Hooper’s Creek is quarried in Fletcher, North Carolina- the nearest source of workable building stone to Asheville. It is a type of granitic gneiss, a metamorphic stone that is extremely hard and dense. It has a great texture and it sounds like glass when you hit it with a hammer.
These images show a patio made almost exclusively of Hooper’s Creek. And some pebbles of course. The grain of Hooper’s Creek gives it the sharper angles and straighter lines than the sandstones often used for flagging.
