Workers removed the overburden of soil to expose the limestone before quarrying could begin. They loaded the debris into side dump-cars, which donkey engines pulled along rails toward the lake. En route, workers spread the dirt beside the tracks. When the soil built up to a point that side-dumping became impossible, workers moved the track south a few feet and began the cycle again. This very straight hill, approximately 1/8 mile long, was built from this overburden, and workers stood beside a donkey engine used to haul soil from the quarry.
