It is a canyon cut through the mountains by an ancient river. It is the only sea-level gap in the coastal mountain range for hundreds of miles. Why does the fog come through the Golden Gate? The water vapor cools and condenses into tiny water droplets – fog. Fog is formed when the moist air over the ocean is cooled by cold water currents along Northern California’s coast. Warm air is less dense and exerts less pressure than cooler air, allowing the cooler ocean air to push its way in through the Golden Gate. Another foghorn at midspan between the towers sounds a pair of high-pitched notes.įog is most common in the summer, when the air over the interior land heats up more than over the ocean. The south tower foghorn sounds a deep, loud note for 2 seconds, then it repeats in 18 seconds. Then, wait about 2 seconds to hear the sound waves reach your ears through the air, traveling a little faster than a jet airliner.

There was no time for the Lifesavers to get to the stricken ship. The lives of 128 passengers were lost when the ship quickly filled with water and sank. ![]() The worst maritime disaster in these waters happened in 1901, when the steamer City of Rio de Janeiro was caught up in the fog and struck rocks somewhere on the San Francisco side of the strait. The lifesaving crew lived there, in a house with a tower above it-a perfect perch from which to observe the entire Strait. To your left, on the hill are white houses. The station was equipped with a boathouse with rail launch way, surfboat, lifeboat, a line cannon breeches buoy, and a beach cart. Their motto: You have to go out, but you don't have to come back. This one was built in 1911, and manned by lifesavers, primarily rugged Scandinavian sailors, whose purpose was to rescue shipwrecked souls. Stations like this were built on the West Coast beginning in 1874. ![]() Fog remains a constant danger.ĭirectly below you, on the beach, there are the remains of the original Lifesaving Service boathouse.

It is a wonder of the world, and San Francisco's own golden gateway. Even today, few suspension bridges are as long, and none more spectacular. The middle span between the 44,000-ton towers stretches 4,200 feet. Upon opening in May 1937, the Golden Gate Bridge was the longest suspension bridge in the world. For four years, from January 1933 to April 1937, bridge construction proceeded. In the 1930s while the Golden Gate Bridge was under construction, people from San Francisco stood along the shore including where you are now, watching as mechanical looms spun the giant cables in midair. An unmistakable profile and the world's most familiar image of California. Two slender cables support a six-lane roadway held aloft by two soaring towers. The city rose like a phoenix from the ashes of 1906, and energetically, marched into the modern age, hosting two World's Fairs and ultimately built an unmistakable symbol of San Francisco's pride of place, the magnificent Golden Gate Bridge-75 years young this year!
