[note 1] The group is composed of seven small, sharp-peaked islets and rocks visible about 24 miles (39 km) in clear weather.

It is much larger than the others with three peaks, the tallest of which is about 360 feet (110 m);[1] a hole is seen through it from southwestward.

Three of the other islets lies east, about 1 mile (1.6 km) off its northern point.

The other three, about 75 feet (23 m) high, lies about 1⁄2 mile (0.80 km) off its southeast side.

For mariners, they are steep-to and may be passed on either side at a distance of 2 to 3 miles (3.2 to 4.8 km).
