Drystone Walling with Slate
This very linear and even-surfaced material has it's own way about it.
Its flat and squarish shapes make it easy to stack, yet it's brittle nature makes it unpredictable to shape without sawing.
A certain variety, Montana Rustic (a metamorphic sandstone) provides plenty of square corners while the reddish slates have almost no square ends.
This material was chosen to compliment the rustic Corten Steel siding on the house.
The process is painstaking but always very satisfying. Here I am 8 inches from the top in height.
When the greenery grows back in the wall looks very much like it always belonged there.
