Captain Cook judged it to be about fifty feet high, and half a mile in circuit.

It was flat at the top, and its sides rose in a perpendicular direction, against which the sea broke to a great height.

The weather continuing to be hazy, the captain, on account of the ice islands, was obliged to proceed with the utmost caution.

Six of them were passed on the 12th, some of which were nearly two miles in circuit, and sixty feet high; nevertheless, such were the force and height of the waves, that the sea broke quite over them.

Hence was exhibited a view, that for a few moments was pleasing to the eye; but the pleasure was soon swallowed up in the horror which seized upon the mind, from the prospect of danger.
