17 Friends of the Mississippi River Camp Cozy Park NRMP <br />Site Geology and Groundwater <br />The surficial geology consists primarily of terraces – areas that were once the river channel or <br />floodplains carved by the torrential flow of the Glacial River Warren in the Pleistocene epoch. <br />These occur above current floodplain areas but below nearby meander channel areas. The <br />property itself is located within the Mississippi Sand Plain (Figure 4). <br /> <br />These terraces are principally sand, gravel, and some finer materials, especially along the <br />Mississippi and its smaller tributaries (Hobbs and Goebel 1982). In and around Camp Cozy, the <br />depth from surface to bedrock is roughly 200 feet (Olsen and Mossler 1982). <br /> <br />Throughout the site, the depth to groundwater is consistently 0-10 feet, which is quite shallow. <br />Groundwater flows to the south/southeast across the site, generally in the direction of the Elk <br />River. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />
