NOAA's Wisconsin Shipwreck Coast National Marine Sanctuary

NOAA's Wisconsin Shipwreck Coast National Marine Sanctuary WSCNMS provides stewardship for our national maritime heritage in Lake Michigan

Designated in 2021, Wisconsin Shipwreck Coast National Marine Sanctuary provides stewardship for our nation's maritime heritage in Lake Michigan. Co-managed by NOAA and the state of Wisconsin, the sanctuary expands on the state's 30-year management of these historic sites, bringing new opportunities for research, resource protection, and education. In partnership with local communities, the sanctuary provides a national stage for promoting recreation and heritage tourism. The 36 historic shipwreck sites within the sanctuary represent vessels that played a central role in building the nation between the 1830s and 1930s. Twenty-seven are listed on the National Register of Historic Places and research suggests that another 60 shipwrecks may yet to be discovered.

Hello and welcome back to another ! Today we are featuring the canal schooner WALTER B. ALLEN!

WALTER B. ALLEN was built in 1866 by shipwright, H.C. Pierson in Ogdensburg, New York. WALTER B. ALLEN was built as an "extreme" sailing canaller, constructed to fit within the tight confines of the second generation Welland Canal locks. These “extreme” sailing canallers had very specific dimensions that were only slightly smaller than the size of the locks at this time. Additionally, these vessels were built with a flat bottom, a sharp turn of the bilge, and a plumb bow. WALTER B. ALLEN had many other unique canaller features as well, like folding davits and catheads, and a bowsprit that could be raised and lowered to traverse the canal locks.

H.C. Pierson actually built two sailing canallers which now lie on the bottom of the Great Lakes: WALTER B. ALLEN (1866) and E.B. ALLEN (1864). E.B. ALLEN has many of the same unique features as WALTER B. ALLEN, though the vessel was slightly shorter and less boxy, demonstrating the difference between the earlier "moderate" canaller and the later "extreme" canaller designs. Today, E.B. ALLEN lies within the NOAA Thunder Bay National Marine Sanctuary.

WALTER B. ALLEN spent much of its career carrying grain and lumber eastward, and returning with coal to fuel the growing cities of the western Great Lakes region. WALTER B. ALLEN served as a workhorse of this important east-west trade until April 1880, when the vessel ultimately was lost beneath Lake Michigan - twice.

On April 10, 1880, while sailing past South Manitou Island from Chicago, a gale swept WALTER B. ALLEN ashore. During the grounding, the vessel lost its mainsail as well as its anchor. Three days later, the tug CAROLINE WILLIAMS, of Manistee, Michigan assisted in pulling WALTER B. ALLEN off the island and towed it across Lake Michigan for repairs. The tug arrived with a large steam pump to be used to pump water out of the vessel. The pump, installed on the vessel’s deck, was successfully able to pump out the vessel enough to refloat it. Filled with a waterlogged cargo of grain, WALTER B. ALLEN was bound for Manitowoc to unload and receive repairs, however, Manitowoc did not have the capacity for the wet grain, so CAROLINE WILLAMS continued south toward Milwaukee with WALTER B. ALLEN in tow.

On April 16, 1880, as the two vessels were sailing south toward Sheboygan, the wind began to increase, and waves quickly began crashing over WALTER B. ALLEN's bulwarks. The vessel began to fill with water and eventually the steam pump could no longer keep up. Soon after, the canaller slowly sank while the crew was rescued by CAROLINE WILLIAMS.

Today, WALTER B. ALLEN sits upright in 165 feet of water, southeast of Whistling Straights Golf Course. The hull of WALTER B. ALLEN remains almost entirely intact, with only its cargo hatches, and cabin structure missing. Both masts remain on site, though they no longer remain upright. The site was documented by Wisconsin Historical Society maritime archaeologists and volunteers in 2010, and it was listed on the National Register of Historic Places in 2011. In August 2024, the site was outfit with a sanctuary mooring buoy for easier dive access.

You saw our posts about our educators workshop last month, and we're here to tell you it was AMAZING!

Thanks to our partners at MATE ROV Competition, the first MATE Academy held in Wisconsin Shipwreck Coast National Marine Sanctuary was an overwhelming success. We had 12 educators from all over Wisconsin (and beyond!) learn how to build their own ROVs at Visit Sheboygan!

Now these educators can work with their students and teach them all about ROVs and underwater robotics, helping excite the next generation of underwater explorers!

It's that time of year again... 🍂🍁🌊

The weather is getting colder and its almost time for the sanctuary shipwreck mooring buoys to be hauled in for the winter.

At the end of each dive season our surface buoys are pulled out of the water before strong winter storms and ice move in. This time out of the water helps us keep the buoys in good shape and complete any necessary updates or repairs before they are redeployed in the spring.

Although the surface buoys are removed each fall, each of these sites have a yellow subsurface buoy at 40ft that stays in the water year round! So for you cold-water, year-round diving enthusiasts, you'll still be able to locate and dive these sites, even in the winter! To learn more about our buoy locations, visit: https://sanctuaries.noaa.gov/wisconsin/science/

Buoy removals will begin in mid-October! We will keep you updated as we go! After their winter respite, the buoys will be back out on the lake by early June for next year's dive season!

Hello everyone and welcome back to another ! Today we are featuring the schooner LOOKOUT!

LOOKOUT was built as a schooner in 1855 in Buffalo, New York, with a clipper style hull, built for speed. Clipper-type hulls were commonly used in ocean going vessels and not often seen in the Great Lakes. They had a sharper deadrise and a much narrower hull than other Great Lakes vessels. Throughout its career, LOOKOUT carried grain, coal and lumber to various ports throughout the region.

LOOKOUT had a 45-year sailing career; remarkably long for a vessel of the era. On April 29, 1897, LOOKOUT was caught in a gale while rounding Twin Rivers Point (Rawley Point) and ran aground only 200 yards off shore in the “quicksand” of the point, with its bow facing shore. At 5AM the following morning, a life service station patrol discovered the stranded vessel and the local lifesaving crew began preparing their surfboat.

As the storm and surf continued to rage, LOOKOUT's captain ordered the crew to the yawl boat and row for shore. Fortunately, the entire ship’s crew made it safely, meeting the lifesaving crew on the beach. The next day, the vessel's deck was completely awash, and the hull was completely stuck in the sand. One of the anchors, some anchor chain, and part of the rigging was saved, along with navigation instruments from the cabin, but the vessel itself could not be pulled out of the sand, and it was declared a total wreck.

Today, LOOKOUT remains largely buried, only a few hundred yards off shore of Point Beach State Forest, in 10 feet of water. The vessel's bow, a section of the vessel's starboard side hull up to the deck shelf, the vessel's lower hull, and centerboard remain intact, however, moving sand continues to cover large sections of the wreckage, preserving it.

The site was discovered in 2015 by ultralight pilot Suzze Johnson, recorded in July 2015 by Wisconsin Historical Society maritime archaeologists and volunteers, and nominated to the National Register of Historic Places in 2017. In 2024, maritime archaeologists and researchers returned to LOOKOUT to gather updated imagery, site documentation, and water quality data. The site can be seen from the water's surface on a calm day; perfect for paddlers to visit! A marker buoy seasonally marks the site’s location (June – October).

Hello and welcome back to another ! This week we are featuring the lakeshoring schooner NORTHERNER!!

NORTHERNER was built in 1850 in Clayton, New York at the shipyard of John Oades. The vessel began its career sailing on the eastern Great Lakes carrying general merchandise, entering ports that were unreachable by larger schooners. Measuring just over 80 feet in length with a shallow draft, NORTHERNER could enter small, unimproved ports easily to carry goods to towns along the shoreline. Lakeshoring schooners were used heavily throughout the Great Lakes during this time period, as many of the ports in the region were shallow and unimproved, meaning larger vessels could not frequent them. These small schooners were able to fill this void, transporting bulk cargo and merchandise to and from hinterland ports. Even as many ports expanded, lakeshoring schooners continued to be used well into the second half of the 19th century.

By the early 1860s, NORTHERNER moved to Lake Michigan and began in the lumber trade, transporting cargo from small Lake Michigan lumber ports to the larger cities of Milwaukee and Chicago. On November 28, 1868, while loading cordwood at Amsterdam Pier (near today’s Amsterdam Park), NORTHERNER hit the lake bottom heavily. Unbeknownst to the crew, the hull had sustained considerable damage, and shortly after setting sail, a large leak was discovered in the hold. NORTHERNER was able to make it to Port Washington to offload a portion of its cargo to lighten the vessel before being taken under tow to Milwaukee for repairs. While on its way, NORTHERNER continued to leak, eventually capsizing while off Port Ulao. The crew was picked up by the tow vessel while NORTHERNER quickly settled to the lake bottom. Despite the relatively shallow depth of the wreck, no attempts to salvage the vessel or its cargo were ever made.

Today, NORTHERNER sits in 130 feet of water, south of Port Washington. The vessel remains almost completely intact, with only its cabin structure, hatch covers, and mainmast missing. The vessel’s foremast has become unstepped from the keelson and rests over the starboard side bow railing. The vessel’s remaining cargo of cordwood can still be seen inside the vessel’s hull. One particularly unique part of NORTHERNER is its beautifully carved, scroll figurehead, which can still be seen just beneath the vessel’s bowsprit.

In 2009, the site was recorded by the Maritime Preservation and Archaeology Program at the Wisconsin Historical Society and the vessel was listed on the National Register of Historic Places in 2010. In 2021, divers and archaeologists from NOAA returned to the site to gather imagery for a 3D photogrammetry model, and in 2024, the site was outfit with a sanctuary mooring buoy for divers to safely and responsibly access the site!

Have you been wanting to learn more about our recent NOAA Ocean Exploration project from earlier this summer? You're in luck!

Back in July, researchers from Wisconsin Shipwreck Coast National Marine Sanctuary, Hibbard Inshore, and NOAA Great Lakes Environmental Research Laboratory returned to Wisconsin Shipwreck Coast to test new techniques for exploring deep-water shipwrecks, using a hybrid autonomous underwater vehicle/remotely operated vehicle. Using a combination of photography, laser scanners, and multibeam sonar data, the team returned to SENATOR to complete documentation of the wreck site and surrounding lake bottom nearly 450 feet below the water’s surface.
