This porphyritic granite boulder was carried by the last glacier from Mount Monadnock, New Hampshire, to the summit of the hill whose name commemorates it, and for centuries it served as a landmark to Indian and settler. Threatened with destruction by quarrying operations, it was saved by popular subscription and reassembled here in 1929-1930. It weighs 110 tons.
