With the planning of the Federal Interstate Highway System and the stepped up program for improvement of State roads in Iowa, has come an ever increasing need for the development of new sources of road building materials. Some areas of the State have abundant resources of good limestone and sands and gravels suitable for construction of highways, whereas other sections of the State are relatively poor in good material. One of these previously poorer areas, through which one section of the proposed four lane interstate road passes, is dealt with in this paper.
