Description

This wreck, located in Lake Superior, lies at a depth of just 3 feet at LWD. It is considered a critical hazard to navigation, particularly for small crafts or during periods of low Visibility. Its shallow depth and proximity to active traffic zones make it especially perilous for surface navigation.

Historical Survey Details

1.1941 Survey:

•Identified as a navigational hazard.

•Included in Chart 14974 (NAD 1902) with scaling at 1:15,000.

•Depth unspecified.

2.1984–1985 Surveys:

•Leveraged advanced hydrographic tools.

•Pinpointed the location at decimal coordinates.

•Established the shallow depth of 3 feet at LWD.

•Highlighted the need to retain the wreck on charts due to its hazard potential.

Significance and Risks

•Navigation Hazard:

•The wreck’s minimal depth of 3 feet renders it dangerous to surface navigation, especially for smaller or poorly equipped vessels.

•Visibility: Likely submerged and undetectable during poor weather or high waves, exacerbating collision risks.

•Traffic Area: Its proximity to potentially active routes in Lake Superior adds to its risk profile.

Recommendations

1.Retention on Navigation Charts:

•Essential for mariner safety, ensuring the wreck’s location is visible to all using Chart 14974 or equivalent.

2.Mariner Advisories:

•Issue updated warnings to local and regional traffic about the site’s hazard potential.

Opportunities for Further Study

1.Diving Exploration:

•As a shallow site, the wreck could be accessible for direct exploration and documentation.

•Such efforts might uncover its origin and any historical significance.

2.Hydrographic Modernization:

•Contemporary sonar and mapping technologies can enhance understanding of the wreck’s structure and stability.

•Investigate whether lakebed sedimentation has influenced its current state.
