Beyond Mary Island and Point Retreat
More Lights Along Alaska’s Coast
Explore the lighthouses and light stations that helped guide vessels through Alaska’s island passages, remote straits, and busy approaches.
Beacons for a Vast and Rugged Shore
Alaska’s coastline stretches through island chains, narrow channels, and exposed waters where fog, darkness, and shifting weather can make landfall difficult. Lighthouses and smaller navigational lights gave mariners recognizable points of reference as they approached harbors and threaded coastal passages.
From Southeast Alaska to the Gulf of Alaska, these signals supported fishing boats, passenger vessels, and commercial traffic traveling routes that remain vital today.
Many stations began as staffed outposts, with keepers maintaining lamps, sounding fog signals, and watching over isolated stretches of coast. Automation changed how the lights operated, but not the importance of the locations they marked.
Explore the structures below to see where each stands, how its station developed, and why its light mattered to navigation in Alaskan waters.
Explore Alaska’s Other Light Stations
Cape St. Elias Light
Kayak Island · Gulf of Alaska
Established in 1916 at the southern tip of Kayak Island, this station marked a prominent headland on Gulf of Alaska routes. Explore its history and coastal setting.
Eldred Rock Light
Lynn Canal · Southeast Alaska
First lit in 1906, Eldred Rock helped vessels navigate Lynn Canal’s challenging waters on the route toward Skagway and Haines. Learn about the station and its enduring landmark.
Cape Hinchinbrook Light
Hinchinbrook Island · Prince William Sound
Established in 1910, this light marked the seaward approach to Prince William Sound, guiding vessels near a key entrance to the region’s ports. Read its story.
Mary Island Light
Southeast Alaska Light Station
Client
Location: Mary Island, near the entrance to Revillagigedo Channel
Date
Established: 1903
My Role
Category: Historic lighthouse and navigation aid
Project Overview
Set on Mary Island south of Ketchikan, this light marked a vital approach through the island-studded waters of Southeast Alaska. Established in 1903, it helped mariners identify the entrance to Revillagigedo Channel and navigate toward Ketchikan in an era when coastal shipping connected remote communities. Its enduring story reflects the importance of dependable lights along Alaska’s Inside Passage.
Point Retreat: A Guide at Lynn Canal’s Entrance
On the northern tip of Admiralty Island, Point Retreat stands beside the approach to Lynn Canal, the long waterway leading toward Juneau, Haines, and Skagway. A light was established here in 1904 as vessel traffic grew along this important Southeast Alaska route. Later changes to the station reflected advances in lighting and automation, but its purpose remained the same: helping mariners recognize a pivotal point and maintain their bearings in challenging coastal waters. Explore the dedicated Point Retreat page for more of its history and role in navigation today.
Milestones in Alaska’s Coastal Lights
From early coastal markers to modern automated aids, Alaska’s lights have helped mariners travel between ports, passages, and remote communities. These milestones offer a starting point for exploring the structures featured across Alaska Lighthouses.
'80s
Early Navigation Aids Take Shape
In the 1880s, growing marine traffic in Alaska’s coastal waters increased the need for dependable markers and lights along busy approaches.
'03
Mary Island Light Is Established
Established in 1903 near Revillagigedo Channel, Mary Island Light helped guide vessels approaching Ketchikan and the Inside Passage.
'04
Point Retreat Joins the Route
Point Retreat’s light began marking the entrance to Lynn Canal in 1904, supporting travel toward communities farther north.
'60s
Automation Changes the Watch
Across the mid-20th century, automated equipment gradually reduced the need for resident keepers while navigation lights continued to serve coastal traffic.
How Alaska’s Lights Serve the Coast
Hazard Warnings
Lights help vessels identify rocky shores, reefs, and other dangers in Alaska’s challenging waters.
Passage Markers
Beacons mark approaches to channels and straits, helping mariners navigate important coastal routes.
Harbor Approaches
Lights near harbors give crews recognizable reference points as they approach sheltered waters.
Community Connections
By aiding vessels that carry people and supplies, coastal lights have supported communities linked by sea.
Historic Watchpoints
Each structure reflects the navigational needs of its location and the changing history of travel along the coast.
Alaskan Landmarks
From Mary Island Light to Point Retreat, these structures remain distinctive markers in Alaska’s maritime landscape.
