1982 Map of Spider Island

About this map

Newport State Park dominates the rugged shoreline of the Door Peninsula in this early 1980s coastal study, preserving a significant stretch of woodland and sandy coastline within the town of Liberty Grove. The map details the transition from land to the deep waters of Lake Michigan, highlighting the dangerous shoals and small islands that define this maritime environment. Just offshore, Spider Island and the Gravel Island National Wildlife Refuge provide protected habitats for local bird populations. Inlets such as Europe Bay and Newport Bay break the rocky coast, while a small inland Gravel Pit indicates the local extraction of materials for road building or construction. The bathymetric data reveals a complex underwater topography, including Outer Shoal and Four Foot Shoal, which historically challenged navigation along this stretch of the Great Lakes.
