Here are several samples of stone walls built by Marc Archambault and Hammerhead Stoneworks.

Stone Wall: Dry Laid Sandstone

The top of this dry stone wall runs level as the bottom rises along a slope. This wall features a mix of several varieties of sedimentary sandstone, mostly from Tennessee. It is a retaining wall, meaning it is structurally built to hold back the bank behind it. This stone wall is located in downtown Asheville, North Carolina.

Stone Wall: Dry Laid Gneiss

This dry stone wall is made of granitic gneiss. This metamorphic stone is common to the mountains of western North Carolina. The mountain building process compressed and twisted granite into this hard and sharp stone, much of which was quarried in Fletcher, North Carolina. This retaining wall is in Montford.

Stone Wall: Mortared of Corinthian Granite

This stone wall features Corinthian granite mixed with locally quarried stone. The white granite upright is quarry waste from South Carolina. This is a mortared, freestanding wall built on a substantial footing. It hides a section of an unsightly interlocking block wall and frames the front entrance of an upscale Asheville home.

Stone Wall: Laid Dry with North Carolina Stones

I like to build stone walls with local stone. This low drystone retaining wall is built of a mixture of stones native to the North Carolina mountains. Drystone retaining walls last longer than their mortared cousins because they are flexible and they drain rainwater effectively. This snow-covered wall is found in downtown Asheville.

Stone Wall: Laid Dry with Granite

This huge retaining wall is built of several varieties of stone. It includes white granite quarry scraps from South Carolina. The biggest stones in this wall weigh half a ton.

Stone Wall: Dry Laid with Gneiss

This dry stone retaining wall is built of Maggie Valley fieldstone. The black and white layered cake look indicates gneiss.
