USFS · Campground · Free
As you may have guessed, this campground is located in an old gravel pit. When the excavation hit the water table and the pit was filled in with water the operations ceased and the site was abandoned. Now this campground is locally known as a swimming hole, and is also occasionally stocked with trout.
