The Chester A. Congdon was a bulk steel freighter named after the lawyer and capitalist of the same name. It was launched in 1907 and sank on November 6, 1918 in Lake Superior near Isle Royale. The wreckage remains at the bottom of the lake, and in 1984 was placed on the National Register of Historic Places.

History

The Chester A. Congdon (Official Number 204526) was constructed in 1907 by the Chicago Ship Building Co. of South Chicago Illinois under the name Salt Lake City for Holmes Steamship Company of Cleveland, Ohio. The ship was 552 feet long, having a 56-foot beam and 26 foot draft, with a gross tonnage of 6530 tons and a net tonnage of 4843 tons. The ship was powered by a 1,765HP triple expansion steam engine with two Scotch boilers.

In 1911, the Salt Lake City was sold to the Acme Transit Company of Ohio. In early 1912, the ship was purchased by the Continental Steamship Company and renamed the Chester A. Congdon, after the Duluth, Minnesota lawyer and industrialist Chester Adgate Congdon. The ship's record was largely uneventful, but it was grounded twice, once in 1912 and once in 1915.

Wreck

Wreck of the Congdon

On November 6, 1918, the Congdon departed from Thunder Bay, Ontario with 380,000 bushels of wheat aboard. Later that day, the Congdon ran aground in the fog at Canoe Rocks, near Isle Royale, which were subsequently renamed Congdon Shoal. The captain immediately dispatched a boat to nearby Passage Island to request assistance and sent a second boat back to Thunder Bay.

All crew members were rescued, and an attempt to salvage the cargo resulted in only about 20% being saved. A storm on November 8 broke the freighter in two, and it sank. Although another salvage operation was mounted later in 1918, nothing more was recovered from the wreck. The Congdon is significant in that her wreck was the first on Lake Superior to be valued at over a million dollars, and was the largest loss up to that time in both dollar value and net tonnage.

The Chester A. Congdon today

The wreckage of the Congdon sits in 50–200 feet of water, with the bow section on the south side of the reef and the stern on the north side. The stern section is in considerably deeper water than the bow, and represents a more technical dive. The bow section of the Congdon sank upright, and the pilot house on the bow is still intact, a relatively rare occurrence. Many of the ship's furnishings were salvaged while the ship was still on the reef. Approximately 160 dives were made to the Congdon in 2009 out of 1062 dives made to wrecks in the Isle Royale National Park.
