contained between the fold and thefault, there is probably a sharp anticline. Northward fromhere to the Cascade Mountain, the Cretaceous is overlappedby the limestone from the west, but a series of flexures in thecoal-bearing measures are found in the Canmore mines, which. SKETCHES OF THE CRETACEOUS PIvATKAU BETWEEN THE BOW AND THEKANANASKIS RIVERS. The upper one is looking across the valley of the Kananaskis southward, and shows thecoal-bearing beds dipping beneath the limestone. The foreground in each shows thelimestone abutting against the Cretaceous, forming a fold in the latter by thepressure. are probably continued along in front of Rundle Mountain,and seem to indicate that the direction of pressure was not atright angles to the fault, but more from the west. As thesliding of the limestone was upward along the fault, a seriesof waves in the coal seams might have been expected run-ning parallel to the fault and not far from horizontal. Thosefound, however, have a pitch downward toward the south. Apossible explanation may be deduced from the fact that thefault line in the vicinity of Anthracite is deflected to thenorth and then gradually dies out or is changed into a foldwith less displacement. This gives
