Mount Toby, 1,269 feet (387 m), is the highest summit of a sprawling collection of mostly wooded hills and knolls that rise from a distinct plateau-like upland in the towns of Sunderland and Leverett, Massachusetts, just east of the Connecticut River. This mountain mass, part of the Metacomet Ridge geology, is oval shaped and roughly three miles by two miles wide. Although three of the subordinate peaks have names of their own (Roaring Mountain, Ox Hill, Bull Hill), none of them are noteworthy on their own, and the designation “Mount Toby” is most often used (locally and formally) to describe the entire geologic mass.
