As with the small pond you passed by earlier, this pond likely began as a depression in the glacial moraine that eventually became lined with debris and sediment, which formed a "hard pan" that impeded drainage allowing it to fill with water. You'll notice many trees have fallen into the pond, the shores of which are lined with sphagnum moss and buckbean. It is possible that this pond is in the process of changing into "muskeg," which is a spongy, wet bog. As muskeg is highly acidic, it is difficult for things to grow. This might be the climax development for this part of the forest. However, if this pond were to drain, vegetation and trees might eventually take over. Time -- a long time -- will tell.
