1685  --  the Deed of Sale was approved by King James the Second of England and is known as the Rombout Patent.

1708  --  in the "Great Partition of 1708" the land was divided into three sections. The Verplancks retained the middle section, of which Stony Kill Farm is a part.

c. 1730  --  a colonial-style fieldstone house was built at Fishkill Landing on the Rombout Patent land. It was gradually surrounded by a working plantation, the place being called “Mount Gulian."  It was used as a summer retreat for the family and a working plantation  Along with quarters in Manhattan, the Manor was the home of the Verplancks.

Interpreted Trails

Woodland Trail (easy 1 mile loop)

This easy gravel-lined trail circles through a wooded swamp that was once a farm field. It is now forested by hardwoods.  There is also a wildflower loop for you to explore. A free Woodland Trail booklet is available at the Manor House to help guide and interpret this trail for you.

Verplanck Ridge Trail (approximately 1.5 miles)

This moderate climb leads you through mixed hardwood forest, open meadow, and up to a uniquely wooded ridge top, where thickets and dense vines provide an excellent habitat for various songbirds. The round-trip is about 1 ½ miles on this hard dirt and mowed grass trail.

Sierra Trail (inner loop- one mile; outer loop- two miles)

This double-looped trail takes you through hardwood forest, evergreen forest, wetland, and open meadow habitats, where you are bound to experience a remarkable array of flora and fauna. The footing of the trail is mostly hard dirt with stretches of mowed grass.

Other Trails:

Freedom Trail (2 ½ miles)

One of our newer and more secluded trails wanders across diverse terrain: rock walls, hills, wetland, fields, and forest.

Muller Pond Trail (approximately ½ mile)

Our newest trail takes you through hardwood forest, wetland, and open meadow habitats as you encircle the beautiful Muller Pond. Just over ½ mile hike on mowed grass and hard dirt. It is located just across the road from the Sierra Trail.

12/02/2004.  My brother-in-law Cefe, dog Sonar and I parked the car at the first parking area off Route 9, the lot for Muller Pond.  Wemade the half-mile trek around the area in a clockwise direction.  The opening path is a really wide one.  It looks as if they just recently cut down a lot of shrubs to make the path wider because there were lots of small wooden stumps rising up in the path.  Multiflora rose is a problem and a big nuisance here.  Turned left and passed by one field, over a stone wall and into by another field.  Right turn and we head through another multiflora rose/other invasive species alleyway.  Another right turn and head by another field.  Another right turn and now we can see Muller Pond.  The pond is somewhat semi-circular and not very wide but long.  We see a sign saying "trail" and so follow it into the woods.  This turns out to be a small loop trail because we ended where we started.  So we determined that this time we had to go around the western edge of the pond.  On the western side we finally picked up some trail markers.  From here it was a short walk back to the entrance trail.  A left turn and a very short walk brought us back to the parking area.  Dr. Patrick L.
