About this map

Fidalgo Island is defined by a landscape of industrial infrastructure and coastal settlements at the end of the 1970s. Large oil refinery complexes dominate the northern neck of the island near Fidalgo Bay, while the Burlington Northern railroad lines connect the industrial waterfront to the interior. The map illustrates the interface between public lands and private development, featuring the extensive Deception Pass State Park and Reception Island State Park alongside residential areas like Similk Beach and Yokeko Point.

To the east, the Swinomish Indian Reservation boundary is clearly delineated, separated from Fidalgo by the Swinomish Channel. Local history is preserved through markers such as Fern Hill Cem, the Grange Hall near Summit Park, and a trio of educational institutions including Mt Erie Sch, St Marys Sch, and Fidalgo Sch. The bathymetric data provides a detailed view of the surrounding sounds, including Similk Bay and Skagit Bay, showing the underwater contours that shape this island network.
