Traverse City's Sleeping Bear Dunes air quality benefits from the exceptional Lake Michigan coastal position with the famous sand dunes rising 110 metres above the lake, with Lake Michigan's consistent and powerful lake winds providing outstanding maritime ventilation. Vehicle traffic on M-22 contributes modest local sources, while the extraordinary lake exposure and the dune ecosystem's unique open geometry generally maintain Sleeping Bear Dunes among Michigan's most reliably ventilated major natural attractions throughout most of the year.
