Stacks solely happen the place rock is gentle sufficient to erode from a cliff, however on the identical time exhausting sufficient to assist a pillar.

Just like the so-called 12 Apostles — which really now quantity eight — the newly found underwater stacks have been as soon as half of a bigger limestone sea cliff relationship again 60,000 years.
