Beautiful Minnesota field stone showing its "glacial" character

One of the great things about stone is that there are such distinct regional differences. Stone one might find just laying about in a field in one region is often devalued by the local residents because they see it everywhere. In Minnesota, what we call “field stone” is a random assortment of rounded rock in all different colors and sizes. We also call it “glacial boulders”, which defines more closely the character and source of this rock.

The rounded shape and colors that range from pink and white, to blue and dark red, define its geologic past. This rock we see stacked in huge suburban retaining walls and the “river rock” we see in shopping mall shrub plantings is the result of the glaciers pulling rock from a variety of northern sources, tumbling it over thousands of years and dropping it randomly on the landscape. Its kind of like “stone washed” jeans - these rocks have a lived-in look.

While its ubiquitous nature leads to it feeling kind of common, it really is our “native rock” and can be used in ways to accentuate its nature rather than just to solve maintenance problems or cover space.
