Riding on the Ice Road

Southwest Alaska is finally in the comfortable clutch of winter. It is the season that this land knows the best, and is most at home with. When the land is frozen, the air and the people seem to have a liveliness that is missing in the warm months. And the landscape, both in Bethel and in the wild, is much gentler under a forgiving blanket of snow. Winter is good. To be happy here, one must love it.

Sunday, December 24th, was a beautiful afternoon to go out for a truck ride on the river. The weather has been consistently colder than +10F for several days, and the wind has been quiet for the last two days. The day dawned clear and bright just before 11 am and the sun shone strong and low in a deeply blue sky all day. It was a perfect time to be out.

Henry came by in mid-afternoon to see if Dutch and I felt like a short river trip. People have been traveling on the river in cars and trucks for about two weeks now, and the word around town is that the river is safe and the Ice Road is in good condition.

The Kuskokwim River is huge. Eight hundred miles long, up to a mile wide at some points, and anywhere from a few inches to over forty feet deep. In all that eight hundred miles, not a single bridge spans it, not a single dam impedes it. During the winter, the top five feet or so are frozen solid, and the river becomes a highway for all kinds of vehicular traffic. Even heavy fuel trucks are able to drive on the river. It is a little unnerving at first, to be driving a truck where you were driving a boat only a few months earlier, but you kind of get used to it.

Because the lower Kuskokwim is a tidal river, the danger spots from unexpected water are not so much in the center of the river as at the edges. Further upstream several hundred miles, the river is narrow and fast and the center often has open spots due to the churning current. The lower Kuskokwim is much broader and slower; the current does not prevent the center from freezing.

The tidal influence exists for the last ninety miles or so before the river empties into Kuskokwim Bay on the Bering Sea. Once the river’s surface is frozen, the incoming water of a rising tide oozes over the surface of the ice along the edges of the riverbank. It is called “overflow” and may be several feet deep. The surface of this standing water may also freeze over an inch or so before the tide recedes, sandwiching water between the thick plate of river ice and the thin skin of the frozen overflow surface. Snow machines and dog teams can get into serious trouble by breaking through this. There is no current, so you are not washed under the ice to drown. However, if you get wet to the waist in zero degree weather, serious hypothermia can follow if you don’t get dry quickly.

Tidal changes and the natural seasonal decrease in the amount of water in the river also cause the huge plate of ice that is the river’s surface to drop, sometimes five feet or more. This causes large ragged shelves of ice running along the river banks. They must be crossed to get out on to the river where the ice is smooth. In some years, chain-saw ice sculpting is required.

The type of weather we have in October and November determines the quality and character of the Ice Road each year. Each year is different and no two are alike. When we get cold fast and stay that way, the river tends to have a smoother surface overall. This year we had the opposite. Warm weather lasted well into November, with lots of dips and rises above and below freezing. The ice plates that were forming would soften during the warmer hours; then current and wind would shove them together. A temperature drop would freeze everything in place, creating a rough surface of jumble ice that looks somewhat like the moon’s surface.

Depending on the condition of the river ice, the Ice Road may go as far upriver as the village of Aniak, 150 miles away, and as far downriver as the confluence with the Johnson River, about 20 miles. Most years it gets as far up as Tuluksak, about 75 miles away. It always gets to Kwethluk, 15 miles away. In the past, the Ice Road was maintained by the State of Alaska and the City of Bethel; road graders went out on the river and plowed the road to keep it well defined and free of drifting snow. There were even reflective markers occasionally frozen into the ice. The road is no longer maintained, due to liability issues. You’re just on your own out there to find the road and stay on it. Sometimes that is easier than others.

The state of the Ice Road is a popular topic of discussion around Bethel. With the word out that it is in good shape this year, Henry and Dutch and I were curious to check it out. Henry had a thermos of coffee, so we jumped in his truck and took off.

The path on to the river ice is currently good at the small boat harbor. No rough jumble, big dropoffs, or overflow problems. The trail is easy to see and follow. Not much traffic was out; every ten minutes or so, we’d see another car, truck or snowmachine. Every time we stopped to take pictures and drink some coffee, people would stop to ask if we needed help. Every single vehicle. Every time. Not a single person passed us without inquiring. It is very reassuring that if you get stuck, someone will help you.

About five miles upriver we came around a wind-swept bend in the river to find ourselves on the craters of the moon. The jumble ice was so rough and big the road took a serpentine path that quadrupled its length to cover the distance. We bounced slowly along at walking pace for about two miles before the ice was smooth again. Halfway through this section we came upon a man with an ice chisel in his hand, working all alone out on the river. We stopped to talk when we passed him; he said this part of the trail was just too rough, so he was smoothing it out a little. On our way back about two hours later, he had made quite a difference.

The sun was not far from setting when we left town about 4 pm, and much of our ride was in twilight with the moon rising. It was a perfectly beautiful afternoon. Calm and clear with no wind, about ten above zero. Completely quiet, except for the occasional passing truck. We made it almost to Kwethluk before we turned back. It was wonderful to have a little wilderness injection in the midst of the holiday weekend.

Ah, Ice roads. Yup, it's definately a bit unnerving the first few times, but what a great explanation about them.

Beautiful...just beautiful. Both the pictures and your narration. I find myself addicted to Alaska, wishing I were there instead of here in Alabama. Is it possible to be addicted to something you have never experienced? Hoping your holiday was happy and not too busy!!

John--no Ice Road in Houston, ah? Alaska misses you!

TC--what really gets me is when you stop, get out of the truck, and then hear the rifle-shot sound of ice cracking. Intellectually, I know that five feet of river ice are not going to part suddenly and allow my truck to sink to the bottom of the river. But the movie camera in my mind's eye sure does a stunning clip of my truck doing a "Titanic".

Laura--it's not as far as you might think from Alabama to Alaska. I was born there, now I'm here. The climate is a bit more harsh, but the people are sure nice! Get yourself up here for a visit; you'll never regret it. Maybe you'll even decide to stay.

Shinga--thank you!
