You’ve probably seen this view without realizing it.

If you’ve ever driven Route 107 and glanced out over the marsh, you’ve probably seen this view without realizing it.

Here is Diamond Creek, the eastern part of Rumney Marsh between Route 107 and the train tracks. On this early October day, the marsh is still a vibrant green with patches of red glasswort, and from above, this section looked exceptionally beautiful, bright, and full of texture.

Diamond Creek is part of the protected Rumney Marshes Area of Critical Environmental Concern (ACEC), a network of tidal creeks and salt marsh that began forming nearly 10,000 years ago as sea levels rose and flooded ancient river valleys. Twice each day, the tide moves through these winding channels, bringing nutrients and life to one of the most ecologically significant wetlands on the Massachusetts coast.

Here, the built world presses close with Route 107 on one side and train tracks on the other, yet the marsh continues its quiet work filtering water, buffering storms, and providing a place for migratory birds to rest.
