About a hundred miles further south, but still in Alberta, we have the well-known Crow's Nest Mountain, a lone peak, which consists of these same Algonkian limestones resting on a Cretaceous valley "in a nearly horizontal attitude," as G.M. Dawson says, which "in its structure and general appearance much resembles Chief Mountain,"[50] another detached peak some fifty miles further south, just across the boundary line in Montana. Chief Mountain has been well described by Bailey Willis,[51] who estimates that the Cretaceous beds underneath this mountain must be 3,500 feet thick; while the so-called "thrust plane is essentially _parallel to the bedding_" of the upper series.[52] "This apparently is true not only of the segments of thrust surface beneath eastern Flattop, Yellow, and Chief Mountain, but also of the more deeply buried portions which appear to dip with the Algonkian strata into the syncline. While observation is not complete, it may be assumed on a basis of fact that thrust surfaces and bedding are nearly parallel over extensive areas."[53] [Footnote 49: Report, 1886, Part D, p. 84.] [Footnote 50: Report, 1885, Part B, p. 67.] [Footnote 51: _Bull. Geol. Soc._, Vol. 13, pp. 305-352.] [Footnote 52: _Id_., p. 336.] [Footnote 53: _Id_., p. 336.] Quite recently this region has been studied by Marius R. Campbell of the Washington Survey Staff (Bulletin 600), while the part in Alberta has been studied by Rollin T. Chamberlin of Chicago. Much of the vast area involved is not yet well explored; but over it all, so far as it has been fully examined, the same lithological and stratigraphical structures reappear with the persistence of a repeating decimal. And were it not for the exigencies of the theory of Successive Ages, this whole region of some five or six thousand square miles would be considered as only an ordinary example, on a rather large scale, of undisturbed horizontal stratification cut up by erosion into mountains of denudation, with of course occasional instances of minor local disturbances here and there, as would be expected over an area of this extent. Richards and Mansfield in a recent paper describe the "Bannock Overthrust," some 270 miles long, in Utah, Idaho, and Wyoming. The Carnegie Research recently reported a similar phenomenon about 500 miles long in northern China. But it would be tiresome to follow these conditions around the world. We have plenty of examples, and we have them described by the foremost of living geologists. What we need to do now is to adopt a true scientific attitude of mind, a mind freed from the hypnotizing influence of the current theories, in order correctly to interpret the facts as we already have them.
