Harriman State Park, Orange County, NY


Tappan Zee Bridge; exit 13 for Palisades Interstate Parkway North. Get off at the left exist for Lake Welch. Follow the signs to Tiorati Circle. At Tiorati Circle take Seven Lakes Drive 2.5 miles south past the south end of Lake Tiorati and then pass Lake Askoti on the right and turn right into the parking area by Lake Shannatati.


The mine takes its name from the nearby wetland, Pine Swamp. It is located in the area around the junction of the red-triangle Arden-Surebridge Trail and the yellow-blazed Dunning Trail in Harriman State Park. The mine is on the hillside located 900 feet south of the intersection of the Dunning Trail and the Arden-Surebridge Trail.

This mine was owned by Robert and Peter Parrott (also owners of the Surebridge Mine). The ore went to the smelting furnaces at Arden, NY. (Lenik 1996:102-105)


Park at the parking area at lake Skannatati. Take the red-triangle Arden-Surebridge Trail to the area known as Times Square. From here walk north on the trail for 500 feet past where the blazed trail turn left; stay on the old woods road (the Surebridge Mine Road) north. Surebridge Swamp is on the left. The mine is on the right at the northern end of Surebridge Swamp. There are a total of eight mine openings in this area.

The mine was owned by Robert and Peter Parrott in the 19th century, particularly during the Civil War. The ore went to the Greenwood Furnace at Arden, New York for smelting. (Lenik 1996:105-107)


I did not get very far on this trip as there was too much botany to look at.  But you can use Peggy Turco's book for a longer walk.  I walked on the Long Path (turquoise markers) along the northern shore of Lake Skannatati.   I did make it to the intersection with the yellow trail. I found a Phragmites australis (giant reed grass) marsh.  I did find the cotton grass here. Came across five wild turkey in a group.  I made it to the top of a hill and then just turned back. There were quite a few trees down on top of the mountain.

9/18/01. Take the Arden-Surebridge Trail (A-SB). Head up the steep Pine Swamp Mountain (with some rock slight climbing). Great view southwest from here of Lake Skannatati and Lake Kanawauke. Pass several old mine holes and then come to a really large mine cut, both on the right side of the trail. Pass by the Dunning Trail (Yellow Blazed). Reach Times Square where three trails meet (A-SB, Ramapo-Dunderberg (R-D), and the Long Path). Continue on the A-SB Trail. As the trail turns left, continue straight on the Surebridge Mine Road. Here is Surebridge Swamp. The dominant species seems to be highbush blueberry with some red maple. Continuing on the A-SB Trail takes the hiker to the Lemon Squeezer near Island Pond.

Returning, took the Dunning Trail (yellow blazed). Pass the large Pine Swamp with lots of leatherleaf around the edges. On the left are the remains of a large mine. Turn left onto the Long Path (turqoise blazed); walk parallel to the edges of Lake Skannatati. Return to the parking lot.

July 12, 1936

Surebridge Swamp, a high, cold, forested swamp, at an altitude of about 1,000 feet, in the western part of the Harriman Section of the Palisades Interstate Park, was visited on July 12. A new station was found in the depths of the swamp, unusually penetrable owing to dry weather, for the Virginia Chain fern, Woodwardia virginica. The red fruited sorediate lichen, Cladonia incrassata, not common in the Hudson Highlands, was rather extensive here about bases of red maple trees. On the "Lichen Trail," climbing the ledges of Hogencamp Mountain, the only really ample station in the Hudson Highlands, of the Iceland Moss lichen, Cetraria islandica, was noted, other lichens . . .
