Near Lakeside and Marblehead Ohio on Lake Erie is a large quarry for mining limestone. They mine inland move material on what appears to be a several thousand foot long conveyor onto waiting freighters or barges that take this stuff all over the Great Lakes. We were on the water just passing through watching them load up a barge and tug. Close enough to smell and taste the dust in the air though. The color and repeating patterns of the structure of the dock and the conveyor were too much to pass up for a quick shot as we came around.
