Noting that, "In prehistoric days the Dzungarian Gate must have presented a still more wonderful sight" when it "formed a narrow strait joining the Dzungarian inlet with the vast seas of Western Siberia," Carruthers quotes the British journalist and MP, Morgan Philips Price, with whom he travelled:One can picture the Dzungarian Gate in the Ice Age: a narrow strait through which the Arctic-AraloCaspian Sea ebbed and flowed into the seas of Central Asia, scoured by icebergs descending from ancient glaciers on the Ala-tau and Barlik Mountains and forested perhaps down to the water's edge,—not unlike the Straits of Belle Isle at the present day. Now a change has been wrought; earth-movement has drained the sea. But away to the north there still remain the lakes of Ala Kul, Sasik Kul, and Balkash, and on the south Ebi Nor,—pools left in the desert—all that remains of the great icy sea. The alluvial plains, once its bed, are now covered by desert grasses, while the forest clings only to the shaded slopes and gullies on the northern slopes of the mountains.
