Mt. Paektu is standing in the northern part of Korea. It is 2,750 metres above the sea level. It is the highest mountain in Korea. “Paektu” means “white head”.
Mt. Paektu looks white in all seasons, because its ridge is covered with white pumice formed when volcanic eruptions occurred, and also with snow almost all the year round due to low temperature.
The area of Mt. Paektu preserves lots of geological remains created by volcanic eruptions.
There is a volcano crater on the top of the mountain, which was filled with water to form the Lake Chon of Mt. Paektu. The lake is surrounded by sommas consisting of the Janggun, Hyangdo, Haebal, Paegam and Chonmun Peaks, which keep eruptive sections composed of ejecta of several stages of volcanic eruptions.
There are hornitos and hot springs inside the crater. Preserved on the geological section in Janggun Peak is laccolith vividly showing that the rising magma is lifting the upper part.
Also seen are carbonized trees and buried trees, fantastic rocks and volcanic bombs formed by volcanic eruption, and queer rocky valleys formed after volcanic eruption.
The area of Mt. Paektu has a glacial geography well-developed in different ways. It has typical volcanic and alpine topography in northeast Asia.
