Lime Kiln Light, San Juan Island

The Lime Kiln Light on the west coast of San Juan Island in Washington was established in 1914 when acetylene lights were placed on Lime Kiln Point, a name derived from the lime kilns built there in the 1860s. The light was updated five years later with a 38-foot (12 m) octagonal concrete tower rising from the fog signal building, and two light keeper's houses. A fourth-order Fresnel lens was added to the tower in 1919. The Coast Guard automated the light in 1962 and in 1998 the drum lens was replaced with a modern optic, flashing a white light once every 10 seconds. Sitting on the rocky shoreline at a height of 55 feet (17 m), the beacon is visible for 15 nautical miles (27 km) to guide ships through Haro Strait. Read more here and here.
