Summary[edit]

Description

Two Harbors, MN is a small port along the North Shore of Lake Superior. The city is built along two harbors -- Burlington Bay and the larger Agate Bay. Agate Bay has a large breakwall that stretches out into the lake and behind that breakwall is a pair of gigantic loading docks that are used to load bulk freighters with taconite pellets. These massive ships then travel to other parts of the Great Lakes and deliver the taconite pellets to plants that turn them into steel.

Today, this port sees only a three or four of these large bulk freighters each week. During the early 1900s, it would see dozens of them each week. In order to make it easier to locate and navigate into the harbor, the USLHS built a lighthouse on the shore of the lake to mark the location of the harbor. They also included a fog signal.

This lighthouse is now the oldest continuously operating lighthouse in Minnesota. It is operated by the Lake County Historical Society as a museum and the light itself is still maintained as an active aid to navigation.

The original lens for the light was a fourth order fresnel lens. In 1969 that lens was removed and replaced with a pair of 24" aerobeacons. The grounds include the lighthouse, the attached keepers quarters, the assistant keeper's house, the fog signal building, and the skiff house.

This photo was taken standing in the watch room, the room directly below the lantern room which contains the aerobeacons. These are DBC-224 beacons that are rotated electrically to give the light the characteristic flash pattern.
