Glaciers radiate from Mount Elbrus, the highest peak of the Caucasus Mountains of SW Russia. Elbrus has twin summits separated by a low saddle; snow-filled craters are visible in this image at both the 5595-m-high eastern summit and the 5633-m-high western summit. Products of Mount Elbrus cover 260 sq km; its longest lava flow traveled 24 km down the NNE flank. Elbrus has been active into the Holocene. Weak solfataric activity near the summit continues, and hot springs are present on the volcano's flanks.
