From the Archives: Leland Iron Co. Dock Light

Little remains as evidence of the iron ore production. A lantern, chunks of pig iron abandoned, bricks from the furnace reused in local buildings, a few images, and iron ore slag that washes ashore along Leland's beaches. These few things that remain are important to remember and preserve and pass onto future generations.
