Basalt Domes

Basalt columns are volcanic rock. They form when thick lava cools very slowly, and the result is a naturally geometric pillar of basalt. Some of those columns are cut into domes and drilled for water features, and that is what you are looking at here. A dome gives you the solid presence of basalt in a low, rounded shape that sits close to the ground. Anna and the staff can walk you through the pieces on hand and how each one is drilled.

From lava column to dome

The stone starts as a natural basalt pillar, shaped by slow cooling into a geometric column. Cutting it into a dome keeps that volcanic material and gives it a softer outline than a standing column.

If you like the taller look as well, see our basalt columns. Domes and columns are the same kind of rock, so they sit well together in one feature.

Drilled and ready for water

Each dome is drilled so water can rise through the stone and spill over the surface. That makes it a natural centerpiece for a small fountain or a garden water feature.

Tell staff about your setup, including the basin and pump you plan to use, so they can help you choose a piece that fits. Our water feature ideas page is a good place to start planning.

Choosing your dome at the yard

Every dome is a little different, so it helps to pick yours in person at 5300 Excelsior Road. Bring the measurements of the spot where it will sit and a photo of the area.

Stock changes as pieces sell, and special orders are possible. Quotes are given by phone or at the yard.
