Patos Island Lighthouse, Historical lighthouse in San Juan County, United States.
The wooden lighthouse stands 8 meters tall on Alden Point, featuring Greek Revival architecture with a fourth-order Fresnel lens guiding vessels through Boundary Pass.
Congress allocated $12,000 for construction in 1891, and by November 1893, the lighthouse commenced operations with both a Daboll trumpet lighting system and fog signal.
The Keepers of the Patos Light organization maintains exhibits about maritime heritage and preserves the environmental quality of the 207-acre island.
Tours of the lighthouse occur during summer weekends when volunteer docents are present, indicated by a clapboard sign on Active Cove beach.
The first keeper's assistant, Edward Durgan, raised an upside-down flag to signal for help when seven of his thirteen children contracted smallpox on the isolated island.
