From: TheWorldGeography.com

Basalt is a common volcanic rock formed from the rapid cooling of basaltic lava exposed at or very near the surface of our planet. Jointed basalt columns, as the most famous and most beautiful basalt formations, exists on many places on earth. These unusual columns are predominantly hexagonal in cross-section, but basalt polygons with three to twelve or more sides can be observed.

This wonderful cave is located on the Akun Island, one of the Fox Islands subgroup of the Aleutian Islands in southwestern Alaska, USA. Many of the islands of the Aleutians are made up of columnar basalt. Akun Island is also mostly composed of basalt and has several sea caves like this one.

3. Ghenh Da Dia, Vietnam



Ghenh Da Dia is strangely structured rocks include large upright stones equally arranged in a star pattern.

The stones in Ghenh Da Dia are bazan stones of dark black and light yellow. There exists large stones of tons and small stones with different shapes: round, pentagon, polygon and so on. The stones take the right column or a settlement close to each other like disks arranged on couples together. Even counting the stone columns has failed to yield an exact figure as exhausted researchers usually call a halt at around 35,000. The stones are 60-80cm (2-2,5 ft) in visible height and 20-30cm (8-12 inches) across and cluster round a small fresh water pond that is fed by underground rivers and never dries up.
