About this map

The maritime border between the United States and Canada defines this 2020 navigational perspective, cutting through the open waters of the northern Puget Sound region. The chart is dominated by the expanse of the Haro Strait, a critical waterway for local marine traffic and ecosystem health. To the south, the waters open into the broader Salish Sea, highlighting the international boundary that separates Washington state from British Columbia. While terrestrial features are absent, the map documents the modern legal and environmental division of these shared waters, emphasizing the deep-water channels that have shaped the Pacific Northwest's maritime history and international relations for generations.
