Mount Toby is a broad, mostly wooded upland in Sunderland and Leverett, Massachusetts, east of the Connecticut River, known for its biodiversity, scenic views, waterfalls, and glacial kettle ponds such as Cranberry Pond. Though linked geologically to the Metacomet Ridge, it is a forested plateau rather than a narrow traprock ridge, with rock layers formed about 200 million years ago through rifting, lava flows, faulting, erosion, and glaciation. Never fully cleared during the agricultural era, it retained extensive woodland and now supports remarkable fern and orchid diversity. Named for Captain Elnathan Toby, it later became associated with Massachusetts Agricultural College and today includes the Mount Toby State Demonstration Forest.
