QUIRINO

landlocked province, north central Luzon, Philippines. It has an area of 1,180 sq mi (3,057 sq km) and until 1971 was the eastern part of Nueva Vizcaya province. It is a mountainous region, drained by the upper reaches of the Cagayan River, and parts of it remain little explored. The southern Sierra Madre runs along Quirino's eastern border, and the Caraballo Mountains are in the centre of the province; both contain major timber resources. Rice, corn (maize), and tobacco are grown; the northern part of the province has grasslands. Ifugao and Ilongot peoples live in the region. Cabarroquis is the provincial capital. Pop. (1980) 83,230.
