Sea Stack

Coastal and Reef Features

A sea stack, or simply a stack, is a steep and often vertical column of rock standing in the sea near a coast, formed by wave erosion. Hydraulic action, the force of water crashing against a headland, widens cracks in the rock until part of the headland collapses, leaving a free standing pillar or even a small island; a stack can also form when a natural arch collapses under its own weight. Continued erosion eventually causes the stack itself to collapse, leaving behind a low stump. Sea stacks provide important nesting sites for seabirds and many are popular destinations for rock climbing.
