The St. George Reef Light is an inactive lighthouse built on North West Seal Rock, six miles (10 km) off the coast of northern California near Crescent City.

[4] The loss of prominent people on the steamer was an impetus to the light's approval; nonetheless, it took until 1892 to complete due to the changing availability of federal construction funds.

[4] Duty at St. George Reef was among the most difficult of any station, due to its remote location and being surrounded by unpredictable, treacherous seas.

Several people died during its construction and operation, dozens resigned or sought transfer, and a few even suffered mental breakdowns.

[4] The light station was replaced by a "floating lighthouse" buoy and decommissioned in 1975, and its 8-foot (2.4 m)-high first-order Fresnel lens was removed in 1983 for display at the Del Norte County Historical Museum in Crescent City.

[10] The lighthouse was listed in the National Register of Historic Places, reference number 93001373, on December 9, 1993,[3] and was commemorated on a USPS postage stamp in 2007.

Probably the most violent storm experienced at this lighthouse was that of 1923, when huge seas from a northwesterly direction broke on the platform of the tower, 70 feet (21 m) above water, with such violence as to tear the donkey-engine house from its foundation.

There were ever-present hazards to be encountered in the manning of St. George Reef Lighthouse, located on storm-lashed Northwest Seal Rock.

A 1,000,000 candela lamp, marker radio beacon, and a two-tone diaphone fog signal was her armament against disaster to shipping.
