Not sure what your question refers to, but we’ll attempt to answer it in two ways.
Learn About Shale is an community conversation sponsored by the Marcellus Shale Coalition to answer questions of those who live and work in the commonwealth. As a Pennsylvania-based trade association, we want to ensure that our friends and neighbors have their questions answered in a straight-forward and fact-based manner.
If you’re question refers to the Marcellus formation itself, and why “it” is in Pennsylvania, that’s a question of geology. The Marcellus Shale formation is roughly 95,000 square miles and spans five states (New York, Pennsylvania, Ohio, West Virginia and Kentucky). To learn more about the formation itself and how it was created, we encourage you to visit the Pennsylvania Department of Conservation and Natural Resources Marcellus Shale webpage.
