Moulton's Mill Preserve Letterbox

Sebasticook Regional Land Trust has a mission to recognize and conserve the rich wild and working landscape of Central Maine. We work with willing landowners to conserve the lands they love and the resources our community relies upon – clean water, family farms that provide local food and jobs, well-managed working forests, places to hunt, fish and recreate with our children.

Moulton’s Mill Preserve is a historically rich area that fronts Twentyfive Mile Stream in Unity, Maine. Sebasticook Regional Land Trust acquired this land in 2012 with the goal of conserving the valuable riparian zone while also offering recreational opportunities like hunting and fishing.

Before this area was Moulton’s Mill, it was known as Samuel Hall’s grist mill, one of the finest in town. After a fire in 1857, the land was bought by Eben Thompson. Thompson operated grist, saw, shingle, clapboard, picket, and lath mills all on one dam. It’s possible that another fire in 1874 burned down these mills, causing Thompson to sell his mill privilege to W.H.J. Moulton.

Moulton then built and operated a saw mill at this location for many years.

• Turn off Waterville Road at the preserve’s trail kiosk
• Once you’re in the parking lot, step over the black erosion net onto the trail to the right, (the one without a rock marker).
• Follow the trail straight ahead and meander up and over the rocks.
• To the left, you’ll see the old mill site.
• Watching your ankles, walk to the left corner rock and look down into the old cellar. Enjoy the view down Twentyfive Mile Stream and notice how powerful the flow of the water is, powerful enough to power Moulton’s Mill.
• Directly behind you is a long rock at the base of a tree. Underneath it and to the left you’ll find the letterbox and a view into the past!
