Map - Pike County, Pennsylvania (Pike County)

Pike County is a county in the Commonwealth of Pennsylvania. It is part of Northeastern Pennsylvania. As of the 2020 census, the population was 58,535. Its county seat is Milford.

Pike County is included in the New York-Newark-Jersey City, NY-NJ-PA Metropolitan Statistical Area.

Pike County was named for General Zebulon Pike. It was organized on March 26, 1814 from part of Wayne County, Pennsylvania. Some English settlement in the area had started during the colonial years.

The longtime original inhabitants were the Lenape Native Americans, known by the English colonists as the Delaware Indians because their territory was along the Delaware River (as named by the colonists), as well as the coastal mid-Atlantic area. In 1694, Governor Benjamin Fletcher of the colony of New York sent Captain Arent Schuyler to investigate claims that the French were recruiting Indian allies for use against the English. In 1696, governor Fletcher authorized purchases of Indian land near the New York border by a number of citizens of Ulster County; their descendants became the first European settlers of what became Pike County.

Nicholas Depui was the first to settle in the area, in 1725. Thomas Quick moved to the area that would become Milford in 1733. Andrew Dingman settled on the Delaware River at the future site of Dingmans Ferry in 1735. The early settlers got along well with the Lenape and traded with them. As settlement increased and their land practices encroached on Lenape uses, land disputes arose. The colonists' infamous Walking Purchase of 1737 swindled the Lenape out of more than half of present-day Pike County. As the Lenape realized what had happened, violent conflicts arose between them and the colonists.

Early in the nineteenth century, coal was discovered nearby in the area that would become Carbondale. This became especially significant as the British restricted export of British coal to the United States after the War of 1812, creating a fuel shortage in rapidly expanding New York City. To get the coal to New York, developers proposed a gravity railroad from Carbondale to Honesdale, along with a canal from Honesdale to the Hudson River at Kingston.

The state of New York approved the canal proposal in 1823. Work on the 108-mile (174 km) Delaware and Hudson Canal began in 1825 and was completed in 1828. The canal system, which terminated at the Hudson River near present-day Kingston, proved profitable. But the barges had to cross the Delaware via a rope ferry across a "slackwater dam," which created bottlenecks in the canal traffic and added greatly to the cost of transportation.

John Roebling proposed continuing the canal over the river as part of an aqueduct. Built in 1848, his innovative design required only three piers, where five would ordinarily have been required; this allowed ice floes and timber rafts to pass under with less damage to the bridge. Three other suspension aqueducts were subsequently built for the canal. Roebling's Delaware Aqueduct is still standing, possibly the oldest suspension bridge in America; it has been named a National Historic Landmark.

For fifty-one years, coal flowed to New York City via the canal. But the development of railroads, which were faster, cheaper, and operated even when the canals were frozen, brought the end of the canal era. The New York and Erie Railroad supplanted the canal and in 1898 the water route was abandoned.

From 1904 to 1926, Grey Towers in the borough of Milford, Pennsylvania was the site of summer field study sessions for the Master's program of the Yale School of Forestry, together with the Forester's Hall, a commercial building that was adapted and expanded for this purpose.
