On November 15, the Marion Natural History Museum’s community group enjoyed a presentation on the geology of cranberry bogs with USDA soil scientist Maggie Payne. We heard about the glaciers that covered our area and left glacial moraines or hills in some areas of our state, as well as glacial outwash in our area. These outwash areas of sand and gravel can be extremely deep. Chunks of ice melting on the landscape turned into kettle ponds, which filled with groundwater and eventually plants.
