Offering a luscious landscape and intriguing geological artefacts, the volcanoes of the Jingbo Lake National Geopark in the Mudan River of Northeast China's Heilongjiang Province are a sight to see.

Dubbed a "volcanic museum" in China, the Jingbo Lake National Geopark is known for its volcanic group and lava-blocked lake, which is one of the largest in China.

Situated in the city of Anning, the park rests between the Zhangguangcai and Laoye Mountains. It rises high in the southwest and low in the northeast, with an altitude ranging from 241 to 1,109 metres above sea level.

The Jingbo Lake, formed by lava flow that blocks the course of the Mudan River, has a vast area of 79.3 square kilometres, or 2.8 times the total water area of the five lakes in Heilongjiang's Wudalianchi World Geopark, another world famous volcanic site consisting of five linked lakes.

There are 16 cone-shaped volcanoes in the park, distinctive with different scales, structures and unique characteristics.

Spectacular volcanic remains in the park include a lava river stretching more than 60 kilometres and a huge valley lava mesa with an area of 200 square kilometres, both of which are rare not only in China, but in the rest of the world as well.

The underground forest lava and cone-shaped volcanoes are well preserved in the park. The underground forest lava, running a length of 65 kilometres, is truly a sight to behold.

With an accumulated length of more than 20 kilometres, the underground lava tunnel is full of mysteries, geological experts claim. Inside the tunnel, various macro-geomorphic views are well preserved and can be clearly defined, such as lava stalactites, lava bed, lava basin and lava strips.

Formed by the collapse of lava tubes and the erosion of rivers and streams, the Diaoshuilou Waterfall transfers water from Jingbo Lake to the Mudan River.

It is the only lava-caused waterfall the world has ever reported. Among China's six famous waterfalls, the Diaoshuilou Waterfall and the Hukou Waterfall along the Yellow River are the only two with ice waterfalls in winter.

Besides rich volcanic relics and water views, the geopark is abundant with granite physiognomy landscapes, biological landscapes and humanistic scenic spots.

The exposed granite area is 1,143 square kilometres in the park. Granite hills and granite forests formed by erosion and weathering along the riverside are a direct contrast with the soft water views.

The park also preserves the original village relics of the primitive society, Chengzi Houshan city relics of the Liao and Jin dynasties (916-1234) and Sanqingguan relics of Ming and Qing dynasties (1368-1911).

The volcano park's physiognomy and lava-blocked lake are paragons of natural beauty and have high scientific, aesthetic and historical values.
