The whole of Sand Point is made up of sand deposited by the currents of Lake Superior as the water moves through Munising Bay. Over hundreds of years, the sand deposits were colonized by different vegetation such as beach grasses, pine trees, and blueberry bushes. The shoreline continues to change today as new sand accumulates in places and existing beach erodes away. The process doesn’t stop in winter as Lake ice pushes and carves the frozen shoreline. The photos collected from this station show how the sand bars and beaches of the area shift over time, as well as how the levels of Lake Superior fluctuate from year to year.
