Abstract

It is a fact almost too well known to state here that the most important single problem in earth-study with which we have to deal in Iowa is that of exact mapping of the different rocky formations. Unlike the cases in the majority of states, the work in this state is vastly simplified by the fact that there has been apparently little orogenic disturbance in the region, and the geological terranes of fundamental consequence mainly belong to a single geologic era. Calling the problem somewhat simple does not by any means signify that the labor of discrimination and tracing of the formation boundaries is easy, or that it is not highly varied.
