Point Bonita Lighthouse for kids
The Lighthouse and the Fog Cannon. A true story near Sausalito, CA, told for kids 3-12.

Read along
Way out at the tippy-tip of these cliffs is the Point Bonita Lighthouse. To get there, you walk through a tunnel dug into the rock by hand, and then across a tiny wobbly bridge. It looks like a baby Golden Gate Bridge! But here's the funny part.
Long ago, when the fog got super thick, ships couldn't even see the light. So the lighthouse got a fog cannon! A soldier had to fire the cannon every half hour, all night long, to warn the ships. Boom!
One soldier fired it for three whole days and nights, with hardly any sleep, and he got sooo tired. Later they got a big clanging bell, and after that, a giant foghorn. Much easier!
