Exhaustion of many of the gravel supplies in Hamilton County, and difficulty in locating others, has led recently to more careful consideration of limestone rock deposits as sources of road and concrete materials. It has long been known that Mississippian limestones and sandstones are found exposed along Boone River near Webster City, such being mentioned by MacBride,1 in 1909. Miller and Norton,2 and later, Norton3 described deep well sections at Webster City, referring the upper part of them to the Mississippian. With the proportion of limestone found in the surface exposures, and reported at greater depth in the well sections, it appeared possible that a large quantity of stone might be quarried. A reconnaissance of the territory was therefore made, and a site chosen for core drilling.
