Naomi and I took a trip to the Great Gulf Wilderness Area last weekend. Instead of standing on the head wall of the glacial cirque, we had entered the base of the valley. The Northern Forest is a unique ecosystem that stretches from the Adirondacks in northern New York, through Vermont, New Hampshire, Maine, and into the Canadian maritime provinces. At the base of Mt. Washington, the forest is mixed. The structure is complex: life carves out spaces in a three-dimensional world that stretches from the forest floor to the canopy. Even glacial erratics, large rocks dropped by retreating glaciers, become home to fern, moss, and trees. Click on the image for a larger view.
