The southwest portion of the county is bounded by the Masingryŏng and Taebaek mountains, which meet at the pass of Ch'ugaryŏng.

There are local deposits of gold, silver, copper and zinc, but they are not widely exploited.

A chemical weapons storage facility is believed to be located in the county's Chiha-ri precinct.

The facility is said to include numerous tunnels dug deep into the mountains, and may also host some biological weapons.
