There is a small blue-blazed loop in this area, signage calls it "Stone Road bypass". It goes north from the marked spot about 100 yards, then bends west to return to the main trail. It does not show on the town trail map. https://littletonconservationtrust.org/property/robert-and-emily-cobb-memorial-forest/

This section is also blue-blazed, N and NW to yellow main loop.

There's an official blue-blazed trail that runs NNE to the midpoint of the property line that runs NW to SE. There's a branch connecting to the yellow trail, along the previously mentioned property line. The main blue trail continues NNE and becomes the Sprong Trail, ending at Tahattawan Rd. https://littletonconservationtrust.org/property/newtown-hill/

There is an additional piece of LCT property in this area. There is a yellow blazed loop, a blue-blazed connector to the yellow trail on Newtown Hill (runs alongside the short SW to NE property line), and a connector that runs south to Boxborough Road. https://littletonconservationtrust.org/property/newtown-hill/

This section of trail has blue blazes, and goes NE along the shore (further than shown on map) and connects with the yellow trail. Trail is pretty wet and infrequently used along the pond.

This trail section is closed for repair/maintenance.

Yellow blazes.
