A working guide to Vermont stone.
What every Vermont landscape stone is, where it comes from, what it does best, and what to avoid. The reference we wish we’d had when we started building stone walls in the Champlain Valley.

Vermont Stone: A Working Guide — and why it matters in Vermont.
Vermont produces some of the finest landscape stone in North America. We’re spoiled — and we should know it. This guide walks through the four primary Vermont stones we use (and one we don’t), where each is quarried, what it does well, and what to never use it for.

What to know.
The working detail — what we apply on every Cairn & Cedar project.
Panton schist
Quarried in Panton, VT (32 miles south of Burlington). Dense, freeze-thaw resistant. The default for retaining walls and stacked-stone garden walls. Color: gray-blue with rust streaks where iron-bearing. Sizes from 6″-cap stones to 200 lb foundation stones.
Goshen stone
Quarried in Goshen, VT. Very dense schist with fine grain. Best for thin-laid wall faces and bluestone-style cap stones. Color: deeper blue-gray. Holds tight joints, ages well.
Vermont granite
Quarried in Barre and Bethel, VT. The hardest stone we use. Best for cap stones, gateposts, and high-traffic walkways. Color: gray with pink and black inclusions. Almost indestructible.
Local fieldstone
Gathered from Vermont fields and farms. Variable color and density — classic ‘New England’ look. Best for naturalistic walls in rural settings. Free or low-cost; selection takes more time.
Vermont marble
Quarried in Proctor, VT. Beautiful but soft. We use sparingly — for sculptural elements, not load-bearing or weather-exposed walls. Spalls in our climate at exposed faces.
What we avoid
Pennsylvania bluestone (too soft for our freeze-thaw), Indiana limestone (spalls), Tennessee crab orchard (wrong aesthetic for VT), imported quartzite (sustainability + supply chain). Local stone is better in every measurable way.
— Frequently asked
What clients want to know.
What’s the most common Vermont landscape stone?
Panton schist by a wide margin. It’s dense, freeze-thaw resistant, available in a wide range of sizes, and quarried close enough to most Vermont sites to keep delivery costs manageable. Default unless we have a reason to specify otherwise.
Why don’t you use Pennsylvania bluestone?
It’s softer than Vermont schist or granite. In our freeze-thaw climate, the surface spalls and the joints crack within 5-10 years. Pennsylvania bluestone is fine for warmer climates; it’s not the right choice here.
Can stone be reused?
Yes. We regularly disassemble and rebuild walls from the 1830s and 1840s — the stone is fine, the build technique often needs to be redone (footings, drainage, cap stones). Reusing existing stone is more sustainable and often more characterful.
How heavy are these stones?
A typical Panton schist ‘face stone’ weighs 30-80 lb. Foundation stones can run 200+ lb. Cap stones 60-150 lb. Yes, our crew lifts a lot of stone — and uses mechanical assistance for the heavy ones.
What about mortar — what type, and why?
Type S mortar minimum for any mortared work in our climate. Type N is too soft and cracks at expansion joints. Type S balances strength with the right amount of flexibility. For large work, a lime-additive mix improves long-term performance.
Is local stone more expensive?
Sometimes slightly more, but the total project cost is usually lower because (a) shipping costs are lower, (b) we know the supply chain so we can match for additions later, and (c) we don’t need to over-engineer to compensate for material weakness.
