The oddity, explained
Why is Perce Rock unusual?
Perce Rock appears here because the approved source classifies it as odd boundaries. The source describes it as rock formation off the coast of Quebec, Canada. 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.
