Pilot Island Light
By Dave Wobser
Pilot Island is a small island, a couple of miles off the
tip of Door County Wisconsin, near the entrance to "Porte des Morts
Passage" or Death's Door.
Death's Door is most southern of the four the entrances
from Lake Michigan into the bay of Green Bay, between the many islands that
clutter the area. It is also the narrowest, but most convenient for vessels
traveling between Green Bay and lower Lake Michigan. The name was earned by
the number of shipwrecks that have occurred in the area over the years.
The first light in this corridor was built on nearby Plum
Island in 1848. The light proved to be ineffective and a new light was built
on Pilot Island 1858. At that time the island was known as Porte des Morts
Island, and the name was changed to Pilot Island in 1875.
The remaining 1858 tan brick, two-story, duplex keeper's
dwelling supports a short wooden tower and octagonal lantern room. The
original Fourth Order Fresnel lens has been replaced by a modern
solar-powered plastic light. The light is 48 feet above water level.
Due to the frequent fog in the passage, a fog signal bell
was established in 1862 and replaced by a foghorn in 1864. A steam-powered
fog siren was added in 1875 and in 1880 a separate building was built to
house a duplicate for siren.
In 1900 the fog siren were replaced with a 10" steam
whistle and a new building was built to house the new whistle. This building
also survives near the water edge.
What once was a small island covered with lush vegetation
has been almost completely denuded by the nesting (and subsequent manure) of
the protected cormorants.
Seeing this light is difficult, with a private boat being
the best option. The water around the island is shallow and rocky. During
the Door County Lighthouse Walk held each year in May, special excursions
are offered to view the island from a boat. The Walk is sponsored by the
Door County Maritime Museum & Lighthouse
In 2005, plans are underway to transfer ownership of the
island to the Door County Maritime Museum for preservation and restoration.
Historic Structures Get a Breath of Hope:
Ownership of Plum and Pilot islands finally transferred
11/7 - Door County, WI
- The long battle to save the Plum Island lighthouse took a critical step
forward when ownership of Plum and Pilot islands was transferred from the
U.S. Coast Guard to the U.S. Fish and Wildlife Service Oct. 17.
Plum Island, a 296-acre expanse located between Northport and Washington
Island, is home to a century-old lighthouse and a former Coast Guard
life-saving station abandoned by the service in 1991 when they moved
operations to Washington Island. In the years since the buildings have
fallen into sad disrepair.
“It’s very exciting news,” said Tim Sweet, President of Friends of Rock
Island State Park and a longtime advocate of saving the structures. Sweet
led the effort to restore Rock Island’s Pottawatomie lighthouse and would
like to do the same for the historic structures on Plum and Pilot Islands.
Sweet has worked diligently since 1999 to push the transfer process along as
it struggled through bureaucratic red tape.
The Fish and Wildlife service has wanted to take control of the abandoned
island for years to manage as part of the Green Bay National Wildlife
Refuge, which already includes Spider, Gravel and Hawk islands. The islands
are critical sanctuaries for migratory birds.
One of the hurdles in transferring the property was the contamination of
soil and water on the island caused by a decades-old incident in which an
above-ground diesel fuel tank burst and spilled fuel into the ground. The
contamination was finally addressed in 2004, mitigated at a cost of
Now Sweet and about 60 others have organized Friends of Plum and Pilot
Islands, which has begun planning and fundraising to preserve the
structures, labeled one of the ten most endangered historic properties in
the state in 2000 by the Wisconsin Trust for Historic Preservation.
Sweet said Pilot Island will be the greater challenge because the Fish and
Wildlife Service doesn’t want any public access on the island and it’s
further away. Efforts on Plum Island are expected to result in opportunities
for hiking, bird-watching, and possibly deer hunting down the road.
Two preservation architects recently visited the islands with the Friends
group to determine priorities and possibilities for the islands. Sweet
expects to get a report from them in the beginning of November.
Sweet said possibilities for restoration on Plum Island are more promising
because the roofs of the structures are in better condition.
“The pier there is one of the priorities we’ve identified,” he explained.
“Now we wait for the historic structures report to come back and then we can
approach different organizations who might provide funds and grants for the
The Fish and Wildlife Service is developing a management plan for the
islands, which would impact any restoration and visitation plans.
