Figure 3. Digital elevation models showing the extent of glaciation (blue) around Mount Everest. The white boxes show the names of for each glaciation on the northern and southern sides of Mount Everest and the elevation of the equilibrium-line altitude (ELA). The ELA is the line that marks the position where accumumltauon of snow and ice is equal to melting and it provides a quantitative measure of glaciation. The Jilong and Periche I glaciation occurred at ~ 24-38 ka, the Rongbuk and Periche II glaciation occurred at ~ 15-17 ka, and the Samdupo and Khumbu glaciation occurred at 2-7 ka.
