Lighthouses Automated
During the 1920s and 1930s, the U.S. Coast Guard increased safety on the Great Lakes.
It installed newly designed light buoys, automated lighthouse lamps, launched the first
icebreaking Coast Guard cutter and published "Notices to Mariners." By the 1930s,
many fog signals were powered by electricity and activated by remote control. By 1940,
nearly all lighthouses had electricity.
 The
museum's Fresnel Third Order
lighthouse lens was removed from the Lansing Shoal Station when the station was fitted
with a solar light in 1985. The Lansing Shoal Station marks the entry into the Straits of
Mackinac for ships coming from Lake Michigan. It was built in 1928.
Also in the gallery is the maritime case with information about Great Lakes travel and
shipping. During the 1930s, you could cruise in luxurious passenger vessels. Create your
own Great Lakes fantasy trip .
