Lincoln Rock and Lincoln Island are small islets in Clarence Strait, part of the Abraham Islands just off the west coast of Etolin Island, about 63 miles (102 km) northwest of Ketchikan and 31 miles (50 km) southwest of Wrangell, Alaska. They were named in 1886 by Lieutenant Commander Albert S. Snow of the US Navy for Abraham Lincoln, the 16th president of the United States. Another Lincoln Island is located in Southeast Alaska, in Lynn Canal near Juneau.

A lighthouse was contracted for construction on Lincoln Rock in March 1902, but owing to bad weather and substandard materials, the work was not completed until late 1903. The station was plagued by foul weather, and part of the landing platform was carried away by heavy seas. Further damage was sustained in November 1909 and April 1910 during severe storms. After establishing a temporary light, the keepers evacuated Lincoln Rock in December 1910.

In 1911, funds were appropriated to build a manned fog-signal station on the larger, grass-covered Lincoln Island, about 1,300 feet (400 m) east of Lincoln Rock. Construction was completed on October 10, 1911, and in 1944 a skeletal light tower was added. The station was decommissioned and demolished in 1968; today only the building foundations remain. A modern light on a steel skeleton tower is currently active on Lincoln Rock. Read more here and here. Explore more of Lincoln Rock and Clarence Strait here:
