Heritage stone from the USA

Jacobsville Sandstone is in addition to being intensively employed locally in the Northern Peninsula (especially in Marquette and Houghton- Hancock) for churches, public buildings, breweries, and residences, the stone enjoyed a wide geographic market. It was shipped as far west as Kansas City, south to St Louis and New Orleans and east to Cleveland, New York and Philadelphia. Duluth, Chicago and Buffalo were the lake ports utilized for inland distribution. The Jacobsville Redstone, more widely used, was available as dimension stone in sizes up to 30 inches thick. In addition to its use as ordinary building stone, surfaces of the blocks could be carved readily into intricate relief designs.
