This image was taken at an active limestone aggregate quarry, which supplies crushed rock for area roads and other construction projects. We visit quarries like this, as well as road cut and river bank exposures, to study the bedrock and identify which formations are found at the bedrock surface. In many places in Iowa the bedrock is buried by glacial sediments and in those areas we rely on drilling logs from water wells in the area. Compiling a bedrock geologic map involves identifying the depth, thickness, and lateral extent of bedrock formations. This information can then be used to characterize bedrock aquifers and lead to better management of groundwater resources. Our maps can also be used by the aggregate industry to identify where future limestone resources are located, which may also lead to sustainable land use planning to avoid developing areas that may need to be quarried.
