From the beginning of May, the temperature has risen above zero in the mountain, with thunders rolling, snowslides occurring and snow thawing in valleys.

The thawing continues until mid-June, forming streams and waterfalls in the mountain.

With the beginning of spring, plants have come into bud and animals have started to make brisk activities.

Birds are coming back from warm areas and chars are seen in unfrozen Lake Chon.

Mt. Paektu is the ancestral mountain marked with the soul of the Korean nation. It is also the sublime mountain of the revolution.
