Except they be trained geologists few Iowans there are who would ordinarily think of looking for mountains in the smooth, illimitable prairies such as characterize this state of ours. Yet the evidences are many and plain, not only of the effects of mountain-making activities, but of the mountain roots themselves traversing quite across our domains. Amongst the latter are, indeed, indubitable traces of at least one mountain range that once reared its walls as loftily, as imposingly, and as majestically as do to-clay the Rockies above the Colorado plain.
