Sugarloaf Mountain or Mount Sugarloaf, is a butte-like mountain located in South Deerfield, Massachusetts, United States, with two summits, North Sugarloaf Mountain 791 ft (241 m) and its more popular knee, South Sugarloaf Mountain 652 ft (199 m). Its cliffs, made of arkose sandstone, are a very prominent landscape feature visible for miles. Despite the low elevation of the summits to the nearby Berkshire Mountains, dramatic cliff faces and a rise of 500 to 600 feet (180 m) from the nearby Connecticut River make the mountain a popular tourist and hiking destination. Sugarloaf Mountain is the southern terminus of the Pocumtuck Range.
