The rock exposed in quarries southwest of Garner, Iowa, has been in question as to its stratigraphic position, having been correlated with both Middle and Upper Devonian formations with no supporting evidence. Stratigraphic control was established by comparing lithologies present in the Cedar Valley, Shell Rock, and Lime Creek formations in exposures and noting the changes that occur in the subsurface through a detailed study of well cuttings. Lithologic and paleontologic evidence supports a Lime Creek correlation.
