Introduction to lava landforms: In the Argo Mountains of the Altun Mountain Nature Reserve, there is an ancient lava landform, 350 kilometers long, 20-30 kilometers wide, and covering an area of about 10,000 square kilometers. It is hidden deep in the altitude Among the lofty mountains of 4400-5000 meters. After thousands of years of wind and rain, this ancient limestone mountain has dissolved and differentiated, taking on all kinds of strange shapes. There are many stone peaks, some rising from the ground and reaching into the blue sky; some are lifelike like camels, elephants, blue dragons, crouching tigers, etc.; there are also various ravines, stone buds, corridors and corridors. The karst landform of the Altyn Mountains, due to the influence of Quaternary glaciers in some areas, formed angular peaks that "sweep quietly out of the mountains and abruptly support the blue sky." The karst landforms in the reserve overlap the glacial landforms, with steep cliffs and hanging glaciers, creating a myriad of phenomena.
