UPDATE, JUNE 3, 2014:

The Spring 2014 of the Hudson River Valley Review includes a new essay about the Northgate estate in Cold Spring. The 11-page article, which I co-authored with Thom Johnson and which borrows from a chapter in Hudson Valley Ruins: Forgotten Landmarks of an American Landscape, written by myself and Tom Rinaldi, shares new research about the development of the estate along with previously-unpublished historic photographs. For more information, please visit the following page:

UPDATE, APRIL 30, 2010:

I am very pleased to announce that historic photographs of the Cornish mansion and estate have surfaced, ending years of mystery in the Hudson Valley for those of us who wondered how the house and grounds appeared before falling to ruin. Please follow this link to see historic images of the Cornish mansion!

I have been in touch with members of the Stern family and recently they informed me of the existence of historic photographs that chronicle the construction and early years of the Northgate estate. These photographs are currently being scanned, and they will be presented in September 2012 during a lecture at the Foundry School Museum in Cold Spring.


One of the great collections of ruins in the Hudson Valley lies on publicly-accessible land in Putnam County. Although the layout of property is well-known to hikers, the early history of the estate is nearly unknown to historians. In 1917, Edward Joel Cornish and his wife Selina Bliss Carter Cornish acquired 650 acres (which they called Northgate) in Cold Spring from a New York City diamond merchant named Sigmund Stern, who built the estate over the previous decade. In the early 1910s, Stern developed an elaborate estate with a mansion, garage, swimming pool, gardens and other outbuildings. Just a few years after construction, and shortly after his first wife passed away, Stern sold the estate to Edward and Selina Cornish, who summered there in 1916. The Cornish name is more often associated with this property, and hikers know the area as the "Cornish estate ruins."

Edward Cornish (1861-1938) was President of the National Lead Company from 1916 to 1933 and lived in New York to be near the company offices. Cornish and his wife Selina, formerly of Omaha, NB, died within two weeks of each other in May of 1938.  A year before his death, Edward Cornish, desiring to protect the estate in perpetuity from the kinds of commercial industrial activities that were occurring at the quarry on nearby Mt. Taurus,  wished to donate his Cold Spring property to New York State upon his death. State parks commissioners rejected his offer, claiming the mountainous terrain was not suitable for a public park, and that it was already protected by restrictions against quarrying.

Nephew Joel O'Donnell Cornish seems to have been the primary responsible party for the Cornish heirs who owned the estate in the following decades. It is believed that the estate was maintained through the 1950s, though perhaps not occupied to the extant it was by the senior Cornishes. A fire in 1958 destroyed most of the mansion; nearly all the woodwork that survived the fire has since disintegrated. All that remains of the structures on the estate are their stone walls. 

When the Cornish heirs sold the estate in 1963 to Central Hudson Gas and Electric, the property again became a focal point of conservation efforts. The regional utility giant briefly contemplated building a power plant on Breakneck Ridge, a fact largely forgotten by historians as this plan was overshadowed by Con Ed's prolonged and publicly-waged effort to build a similar plant across the Hudson River at Storm King. By the end of the 1960s however, the ruins of Cornish estate became part of the newly formed Hudson Highlands State Park and the plans for the power plant was dropped by Central Hudson G & E. The legal battle by conservation groups to preserve Storm King continued into the early 1980s.

In addition to the mansion, other surviving structures include the swimming pool, the greenhouse, and the pump house below to two picturesque waterfalls. At the north end of the 650-acre estate stands a large stone cattle barn. Another large building, possibly a garage, and another small farm building stand in ruins there as well. Even an old wagon rusts away between the barn and the reservoir. Cornish raised prized Jersey cows here and. newspaper articles of the 1920s chronicled the record-setting milk producing efforts of Cornishes dairy cows, including one named "Fon Owlet."  (UPDATE: The reservoir disappeared when the failing dam was destroyed by New York State Parks in late summer 2011.)

Further past the reservoir is Surprise Lake, site of an old but still active summer camp. The Surprise Lake Camp is closely tied to the early history of Northgate. Sigmund Stern was active on the board of the organization that operated the camp, and land transactions occurred between Stern and the camp. The architecture of the main camp building is also similar to the architecture of the Northgate mansion, and the two structures were built just a  few years apart.  The Catskill Aqueduct also slices through the Northgate property, separating the farm parcel from the residential section, and an early 20th-century pump-house can be seen along that trail. 

Marta Dawes's website has information about, and photographs of gravestones of, the Cornish family in Omaha.
