The geology of Norfolk County was formed through recurring advances of glacial ice, which not only impacted and distorted the earth’s crust, but also created the present topography through erosion and deposition.
The vast majority of Hale Reservation is underlain by Till or Bedrock, although Sand and Gravel extends across sections of both the western and eastern property line. Ledge outcroppings are prevalent.
Hale Reservation is a treasure trove for geology enthusiasts. In addition to the nine felsite quarries (see Hale History “clickable”) the Reservation abounds with other remarkable geologic highlights. As you drive the main road take note that the road itself is a glacial feature called an esker. Eskers are sinuous, raised formations resulting from by glacial meltwater. From the trails you can see an abundance of other examples of glacial deposition: huge glacial boulders and million of stones used to make the many stone walls on the property. Furthermore each rock outcropping that you visit on the Reservation exhibits the same classic “ramp and pluck” formation and glacial striations indicative of glacial advancement.
