In Northern Alberta this isnow known as the Edmonton series and it probably iscontinued south as the St. Mary River beds.This last division furnishes coal over a large area reachingfrom Manitoba to near the mountains. In Manitoba theserocks occupy the summit of Turtle Mountain in the south.In Assiniboia, or the new Province Saskatchewan, they under-lie portions of the Cypress Hills and cap Wood Mountain andthe Coteau, and occupy a shallow syncline eastward throughwhich the valley of the Souris is cut and from which muchof the lignite consumed in the eastern section is obtained.

It owes its exposure herealtogether to the uplift of the Rocky Mountains and is foundto the west of the outer break of the range. This outerbreak has been of such dimensions that the uplifted beds onthe west exposed the lower rocks as low down in the series asthe Cambrian, and these latter rocks are found thrust up overthose of the middle Cretaceous to the east of the fault. Atthe gap of the Ghost River, Mr. McConnell observed an over-thrust of over two miles, and estimates the total there to benearly seven. A rough diagram of the section as observed at the BowRiv
