Sugarloaf Mountain or Mount Sugarloaf, is a butte-like mountain located in South Deerfield, Massachusetts, United States, with two summits, North Sugarloaf Mountain 791ft and its more popular knee, South Sugarloaf Mountain 652ft. Its cliffs, made of arkose sandstone, are a very prominent landscape feature visible for miles. Despite low elevations relative to the Berkshire Mountains to the west, dramatic cliff faces and a rise of 500ft to 600ft from the nearby Connecticut River make the mountain a popular tourist and hiking destination. Sugarloaf Mountain is the southern terminus of the Pocumtuck Range.
