Basalt Columns: Facts & Uses - Rare Earth Gallery

Basalt is a volcanic rock formed from the superheated magma that emerges as lava during an eruption. The iron & magnesium-rich basalt lava cools & contracts very quickly once exposed to the surface air & hardens or crystalized as it solidifies.

⚡ Quick Answer

Columnar basalt is a dark, iron- and magnesium-rich volcanic rock that cools and contracts into distinctive hexagonal pillars through a process called columnar jointing. Durable and striking, these natural stone columns are widely used for garden fountains and landscape decor. In the crystal community basalt is associated with grounding, stability, and courage, and with the root chakra. Scroll down for how basalt columns form, how they are used, and their meaning.

How Basalt Columns Form

Natural basalt columns are the result of this rapid cooling process that changes the chemical makeup & appearance of the lava.

Columnar Jointing and the Hexagonal Shape

These basalt pillars & hexagonal rock formations you see have a special feature called columnar jointing. This is what gives each basalt column their unmistakable hexagonal shape.

Basalt Columns as Fountains and Garden Decor

Because of their striking geometry and durability, columnar basalt is a favorite natural stone for outdoor decor. It is most often drilled into bubbling water features and garden fountains, and it is also set as standing pillars and landscape accents. Much of the columnar basalt sold for landscaping in the United States comes from quarries such as the Red Bluff basalt of Washington State, prized for its clean hexagonal columns and rich charcoal color.

Frequently Asked Questions About Basalt Columns

What is columnar basalt? ▼

Columnar basalt is a volcanic rock, rich in iron and magnesium, that cooled and contracted into tall hexagonal pillars. It forms when a thick lava flow cools evenly and cracks into a regular column pattern, a process geologists call columnar jointing.

How do basalt columns get their hexagonal shape? ▼

As a lava flow cools and contracts, it shrinks toward evenly spaced centers and cracks apart. Those cracks tend to meet at roughly 120-degree angles, which naturally produces the six-sided columns basalt is famous for. This is why so many basalt formations look like clusters of stone pillars.

What are basalt columns used for? ▼

Basalt columns are a popular natural-stone material for landscaping and decor. They are commonly drilled into fountains and bubbling water features, and are also used as standing garden pillars, stepping accents, and architectural elements. Their durability and clean geometry make them a lasting focal point for a yard or entryway.

Where does basalt for fountains and landscaping come from? ▼

Columnar basalt is quarried in volcanic regions around the world. In the United States, much of the material sold for fountains and landscaping comes from the Pacific Northwest, including the well-known Red Bluff basalt of Washington State, valued for its dark charcoal color and well-defined hexagonal columns.

What is the spiritual or metaphysical meaning of basalt? ▼

In the crystal community, basalt is regarded as a grounding, stabilizing stone. It is associated with stability, courage, and raising energy levels, and it is often used as an anchoring stone during major life changes. These uses reflect cultural and spiritual traditions rather than scientific facts.

What chakra is basalt associated with? ▼

Because of its grounding, earth-connected quality, basalt is most often linked to the root chakra, the energy center associated with feeling secure, stable, and rooted. Many people keep basalt nearby when they want to feel more centered and steady.
