The rolling hills and mountains here have given it the nickname Mountain State. It is the only state within the Appalachian Mountains. Logging, coal mining, oil, and natural gas extraction were its main economy providers. It supports outdoor recreations like skiing, fishing, white-water rafting, hunting, and so on. It is home to the longest steel-arch bridge in the west built on River Gorge at Fayetteville. Activist and author, Pearl S Buck was born here.
