Mountain Province (Tagalog: Lalawigang Bulubundukin), is a landlocked province of the Philippines in the Cordillera Administrative Region in Luzon. Its capital is Bontoc. Mountain Province is sometimes incorrectly named Mountain in some foreign references. The name is also incorrectly shortened by locals to Mt. Province, which in turn is read by native Anglophones as "Mount Province". The province was named so for being in the Cordillera Central mountain range found in the upper realms of Luzon island.
Mountain Province was also the name of the historical province that included most of the current Cordillera provinces. This old province was established by the Americans in 1908 and was later split in 1966 into Mountain Province, Benguet, Kalinga, Apayao and Ifugao.
Mountain province is known for its mummy caves which contain naturally mummified bodies which probably became so due to the humid atmosphere. The hanging Coffins are also found in the province, these are literally coffins hanging on to the branches of trees, many tourists claim there is no foul odor, the bodies were probably mummified by the atmosphere according to theory.
