SITE GEOLOGY AND GROUNDWATER <br /> The surficial geology consists primarily of terraces-areas that were once channels <br /> or floodplains -left behind by the Mississippi River in the Pleistocene.These occur <br /> above current floodplain areas but below nearby moraine or outwash areas.The <br /> property itself is located within the Mississippi Sand Plain (Figure 4). <br /> These terraces are principally sand,gravel,and some finer materials, especially <br /> along the Mississippi and its smaller tributaries (Hobbs and Goebel 1982). In and <br /> around Bailey Point,the depth from surface to bedrock is 200 feet or less (Olsen and <br /> Mossier 1982). <br /> Throughout the site,the depth to groundwater ranges from 15 to 45 feet,which is <br /> quite shallow. Groundwater generally flows to the south across the site,roughly in <br /> the direction of the confluence of the Elk and Mississippi Rivers. <br /> Friends of the Mississippi River Bailey Point Nature Preserve NRMP <br /> 16 <br />
