2023 Map of Point Houghton

USGS Topo · Published 2023

About this map

Isle Royale Wilderness dominates this remote archipelago landscape, where dramatic volcanic ridges define the island's interior. Parallel geological formations, including Minong Ridge and Greenstone Ridge, create a corrugated topography that directs the flow of the Little Siskiwit River and shelters inland waters like Lake Desor. Along the southern coast, the map documents the narrow peninsula ending at Point Houghton, separating the open expanse of Lake Superior from the protected waters of Siskiwit Bay. This survey captures the isolated character of the island’s southern reaches, from the maritime hazards of Butterfield Shoal to the seasonal shelters at Fishermans Home Cove. The network of footpaths, such as the Ishpeming Trl and Minong Ridge Trl, highlights the transition from early resource extraction to a landscape managed for conservation and wilderness recreation.
