The Big Bay Point Lighthouse stands on a rocky point halfway between Marquette and the Keweenaw Portage Entry.
Situated on the edge of a sand bluff on the west bank of the Eagle river, has a focal plane of 61 feet.
The red brick Eagle Harbor Light Station sits on the rocky entrance to the harbor and is a working lighthouse as it guides mariners across the northern edge of the Keweenaw Peninsula. The original lighthouse, built in 1851, was replaced in 1871. The octagonal brick light tower is ten feet in diameter, with walls 12 inches thick and it supports a 10-sided cast iron lantern. The Lighthouse was manned by a head keeper and two assistant keepers.
