It's a small hike up Bearberry Hill to overlook Ballston Beach, but it's worth it to see environmental processes at work. A particularly low dune on the Atlantic face of the Cape was insufficient to hold back an angry sea. Several times since this marsh has been overwashed by the sea. The marsh is the beginning of a small stream called the Pamet River which traverses the width of the Outer Cape and pours out to the bay. In some number of years, the ocean will dig away this sand and create a channel that bisects the landmass. Two houses in this image have been moved in the past two years. See if you can find them.
