34 acres


US 287 to US 684 north. Exit 4 Route 172 east. Go 1.7 miles and turn left onto Routes 22/172; travel one mile and turn right in Bedford Village following Route 172 (Pound Ridge Road). Travel 3.2 miles and turn right into the small parking lot of the preserve. (Following the highway distance markers it is at 1079.) It is located shortly after passing Old Corner Road.


The rock is Fordham gneiss, a coarsely banded, metamorphic rock of quartz, feldspar and mica.


Farming here from 1851 to 1936. In 1972 Mrs. Rugh M. Knight donates 20 acres of land in memory of her father. In 1973 TNC purchases an additional 12 acres. And, in 1995, Sid Thompson donates a non-adjacent three acres.


White pine woods, skunk cabbage wetland, Blue Heron Lake, drier woods


It is very hilly here. The blue trail starts at the parking lot making a short counter clockwise circular walk. It heads southwest, then west, then south to the shores of Blue Heron Lake. Turn southeast then northeast and head back to near the start of the blue trail. Near the start of the blue trail there is a yellow trail off the blue trail that heads to a swampy area.

9/29/04.  This day is the day after Hurricane Jane dropped a lot of rain on our area and the trails are wet and have flowing water on many of them. There were lots of broken branches on the trails.  I knocked most of them off the trail with my walking stick.  Took the blue trail heading counter clockwise on the circular loop.  Crossed over a wet area via a boardwalk. There is very little underbrush in the woods.  Come to the intersection with the yellow trail on the right (although at the time I did not realize it). I continued straight. Soon reach Blue Heron Lake.  There are lots of houses on the lake.  There is an interesting white pine area by the lake.  I see an arbor-vitae tree on the large island in the Lake.  There is a small fenced in area near one part of the lake.  The blue trail bears left and heads up the hill via steps. The number 10 marker is located here.  On top of the hill are markers 11 and 12.  Pass the white trail on the left between two parallel stone walls.  Find marker 14 by a stone wall.  Find myself back at the first boardwalk and then back at the kiosk. I wondered why I did not see the yellow trail, so I retraced my steps and found the right intersection (which I had missed before).  I use the boardwalk to get through the swampy area. Get back on the blue trail and head back to the parking lot and my car.
