SHIPWRECK REPORT: Unknown Submerged Wreck (Record #2376)

IDENTIFICATION & SITE INFORMATION

•Record Number: 2376

•Type: Submerged Shipwreck (Unknown vessel)

•Location:

•Latitude: 46.758877

•Longitude: -88.458742

•Lake: Superior

•Depth: 6 feet (1.8 meters) at least depth (pole sounding)

•Condition: Dangerous submerged wreck

VESSEL TYPE DESCRIPTION

This wreck, identified during hydrographic surveys, remains an unknown submerged vessel. While its origin, construction, and historical significance are unclear, the wreck lies partially obscured within shoreline ruins. The site’s difficult Visibility and proximity to other debris suggest it may have been a victim of severe weather, grounding, or intentional scuttling.

HISTORY

•1936 Survey: Initially charted as a visible wreck during a revisory survey of Lake Superior.

•1975 Revisory Survey: The wreck’s condition was updated to “dangerous sunken wreck,” reflecting changes in its profile or potential hazard to navigation.

•1981 Survey (CES14971): The wreck’s position was verified using R/AZ control, confirming its coordinates as Lat 46-45-32.2N, Long 88-27-31W. The least depth was determined to be 6 feet by pole sounding.

The wreck lies in shallow water near shoreline ruins, making it challenging to identify specific details or confirm its historical background. The low Visibility in the water (approximately 10 feet or 3 meters) further complicates site assessment.

FINAL DISPOSITION

The wreck is considered dangerous and remains charted as such. Its shallow depth and location in a pocket of shoreline ruins increase the risks for navigation, emphasizing the need for caution in the area.

SIGNIFICANCE OF THE SITE

The unknown wreck provides a mysterious glimpse into the maritime history of Lake Superior. Its identification and documentation are critical to understanding the vessel’s purpose, origin, and role in regional history. Its classification as a hazardous site underscores the importance of accurate charting and continued monitoring to ensure safe navigation in the area.

FUTURE EXPLORATION & PRESERVATION

Efforts to identify the wreck could involve:

1.Advanced Imaging Technology: Use of sonar and underwater photogrammetry to obtain detailed imagery of the wreck.

2.Archival Research: Investigating historical records of lost vessels near the coordinates during the early 20th century.

3.Diving Expeditions: Professional divers could assess the condition and recover any identifiable artifacts or markings.

Preservation of the site should focus on protecting its structural integrity and ensuring it remains documented as a navigational hazard.

NOTMARs & ADVISORIES

This wreck is charted as a “dangerous submerged wreck” on nautical maps. Mariners should exercise caution when navigating near Lat 46-45-32.2N, Long 88-27-31W, especially given the shallow depth and potential for submerged debris.
