Stem Rock Natural Area is a beautiful natural rock formation in Searcy County, Arkansas. There is a 3/4 mile trail from the road to the cache and the area has great unique rock formations and beautiful views of the Ozarks. Ammo can container with a bit of swag and a log book for now. The real find here is the uniqueness of the area. There is a sign at the trailhead where you park. No vehicles allowed down the trail, but you can mountain bike down. This is along the Ozark Grinder Bike Trail.
