1954 Map of Roche Harbor

About this map

San Juan Island and Henry Island define the northwest corner of the archipelago, separated by the narrow currents of Mosquito Pass. This survey illustrates the area's transition from an industrial resource hub to a protected historical landscape, notably featuring the English Campsite (1859) at Garrison Bay, a remnant of the mid-19th-century boundary dispute between the United States and Canada. The economic history of the islands is etched into the terrain at Roche Harbor, where several Quarries and a Quarry indicate the area's once-thriving lime industry.
