Sheffield, established in the mid 1800â€™s was carved out of the wilderness by pioneers and the Seneca native-americans. Located in the heart of the Allegheny National Forest along the Tionesta Creek this area is well known to both anglerâ€™s and hunters for itâ€™s pristine beauty and bounty. In its prime, Sheffield was known for its tanneries and was the last great lumber town east of the Mississippi River. In October, the town hosts an annual Johnny Appleseed Festival. The festival relives the history of the great logging boom through professional lumberjack and chainsaw competition. This family oriented festival includes an apple pie baking contest, chili cook-off, antique appraisals, homemade apple butter and much more. The festival is strategically timed so visitors can enjoy the breathtaking fall foliage that surrounds the community known as the â€œHeart of the Allegheny National Forestâ€.
