The oddity, explained
Why is Ark unusual?
Ark appears here because the approved source classifies it as maritime. The source describes it as Ark was a ketch built in 1873 and lost on 09/11/1881. Broke rudder head in south easterly gale. Stern post started and the vessel sank. Heritage Atlas treats that specific classification-and-description combination as the oddity; the score is a comparative discovery signal, not proof of mystery or the supernatural.
Evidence and further exploration
The coordinate, category and description remain tied to the cited source. Comparative oddness helps discovery; it does not add facts that the source does not provide.
