Summary
[edit]DescriptionDuluth North Pier Lighthouse - Fall 2011 (6403603999).jpg | This lighthouse is the last of the three lighthouses to be built in Duluth to make the Duluth ship canal. It is a cast iron tower over a skeletal frame and has a foundation of concrete. Originally, it was equipped with a 5th order fresnel lens and contained an electric lamp. The lens is still in place, but it has been surrounded with a red screen that changes the color of the light from a white light to a red light. |
