Basalt Columns
Basalt Columns are natural rock formations created by the rapid cooling of lava on the earth's surface millions of years ago. Unweathered basalt is black, but after thousands of years of weathering, many more beautiful colors evolve. Various lengths and sizes of basalt are popular in a variety of architectural and landscape uses. Stop in today to see our selection!
