Old Stone Fort State Archaeological Park Nature Trail

The trail begins shortly past the Old Stone Fort visitors center on a dirt path rich with the roots of giant oak trees. After coming to the first of many forks in the trail, taking the right choice (no pun intended) will lead down gradient to the banks of the Duck River. Along the Duck River, the trail consists of root systems from surrounding oak trees and fragments/outcrops of the limestone and shale bedrock. Continuing in a southwestern direction, the trails will pass through the block remains of what was once a paper mill; a main distributor of paper to Atlanta, GA & Nashville, TN in the late 1800s to early 1900s (look up if you're a history enthusiast). The paper mill is positioned in the vicinity of Big Falls which is a sight to see. While not the most spectacular waterfall the state of Tennessee has to offer, the geology enthusiasts will be pleased with the stair-step illusion from the weathered limestone of which the water falls upon. Big Falls is approximately fifteen to twenty feet tall, but the pool of water below (unknown depth) is the site of a lot of swimming during the summer months (not sure if the park is okay with this; please check and if so, please swim at your own risk). Following Big Falls, the trails will continue in a south-southwestern direction along a dirt path, scattered with occasional benches for resting (if needed). At about 0.50 miles, the trails will begin on a downhill slope towards the Fork of the Rivers Trail (Little Duck River merges with "Big" Duck River). Another fork in the path will force hikers to choose left or right; taking a right will lead hikers along a moderately narrow trail with uneven terrain right on the edge of Little Duck River (red trail). Taking a left (green trail) will lead hikers along a more even terrain path through the forest where the hiker will be provided with another fork in the path. Taking a left will remove approximately 1.40 miles of the above referenced route (green trail); taking a right will take the hiker on a reverse path than what is depicted above (red trail).For the purposes of this route, taking a right at the Fork of the Rivers Trail will shift the trail in a south-southeastern direction. For the next 0.75 miles, the trail will oscillate along the uneven terrain along the perimeter of Little Duck River. Along this path, the hiker will observe various wildlife, flora, fauna, and geology of the area. At approximately 1.18-25 miles, the trail will shift to a north-northwest direction. Around 1.30-40 miles, the trail will pass through an old river bed and meet up with Grindstone Hollow Creek. It is here that hikers may rest before the uphill along the Backbone Trail; many pretty "river rocks," fossils, and geodes are found here. Continuing along, the trail will begin its ascent up what is know as the Backbone Trail. For approximately 0.25-30 miles, the trail will ascend quickly up roughly 100-150 feet to the ridge of the limestone bluffs. Once on top of the ridge, the views of the Little Duck River and the surrounding area are spectacular, especially during fall color change. At almost 1100 feet, this is one of the highest peaks during the hike. After coming down the Backbone Trail, hikers will want to take a right at both forks in the trail soon thereafter. Taking a left will lead hikers back to the Forks of the River Trail... if doing the trail over again is warranted, then go left!After taking two rights along the trail, hikers will find themselves on the Moat Trail (I believe a former river bed of the Duck River). For less than a quarter of a mile, hikers will pass through a wooded forest (I always see Pileated Woodpeckers here!). Following this trail around the upcoming bend will take hikers along Little Duck River to Step Falls. Here, hikers will observe a small waterfall and a nice resting area. Afterwards, the trails will meet up with the Enclosure Trail and lead hikers back to the Old Stone Fort Visitors Center.

Old Stone Fort State Archaeological Park is the grounds of an ancient Native American (Middle Woodlands Period) ceremonial gathering mound. Many experts believe this site was not a sacrificial or religious place; it is believed to be a place where astronomical events took place.Additionally, an old paper mill is found here.
