2019 Map of Feldtmann Ridge

About this map

Isle Royale National Park dominates the landscape of this Lake Superior wilderness, where tectonic forces and glaciation have left a series of parallel upland features. The prominent Feldtmann Ridge and adjacent Coyote Ridge run southwest-to-northeast, defining the island's interior topography and providing the route for the Feldtmann Ridge Trail. These basaltic ridges overlook the lower drainages where the Big Siskiwit River flows toward the coast. Along the shoreline, the map identifies specific maritime and coastal landmarks such as Long Point, Attwood Beach, and the offshore McCormick Reef. Further inland, Lake Halloran sits tucked behind the coastal heights, illustrating the diverse interior hydrology of the island. This survey provides a clear view of the wilderness trail systems and geological formations that characterize the southwestern portion of the archipelago in the early 21st century.
