GARGANO, MONTE (anc. Garganus Mons), a massive mountainous peninsula projecting eastward from the north coast of Apulia, Italy, and belonging geologically to the opposite Dal matian coast ; it was indeed separated from the rest of Italy by an arm of the sea as late as the Tertiary period. It is of the same character as the Carso, being composed of fractured cal careous rock, and has numerous superficial and subterranean cavities. The highest point (Monte Calvo) is 3,465 ft. above sea level. The oak forests for which it was renowned in Roman times have entirely disappeared except in three sections, and have left the soil dry and stony. Monte Sant' Angelo (q.v.) is the principal town.
