There is in eastern Iowa one short journey which shows a more interesting variety of land forms in small space than can be seen almost anywhere else. It shows too, in a typical way, the different surface aspects of areas belonging respectively to the driftless area and to the plains of Kansan and Iowan drift. For these reasons the journey referred to should become famous, and might well become a standard in certain particulars, among students of Pleistocene deposits and topographic forms. The journey is over the Illinois Central railroad; it begins at Dubuque, and it may end at Dyersville. The whole distance does not exceed thirty miles.
