2023 Map of Roche Harbor OE S

About this map

Haro Strait and the Salish Sea dominate this maritime-focused survey, centered on the international boundary between the United States of America and Canada in San Juan County. The map is defined by the sharp angles of the international border line as it cuts through the open waters of the archipelago. Aside from a small cluster of unnamed islands and coastal points on the western edge, the sheet provides a meticulous view of the nautical boundary corridor during the early 2020s. The survey accurately documents the meeting point of deep-water channels, serving as a contemporary record of the aquatic topography and political geography where Washington State meets British Columbia.
