Excerpt from Travels in Siberia by Ian Frazier, plus links to reviews, author biography & more

On the Risk game board, the lines between regions and around continents were angular and schematic, after the manner of familiar Cold War maps having to do with nuclear war. On the walls at think-tank strategy sessions and as illustrations for sobering magazine articles, these maps showed the arcs of nuclear missiles spanning the globe - theirs heading for us, ours heading for them. Almost all the missile arcs went over Siberia. In the Cold War, Siberia provided the "cold"; Siberia was the blankness in between, the space through which apocalypse flew.

In the best and funniest of all Cold War movies, Doctor Strangelove, the arc of the nuclear bomber sent to attack Russia by the deranged General Jack D. Ripper crosses the war map at the Pentagon slowly, inch by inch, while frantic officials argue what to do. Then we see the plane's pilot, Slim Pickens, in a cowboy hat, and his brave crew. Then there's an exterior shot of the B-52 flying low to elude the Russian radar. Below the plane, practically at its wing tips, rise the tops of skinny pine trees. Then clearings open up, all covered with snow. Then more pines. This can only be Siberia. Suspensefully, the sound track plays "When Johnny Comes Marching Home." As a kid I knew the scenery was probably just stock footage, not really Siberia. Still, it seemed romantic to me - so far away and white and pure. I watched the scenery more closely than the plane.

Cold War movies with happy endings showed the bomber or missile flight paths on the Big Board making U-turns and heading back home or out to sea. Doom had been averted, as the generals threw their caps in the air and shouted for joy. In a sense, that ending actually did occur. The United States and Russia are no longer aiming so many missiles at each other, and you almost never see those maps with dozens of missile arcs on them anymore. The apocalyptic tracks in the sky over Siberia have gone from being hypothetical to being practically nonexistent. Today, Siberia is an old battlefield in which the battle it is known for never took place; the big worries have moved elsewhere.

As a landmass, Siberia got some bad breaks geographically. The main rivers of Siberia are (west to east) the Ob, the Yenisei, the Lena, and the Amur. I have seen each of these, and though the Mississippi may be mighty, they can make it look small. The fact that these rivers' tributary systems interlock allowed adventurers in the seventeenth century to go by river from the Ural Mountains to the Pacific Ocean with only five portages. Seeking furs, these men had crossed all Siberia in less than a hundred years, and built fortresses and founded cities along the way. In western Siberia, there are cities more than four hundred years old. Siberia's rivers still serve as important north-south avenues for barge traffic, and in the winter as ice highways for trucks.

The problem with Siberia's big rivers is the direction they flow. Most of Siberia's rivers go north or join others that do, and their waters end up in the Arctic Ocean. Even the Amur, whose general inclination is to the northeast and whose destination is the Pacific, empties into the stormy Sea of Okhotsk. In the spring, north-flowing rivers thaw upstream while they're still frozen at their mouths. This causes them to back up. This creates swamps. Western Siberia has the largest swamps in the world. In much of Siberia, the land doesn't do much of anything besides gradually sag northward to the Arctic. The rivers of western Siberia flow so slowly that they hardly seem to move at all. There, the rivers run muddy; in eastern Siberia, with its real mountains and sharper drop to the Pacific, many of the rivers run clear.

In general, then, much of Siberia drains poorly and is quite swampy. Of the mosquitoes, flies, and invisible biting insects I will say more later. They are a whole other story.

Another bad geographic break is Siberia's continentality. The land simply stretches on and on; eventually you feel you're in the farthest, extra, out-of-sight section of the parking lot, where no one in the history of civilization has ever bothered to go. Only on the sea can you travel as far and still be in apparently the same place. The deeper into Siberia, the farther from the mitigating effect of temperate oceans, the harsher the climate's extremes become. Summers in the middle of Siberia are hot, sometimes dry and dusty, sometimes hazy with smoke from taiga fires. In the winters, temperatures drop to the lowest on the planet outside Antarctica. In the city of Verkhoyansk, in northeast-central Siberia, the cold reaches about -90°. When I mentioned this frequently noted Siberian fact to my friends and guides in St. Petersburg, they scoffed, as Russians tend to do. Then they said they knew of someplace in Siberia even colder.
