About this map

Semiahmoo Bay defines the southern portion of this borderland survey, where the marine waters meet the international boundary. This specific quadrangle covers a stretch of the northernmost United States, tracing the line of Canada United States of America as it bisects the bay. The landscape is primarily defined by its coastal orientation and the rectilinear patterns of the Public Land Survey System, specifically t41n r1w, which organizes the local road network and property divisions near the boundary. The map illustrates a contemporary view of the region's shoreline and drainage patterns, documenting the transition from maritime environment to the structured settlement patterns characteristic of the Pacific Northwest border.
