Kà Âmgang is a kun, or county, in Kangwà Ân province, North Korea. Kà Âmgang lies immediately north of the Korean Demilitarized Zone. It was formed in 1952 from a portion of Hoeyang County and from those sections of Yanggu, and Rinje counties that remained under Northern control after the armistice. The county takes its name from the Mount Kà Âmgang, which is partially located there. The county seat, Kà Âmgang-à Âp, was formerly called Malhwi-ri.
The Taebaek Mountains pass through the county, reaching their highest point in the Pirobong peak of Kumgangsan. Approximately 85% of the county's area is forestland. Major local streams include the Kà Âmgangch'à Ân and Tonggà Âmgangch'à Ân.
KÃ Âmgang county is divided into 1 Ã Âp (town) and 26 ri (villages):
The chief local industry is agriculture, with rice and maize the dominant crops. However, arable land takes up only 8.5% of the county's area. Manufacturing and livestock raising also contribute to the local economy. Mining is supported by deposits of gold, tungsten, and quartz.
