- noun A sharp, isolated eminence which rises from the sea-bottom.
Sorry, no etymologies found.
We see the bases of the precipices hollowed and worn, with all their rents and crevices widened into caves; and mark, at a picturesque angle of the rock, what must have been once an insulated sea-stack, some thirty or forty feet in height, standing up from amid the rank grass, as at one time it stood up from amid the waves.
For it so chances that one of the main incidents of the story bears reference to an insulated sea-stack; and it is connected altogether, though I cannot fix its special locality, with this part of the coast.
a sea-stack, skirted with algæ, the breakers on this shore must have dashed every tide through the narrow opening of the cavern, and scooped out by handfuls the decomposing trap within.
