Ritual In The Woods

I'm not entirely certain what is going on here. This site was located about 3 metres away from a campsite and the passing pedestrian trail. It doesn't appear to have a practical purpose as there would be no reason to light a fire in a pit so close to a proper campfire ring. I'm guessing this was something set up by kids, but it's still unusual enough to mention here. It is located in Inverhuron Provincial Park, Inverhuron, Ontario, Canada.
