From the time they thaw in early May, the Ob River and its tributary, the Irtysh, flow from the Altay Mountains of northern China to the Arctic Ocean. The northern reaches of the Ob flow over a flat permafrost plain past the cities of Ozernyy and Nefteyvgansk in northern Russia. Because the river cannot cut deep channels into the frozen land, it spreads out over the surrounding plain during the spring melt, as shown in the image on the right.
