1911 -- the family of Steven Rowe Bradley of Nyack, NY honored their father's wish and donated 212 acres on South Mountain to the Palisades Interstate Park Commission. (Binnewies, 2001:73-74) The Blauvelts were an important family in Rockland County. It was one of the best-known and most numerous Dutch families in the county. Four of its members took the oath in 1687. (Talman 1977:9)

Anna Maria De Wint Blauvelt and her husband lived at the DeWint House visited four times by George Washington. Her husband may have been an aide to Washington. Her brother-in-law, Johannis Joseph Blauvelt, was a participant in the Revolutionary War even though he was in his 60s.

The park was named for New York Senator Blauvelt in recognition of his championing the causes of the Palisades Interstate Park Commission. Even after his retirement from politics Blauvelt continued to work for PIPC, this time as attorney. (Binnewies, 2001:87,126)

Located at South Mountain. Tweed Boulevard that borders the park is named for the infamous William M. "Boss" Tweed of New York City. He sponsored a road connecting Hoboken, NJ and Nyack , NJ.

They have old tunnels and rifle ranges . A nearby embankment was the site of the firing line for the pre-World War I firing range of the National Guard Camp known as Bluefield Camp. The National Guard had to abandon the place because the lead from the bullets landed in Grand View to the east along the river. The trees in this part were planted after the camp was abandoned by the National Guard. (Guide to the Long Path, NY-NJTC, 1996:14-15)

In another area the LP crosses an earth-covered concrete tunnel. This tunnel provided safe passage from the firing line to the target wall. The trail continues until it emerges onto Tweed Boulevard.

The Hiram Blauvelt Art Museum of Art in Oradell, NJ is housed in Hiram Blauvelt's 1893 turreted, shingle-style carriage house. In 1957 Blauvelt donated his private wildlife art and big-game collection. Among the exhibits at the museum are a large collection of Audubon folios, natural history dioramas, and artistic works by Carl Rungius and Charles Livingston. (Scheller 1998:8)


The Long Path comes out of the south from Tackamack Park in the town of Orangetown.

Take the blue trail down to a small dam. There is a great marsh area here. The trail then follows the stream leading into the marsh. Cross over the stream, go uphill, to an intersection with the orange trail. The orange trail weaves in and out around the blue trail. If you go east on the orange trail you will go to another dammed area and another great pond and marsh area. Following the orange trail north leads you to a white pine grove and then to an open area and intersection with the blue trail. Following either the orange trail or the blue trail takes one to an open area (a bald rock section) with interesting plants. Shortly after this I turned around and came straight south back to the parking lot.

6/28/02. Parked at the parking area near the intersection of Greenbush Road and Route 303. There is an old asphalt road that heads up the hill going northeast and then bends back southwest and finally straightens out heading north/northeast. There are a great number of invasives here and in places the multiflora rose and Asiatic bittersweet try desperately to block the trail. Going straight you come to the open area mentioned above where the Palisades rock (diabase) is exposed. Still heading north, the hiker finds himself on something like an old causeway. On this the path intersects with the blue trail. Going right on the blue trail takes you down to the parking area at Tackamack Park. Unfortunately, you have to cross over suburban Marsico Road to get there. (The previous time I was at Blauvelt, I don't remember this road being there. Ah, progress, what can I say?)

7/09/02 Walked through Tackamack Park via the Long Path. Went past the open area around the diabase rocks and then out to the remains of the old rifle range?, now much of the concrete bunker covered in painted graffitti. Found mile-a-minute (Polygonum perfoliatum), the first time I have seen the plant in over 10 years of botanizing. It is an easy plant to remember.
