Lake Superior National Estuarine Research Reserve, Research reserve on Lake Superior in Wisconsin, US.
Lake Superior National Estuarine Research Reserve is a protected area where the St. Louis River meets the western tip of Lake Superior. The site combines wetlands, forests, beaches, dunes, and marshes across a large landscape.
The reserve was established in 2010 to protect and study coastal environments along Lake Superior. It became part of a national system dedicated to understanding the transitional zones where rivers meet large bodies of water.
The estuary contains numerous Native American cultural sites and preserves historical locations related to the region's lumbering and shipping industries.
Access is mainly on foot or by boat, with different trails and waterways matching the varied habitats. The best time to visit is spring through fall, when weather is stable and wildlife is easier to spot.
Wisconsin Point holds the world's largest freshwater mouth sand bar, a rare geological formation that draws researchers. This sand bar creates unusual conditions for plant and animal life, making it a location of major scientific interest.
