Forest Preserve

In 1916, the Forest Preserve District of Cook County began acquiring land to create a natural retreat for Chicagoans in that booming metropolitan region. Since district officials acquired many properties along county streams, water pollution soon interfered with their mission of creating an urban wilderness for recreational pleasure. To address the problem, in 1931, county leaders appointed the Clean Streams Advisory Committee that collaborated with forest preserve staff members to pressure polluters to clean-up their operations and to persuade enforcement agencies to prosecute ongoing offenders. They also lobbied the Public Works Administration to earmark New Deal funding for sewage treatment in Cook County. Their efforts suggest that early activism against water pollution in American cities emerged not only from efforts to ensure clean drinking water, but also struggles to protect nature. The interwar campaign to clean forest preserve streams anticipated the goals of the federal Clean Water Act (1972) to make all American waterways fishable and swimmable. The movement also preceded the burst of anti-pollution activism that historians have documented in U.S. suburbs after WWII and laid the groundwork for postwar efforts to mitigate water pollution in Cook County.

Nipissing Phase

Study of past lake-level change and isostasy in the upper Great Lakes has demonstrated the need to reconstruct relative lake-level history at each outlet during the Nipissing phase of ancestral Lakes Huron, Michigan, and Superior. Although elevation and age data exist for the Port Huron/Sarnia and Sault outlets of Lake Huron and Lake Superior, respectively, no paleohydrograph has been created for southern Lake Michigan near the Chicago outlet. The Wentworth Woods area of the Cook County Forest Preserve, Illinois, contains more than 30 beach ridges that formed during the rise and fall from the peak elevation of the Nipissing phase. These relict shorelines were vibracored to recover basal foreshore sediments that can be used as a proxy for lake-level elevation at the time of individual shoreline formation. In addition, sand samples from soil pits and vibracores were collected for optically stimulated luminescence age determinations. This report addresses the sedimentological data used to determine the elevation of the conjoined upper Great Lakes (Lake Nipissing) when each beach ridge formed. The age data will be presented in future reports.
