Much new information concerning the underground geology of Iowa is being accumulated by the Iowa Geological Survey. Greater enthusiasm on the part of well contractors, municipalities, and the public in general has made it possible to obtain and study accurate sets of well cuttings from several widely distributed deep wells. The record and correlation of formations encountered in wells at Fort Dodge, Jefferson, Lenox, Ottumwa, Clinton, Dubuque, and Decorah are discussed in this paper. By the more detailed studies possible at this time, correlations of several key members have been made.
