The Mine Brook section would be one of these. It is essentially a wetland protection buffer for the Walpole water supply. A run of eskers, almost in a skein, makes a dogleg with a short southerly bit bending to a longer easterly one. The trail begins its easterly run to Duxbury in a stepwise fashion.
It is also a headwater of the Neponset River watershed.
This has been a very valuable basis for piecing continuity together to thread through the fragmentation of settlement patterns and invoke some sense of pre-colonial potential.
The actual wetland is a coy thing beyond a screen of pines, for the most part, with occasional touches and glimpses.
And the far shore carries the bed of a CSX freight line that sometimes accompanies the hike with the stutter whir of its distant engines.
The section nearest Robbins Road generally gets more use than the rest.
And a howitzer greets you when Robbins Road meets you. From there, it is a pleasant foray through downtown Walpole before heading to Sharon.
