Each electric organ is made of 180-200 relatively large, fluid-filled hexagonal columns, which essentially act as batteries connected in parallel.

When the station opened, the walls were pale blue and the hexagonal columns on the platform dark blue.

Columnar Joints are joints that cut the formation vertically in (typically) hexagonal columns.

Wide basalt pillars, up to 7.5m (26ft) long, formed naturally into hexagonal columns.

Compared with other examples of columnar jointing, the Postpile has more hexagonal columns.

It is a hexagonal column with a red observation deck or gallery below the lantern.

The extensive crack networks that develop often produce hexagonal columns of lava.

The 10 painted hexagonal columns are each 9 feet tall and flared like trees or flowers.

The blue bend in the community's arms stands for the Roßbach, and the hexagonal columns refer to basalt quarrying's former importance.

The organs consist of numerous fluid-filled pentagonal or hexagonal columns, which essentially act as batteries connected in parallel.
