Alpena Cement Kiln Dust Project, Alpena Michigan

Click on Image for Interactive Satellite Photographs of the area.

In the early 1950's, cement kiln dust (CKD), a byproduct of the cement making process, was deposited onto the shores of Thunder Bay, in Alpena, MI. Over approximately four years, the pile grew to approximately the size it is today. Since then, natural processes have spread the pile out into the bay and down the shoreline. The current site covers approximately 80 acres, ranging in height from 30 feet to 68 feet above lake level. A portion of the pile now rises above lake level in areas that were once open water. In addition to the waste pile that is above water level, approximately 70 acres of CKD sediments now lie under the surface of Lake Huron. For more photographs of the site, click here.
