2017 Map of Point Houghton

About this map

Isle Royale National Park dominates this remote archipelago landscape, where the southern reaches of the island meet the cold waters of Lake Superior. The topography is defined by parallel ridges like Houghton Ridge, which separate the interior lakes and wetlands from the rugged shoreline. Extensive water bodies such as Lake Desor and Mud Lake drain through the Little Siskiwit River toward the protected waters of Siskiwit Bay. Small, tucked-away coastal features like Little Boat Harbor and Fishermans Home Cove hint at the island's maritime history and the seasonal shelters used by those navigating the Houghton Point Passage. From Checker Point to Butterfield Point, the map details a complex interface of rocky points and shoals that have long challenged Lake Superior mariners.
