Description
The wreck identified as “VESSLTERMS UNKNOWN” is a submerged object located in Lake Superior near LATDEC 46.598811, LONDEC -90.877081. This site presents a significant navigation hazard due to the wreck’s extremely shallow depth of 3 feet at LWD. This makes it perilous for vessels, particularly smaller recreational crafts or those operating near shore.
Historical Survey Summary
•1941 Survey: Initial recognition of the wreck as a navigational hazard. Scaled on Chart 14974 (NAD 1902) at 1:15,000, identifying its hazardous potential.
•1984–1985 Surveys: Precise surveys using updated hydrographic tools determined its accurate location and depth. Recommended retaining the wreck on navigation charts due to its hazardous nature.
The surveys revealed that the wreck lies almost at surface level during low water periods, making it a critical hazard for surface navigation.
Significance and Risk Assessment
Navigation Hazard
The submerged wreck poses a direct danger to navigation due to:
•Shallow Depth: At 3 feet depth, the site is barely submerged, particularly during low water.
•Visibility: Depending on water conditions, the wreck may not be visible from the surface.
•Traffic Area: Its location in Lake Superior may coincide with active boating and shipping lanes, increasing the potential for accidents.
Current Recommendations
•Chart Retention: Hydrographers strongly recommend maintaining the wreck’s charted status to ensure mariner safety.
•Advisory for Mariners: Mariners should exercise caution when navigating near these coordinates, avoiding the area to mitigate collision risks.
Potential for Further Study
The lack of identification opens avenues for further investigation:
1.Diving Exploration: Given its shallow location, the wreck could be studied to ascertain its origin and historical context.
2.Hydrographic Updates: Modern sonar surveys could further refine its structure and possible movement due to sedimentation or lake currents.

Conclusion
The wreck known as “VESSLTERMS UNKNOWN” stands as a critical navigation hazard in Lake Superior. While its identity remains a mystery, its precise location and depth emphasize the importance of keeping it charted to safeguard maritime activities. Further exploration could offer insights into its historical significance while ensuring continued navigational safety in the region.
