Description
This tuff and volcanic structure clearly illustrates the characteristics of volcanic activities that occurred in the southern area of the Korean Peninsula during the Cretaceous Period, the last period of the Mesozoic Era. Various structures such as cooling cracks of pyroclastic materials of volcanic mountain, as well as tuff and wavy patterns of rhyolite, have great academic value, while the taffoni and net-shaped veinlets create a fascinating landscape.
