The Sohung River Valley is located in North Hwanghae Province in southwestern North Korea, serving as a primary component of the regional lowlands. The Sohung River originates in the Ahobiryong Mountains and winds for over 100 kilometers through a hilly landscape before joining the Ryesong River. The valley is famous for the artificial Sohung Lake, created in 1945 by damming the river to facilitate irrigation. The region is considered one of the most fertile areas in the country, as its alluvial deposits provide convenient conditions for large-scale rice cultivation and fruit orchards. Geomorphologically, the valley consists of gentle rolling hills formed from Mesozoic sedimentary rocks, providing a sharp contrast to the rugged mountains to the east. Historically, the valley was a vital strategic corridor between Pyongyang and Kaesong and played a significant role in various conflicts throughout Korean history. Today, the valley is intensely cultivated, with the river's water resources being crucial for both agriculture and local industries.
