What the evidence supports
IOMHER records Neptune as having grounded on 20 February 1817. IOMHER classifies the reported casualty position as “Approximate”. The map represents that reported position as an uncertainty area, not a surveyed wreck footprint. It is not evidence that visible remains survive at the centre point.
