David Woon made a recent visit to the Eagle Harbor Lighthouse campus for several different views, showing off both sides of the building. Then he takes us right inside for a look at the old Fresnel Lens that used to show boaters the way through thick fog and stormy weather.

The last photo was snapped by Paul Fifer, who zoomed in closer and click the shutter just at the right time to capture the glow of the red portion of the rotating light. Is it common for lighthouses to feature a duo light, with the red and white light?

Thank You for these great pictures of one of my favorite Lighthouses!

GREAT shots!

AWESOME! I totally love this lighthouse!! I'm a huge lighthouse fan anyway, but there's just something about this one!!

Thanks and have a great day!

What a neat lighthouse! Just love where this located. Wonderful shots, thank you.

Good pics. Those Fresnel lenses with their prism effects are awesome.

The Lighthouses of Michigan and Maine look very much alike.

While sailing aboard the CRISPIN OGLEBAY we would go at times from Silver Bay, Mn to Chicago and while out in Lake Superior we would view this light for what seemed like a whole day. The ship would be traveling at 10mph so for hours it was always abeam to us and a good feeling for me being originally from the area.

That light will shine 29 miles out onto the lake.

"Although sailors today have complex instruments to guide their ships, they can still depend on the signals of the Bay’s lighthouses for basic information about their location. Each lighthouse flashes a pattern of light that is different from that of every other lighthouse. Navigation charts describe this pattern of light so that sailors can know their exact location.

There are a lot of different kinds of signals, for instance a light that shines all the time is called a fixed light. All lighthouse lights are white, red, or green, or a combination of these three colors. After sighting and timing the flashers of a lighthouse, the ships captain refers to a light list. From this list, the captain can determine which lighthouse is in view and can then figure the ships location from looking on a chart." - Lighthouse signals from Wordpress

Thanks for that explanation, Len.
