2023 Map of Lake Richie OE S

About this map

Isle Royale National Park dominates this maritime landscape along the northern edge of Lake Superior. The map focuses on a stretch of the shoreline where the Isle Royale Wilderness meets the cold waters of the great lake. Distinctive coastal features include the sheltered Vodrey Harbor and the shoreline at Little Greenstone Beach. Off the coast, the topography extends beneath the waves to define underwater landmarks such as Glenlyon Shoal, which presents a significant hazard for navigation in this portion of the archipelago. This 2023 survey by the U.S. Geological Survey captures the protected character of Isle Royale, showing the intersection of designated wilderness boundaries and the expansive aquatic reaches of the Keweenaw County shoreline.
