drift ice tour map

When the water of Siberia's great Amur River flows into the Sea of Okhotsk, it freezes into chunks of ice. These chunks bump into each other and combine into ever-larger chunks which drift southward to the coast of Hokkaido, Japan from mid-January to March. Those who are willing to brave Hokkaido's frigid winter temperatures can experience this silvery-blue wonderland of ice, and the rich and varied ecosystem that accompanies it.

I submitted this to They Draw and Travel, like I did the other three maps. I hope they're not getting sick of me. :p

And since this phenomenon occurs year after year, I've decided to let this count as my Illustration Friday submission for the topic "perennial."
