The sands were either eroded from glacial drift along the coast by wave activity or eroded from inland deposits and carried by rivers and streams. Only the hardest, smallest, and least soluble sand grains were moved. Waves and currents eventually moved these tiny rocks inland, creating beaches along the Great Lakes shoreline. |
