"Shadow Over Lime Point" ~ The shadow of the Golden Gate Bridge towers over the old 1833 fog signal building on Lime Point. Keepers used two 12-inch steam whistles to warn vessels of the rocky spur. The whistles were powered by steam created by coal-fired boilers until converting to oil-fired boilers in 1902. The station became automated in 1962 and is still in operation today.
