About Bartholomew's Cobble

Created by geologic upheavals when the Taconic and Berkshire ranges were formed, this hundred-foot-high bedrock outcropping introduces visitors to a rugged and exotic landscape that also supports 800 species of plants while offering terrific mountain vistas.

What makes Bartholomew’s Cobble a special place?
We think it’s the twin rocky knolls that give this rare, geologic phenomenon its intriguing name. Probably taken from a German word, kobel (meaning “rocks”), the Cobble began as coral reefs, shells, and sand as many as 500 million years ago when this area was an inland sea. When the Taconic and Berkshire mountains were formed, the still-forming strata were pushed upward and flipped over, leaving the rough and rugged underbelly exposed for millennia. The reservation’s more recent farming history lives on through herd of cattle grazing along the river.

The cobbles consist mostly of quartzite and marble, whose alkaline soil supports an unusual array of flora – you’ll find one of North America’s greatest diversities of fern species here. The reservation also boasts one of the largest Cottonwood trees in the state. It’s this amazing diversity that led to the Cobble’s designation as a National Natural Landmark in 1971.

The high point at Bartholomew’s Cobble, Hurlburt’s Hill, rises 1,000 feet to a 20-acre upland field on the Massachusetts–Connecticut border that offers panoramic views northward up the Housatonic River Valley.

You can tour the cobbles, trees and understory plants, and river, on the Ledges Trail, which also passes two small caves kids love to explore. You can also trek through open fields, transitional forest, and freshwater marshes with beaver ponds along the Cobble's other trails. Don't forget to stop in to the natural history museum and visitor center either before or after your visit. And, to mix your natural history with some cultural history, follow the trail that leads to the nearby historic Ashley House, from where enslaved African American Mum Bett Freeman sued for her freedom, helping to end slavery in Massachusetts.

Five miles of trails, moderate hiking. Some may find the hike to the Hurlburt's Hill summit strenuous.

Property History

The reservation is named for George Bartholomew, a farmer who purchased the fields and uplands in the late 19th Century. But more than a hundred years earlier, Col. John Ashley had gathered together a sprawling estate of which the current reservation was only a part. The Trustees acquired the Cobble in 1946; Ashley’s home, also owned by the Trustees, still stands on nearby Cooper Hill Rd.

Property Acquisition History
Original acreage purchased in 1946. Additional land purchased in 1963, 1968, and 1969, and in 1976 with a matching grant from the National Park Service and the Massachusetts Historical Commission. Additional land given by Ellen Spero Roman and James S. and Robert E. Spero in 1978; Antonio J., Gilbert F., and Vincent A. Malnati in 1981; Harry Kahn in 1982; Dr. Alan J. Frish in 1982; and Ann Z. Grumpelt in 1996 and 2000.

Conservation and Stewardship

Management Planning for Our Properties

Since 1891, The Trustees of Reservations have worked to protect special places in Massachusetts and maintain them to the highest standards. To ensure these standards are met, a program of careful planning and sound management is essential. Comprehensive property management plans are created for each reservation and are completely updated approximately every ten years. We often work with volunteers, property users, and members of the community to carry out this planning, which typically involves several steps:

  • Describing in detail the site’s natural, scenic, and historical resources; identifying management issues related to the protection of those resources. 

  • Describing how visitors use the property; outlining the opportunities that the property provides for people to become involved in the work of conservation and caring for their community.

  • Developing a detailed list of management recommendations, a work plan, and a description of financial needs for implementing the actions.

  • Developing a prescribed routine management program for the reservation that will guide staff work plans, volunteer involvement, and the allocation of human and financial resources.
