Mt. Chilbo in North Hamgyong Province in the northern part of Korea is one of the six celebrated mountains of Korea. From long ago Rojok or Grain Stack Peak was widely known in Mt. Chilbo for the regular and well-developed cleat of its rocks.
As the name says, the peak looks like a high stack of tens of thousands of rice sacks. It is 50 metres high and of conical shape.
Pine and maple trees are growing at every cleat of the peak and the clear water of the Pochon Stream is flowing under it.
The queer Rojok Peak is a very rare peak, which is of great significance in studying the process of formation of cleat of rocks and the topography of the Paektu volcanic belt. It is also a precious natural monument adding beauty to Mt. Chilbo.
