NATURAL FEATURES.
The topographical features of Deer Park are peculiarly marked. There is the broad valley of the Neversink on the east, reaching from northeast to southwest. This soil is exceptionally fertile, and here it was that the early settlers began to build their cabins and blaze their way into the thick forests.
A short, distance from the Neversink stream the old Delaware & Hudson Canal was constructed and operated for many years, the line being nearly parallel to the river. This great coal artery from the mines to the Hudson was, however, abandoned in 1898 after seventy years of successful operation, and the new Ellenville & Kingston Railway took its place.
The Neversink stream has no important tributaries from the east. On the west the Old Dam Kill comes into the main stream at Huguenot. This drains a large portion of the central territory and gives some valuable water power. Basha's Kill is the largest branch entering from the east near Cuddebackville.
The Delaware River separates the town from Pennsylvania on the southwest, and the Mongaup branch of the Delaware divides the town from Sullivan County. Tributaries of this Mongaup stream drain the higher central portions of the town. Still other tributaries of the Delaware flow through the Honesdale region.
The general surface of the town is a mountainous upland broken by many small streams which often flow through rocky ravines. There are steep declivities along the Delaware, Mount William and Point Peter being the most attractive features near Port Jervis. Along Basha's Kill the bottoms are known as the Mamakating valley. Those along the Neversink constitute the Suckapack valley, until the junction with Basha's Kill is reached, when it is called the Neversink valley proper, although also known as the Peenpack. This valley extends to the mouth of the Neversink at Carpenter's Point. If space permitted it would be interesting to trace the origin and significance of these quaint names.
EARLY SETTLEMENT
In 1689 the old town of Schenectady in New York State was captured by the Indians after a bloody fight. Among the residents there who fled from the place was one William Tietsort (now written Titsworth), who came to the land of Esopus first, but soon afterward went to this Minisink region and settled in these forests. After a residence there of some years he sought the right to purchase a tract of land there. This was in 1698, and he succeeded in obtaining the land. His title to this tract, though in dispute for a time, was finally confirmed, and it was excepted from the Minisink patent. This tract was afterward sold to John Decker, and the location is thought to have been near Port Jervis. Thus the honor of being the first settler seems to belong to this William Tietsort.
