1959 Map of Mc Neil Island

About this map

Mc Neil Island (Federal Penitentiary) dominates the upper half of this coastal survey, showing the complex of reservoirs, filtration plants, and pumping stations that supported the institution. This mid-century view documents the internal road network of the prison, including Butterworth Reservoir and Eden Creek Reservoir, alongside the shoreline features of Still Harbor and Gertrude Island. Southward across Balch Passage lies Anderson Island, defined by a more dispersed settlement pattern including Villa Beach and Johnson Landing. The Steilacoom Ferry route provides a vital link across Puget Sound, while the mainland edge to the southeast shows the early footprint of the Fort Lewis Military Reservation. Notable landmarks like the McDermott Point Lighthouse (Abandoned) and family-named points like Mahnckes Point offer specific data points for local maritime and land-use history.
