1970 Map of Port Austin West

USGS Topo · Published 1973

About this map

The northern tip of Michigan's Thumb is captured here in 1970, where the waters of Lake Huron meet Saginaw Bay. This coastal landscape is defined by its recreation and Cold War infrastructure, notably the Port Austin Air Force Station situated near the eastern edge. Along the shoreline, the treacherous nature of the lake bottom is revealed by the extensive Flat Rock Point Reef and Hat Point Reef, which extend significantly from the coast. The map provides a detailed view of the Port Crescent State Park and the historic Port Crescent area, where the Pinnebog R winds toward the bay. Interior roads like Knoblock Road and Ahearn Road service the farmland behind the coastal bluffs, while local history is preserved at the Port Crescent Cem.
