Beech Fork River, or the Beech Fork of the Rolling Fork of the Salt River, begins in eastern Marion County, Kentucky, United States. The river heads northwest into Washington County where the Beech Fork connects to the Chaplin River. The Beech Fork River then turns southwest to go through Nelson County. At the end of the river's 125 mile journey[1], near Boston, Kentucky, the Beech Fork dumps into the Rolling Fork of the Salt River.[2]
