As one portion of the country after another has had its glacial geology cleared up in recent years by the enthusiastic research which later theories have inspired, doubtless more than one glacialist has turned his eyes toward Missouri, which exhibits a wider area of extramorainic drift than is found in any other state, and shows northern drift at the remotest point from its original source, unless, possibly, Kansas takes the palm in these respects. It is, therefore, with satisfaction that I attempt a brief exposition of the facts which I have been able to discover in about three months’ field work in connection with the Missouri Geological Survey. I regret that I could not bring the work nearer completion, but as I shall not, at least for some time, be able to carry it farther, it seems best to offer this report of progress for consideration, comparison and criticism. . . .
