About Agassiz Rock

Ascend a small hill to where a massive granite monolith left by the last glacier juts into the sky, then pass a swamp where another huge boulder has sat as silent witness for millennia.

What makes Agassiz Rock a special place?
Big and Little Agassiz Rocks are dramatic examples of giant boulders plucked from bedrock and carried far away by the last glacier. A short loop trail leads you up Beaverdam Hill where Little Agassiz Rock emerges as a giant granite monolith silhouetted against the sky. A short distance away, other boulders lie perched on the edge of this glaciated upland. Below, in a small shrub swamp, rests 30-foot-tall Big Agassiz Rock. No one knows how far below the ground it is buried.

As the glaciers scoured this landscape, the mass of bedrock forming the hill proved more resistant than the surrounding soil, forcing the bottom of the glacier up and over the hill. The north side was smoothed and the south side left steep and rugged as the glacier broke off chunks of rock as it passed.

Trails
1-mile loop trail (moderate hiking) takes in both Big and Little Agassiz Rocks. Following long periods of rain, when the water table is high, the immediate area surrounding Big Agassiz Rock can be flooded.

Property History

In October 1874, a group of students from the Essex Institute formally named the site to honor Louis Agassiz (1807–1873), the professor of natural history at Harvard University who first theorized that the rocks that dot New England’s landscape were shaped and deposited by glaciers. Agassiz supposedly visited the site at the suggestion of its then-owner, Frederick Burnham.

Agassiz found its erratics great lessons to advance his theory and to bring it to the attention of science. Prior to Agassiz’s theory, it was widely believed that the scattering of rocks throughout New England were the result of Noah’s great flood.

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.

This is a wonderful walk, and the special treats - awe-inspiring Big Agassiz and the quirky perch of Little Agassiz are fun to discover. The hike is not too long or steep, and the view from the hilltop is nice. Itis certainly not overcrowded - I think we met only two people on a pleasant September weekend afternoon.
