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.
