bluestone treads

Bluestone is a building stone which is produced in hundreds of small quarries in northeastern tier of Pennsylvania, parts of northern New Jersey and the southern tier of New York.

The best known variety of bluestone is a feldspathic sandstone, which we call Pennsylvania bluestone. The term “bluestone” is derived from a deep-blue-colored sandstone first found in Ulster County, New York created approximately 370 to 345 million years ago in the Paleozoic Era, however, appear in many other hues besides blue.
