Here's a new one in SE Connecticut:

Glacial Park

Given enough time and about a million dump trucks, any New Jersey contractor
with connections could pile up enough rubble to recreate Long Island. That
the Wisconsin Ice Sheet took 10,000 years to do it shouldn't be discouraging.
This one mile hike explores a cache of rocky leftovers that didn't make it
out to Long Island, but somehow got dumped in a hollow in Connecticut during
the glacier's retreat. The hike is short, but amazingly rugged due to the
randomly dropped granite and schist erratics you'll be scrambling over.
Figure one hour of stoney enjoyment.

Directions: From I95 in Groton, CT, take exit 86 and head north on CT Rte. 12
for 6.7 miles. Turn right on Rte. 214 East, then after 1 mile, right again on
Avery Hill Extension. At the end of the road, turn left on Whalehead Rd and
watch to your left for the Glacial Park sign under power lines. Park in the
small parking area, and walk left onto the trail bearing 035, away from the
power line gate. Entering the woods, notice sporadic and faint old blue
blazes: although poorly maintained when this letterbox was placed, the blazes
will help quite a bit in keeping you on-trail over the course of the hike.
Soon fork left again at a loop intersection for a clockwise north-to-south
circle around this amazing area. In a short way, cross through a stone wall.
Turn right off-trail about 15 steps along the western side of the wall until
you come to a little drop off. The Boulder Train Letterbox lives here, in the
wall. Now continue with the trail uphill, watching for a sharp right that
will lead you across a zen garden of boulders in a big scattering of rubble.
