North Pier Light

The light tower on the north pierhead at the Duluth’s ship canal was established in 1910, despite the keystone above the doorway dated 1909. It contains a 5th order Fresnel Lens that displayed a white beacon for decades until Oc- tober 7th, 1999, when a red acrylic lens housing was put in place. It was always meant to be red to correspond with the ”red light returning” rule of thumb. The white and black conical steel tower, the shape referred to as a frustum, is 37 feet high. The beacon is 46 feet above the surface of the lake. The Duluth ship canal was dug in 1871 and today, due to the completion of the Saint Lawrence Seaway in the 1950s, welcomes marine traffic from all over the world. Concrete replaced the original wooden piers in 1898 and they stood unchanged until their reno- vation and reinforcement in the 1980s.
