Pennekamp Archaeological Investigations

Archaeological Investigations

Indiana University conducts periodical assessments of the 18th Century Mock Spanish Shipwreck to ensure the integrity of the site and sustain its maintenance. IU’s most recent assessment of the site indicates that the present artifacts are in good condition. The submerged cannons have maintained their structural integrity, though many of them are missing the zinc anodes that were attached to them prior to installation on the site. What remains are the retaining straps and bolts meant to support the anodes, which do show signs of deterioration. Many have loosened their grip on the cannons, allowing for potential damage. Previous IU visits succeeded in filing down the empty straps and bolts, but more anodes have been lost since then. The anchor remains in good condition, with only the anchor eye showing deterioration on the left side, compromising the anchor ring which was previously attached. The land-based cannons remain uncompromised, though the epoxy coating which protects them from environmental exposure shows mild erosion and pitting.

Anchor Orthomosaic

There is 18th Century anchor located near the cannons, as part of the mock shipwreck site in John Penneekamp Coral Reef State Park in Key Largo, Florida. The anchor orthomosaic and 3D model are missing the right fluke, but reprocessing could yield a more complete rendering.  See the 3D modeling page for an interactive 3D model of the anchor.
