granite boulders

Large igneous rocks

Granite boulders are large rounded rocks of granite—a hard, coarse-grained igneous rock.

The phrase describes the massive stones found in mountainous regions, riverbeds, and glacial landscapes, weathered smooth over millennia: The trail wound between granite boulders the size of houses.

In landscaping, smaller granite boulders serve decorative purposes.
