Bears have the right idea. Don’t fight the cold; just shut ‘er down for six months and emerge when it’s warmer. Why didn’t we think of that? For one thing, our bones would wither. We’d all get osteoporosis, a disease in which bones become more fragile. Bears don’t get osteoporosis, even though they hibernate for more than half the year in Alaska. What might we learn from this? Seth Donahue of...

The year is 1905. You are a prospector in Alaska relaxing in your cabin after a chilly day of working the tailings pile. Craving a cup, you pull a tin of coffee off the shelf. Though you can’t imagine it, that distinctive red can, the one you will later use for your precious supply of nails, will long outlive you. And it will give an archaeologist a good idea of when you made a home in Alaska....

It's early August, 118 miles from the Arctic Circle. Time for a walk to work. The last time I wrote about hiking through the North Campus of the University of Alaska Fairbanks, summer was a puppy crashing into your shin. Now it has a white muzzle. I note this maturity while moving through a nice chunk of boreal forest in the mile between my workplace and my home. For a lot of reasons, I...

Julie Hagelin needed a fake bird. She found one in an unexpected place. The biologist for the Alaska Department of Fish and Game is studying the mysterious olive-sided flycatcher, known for its piercing “quick, three beers!” heard above black spruce bogs throughout Alaska. The bird, which weighs as much as a dozen pennies and migrates as far as Bolivia, is declining throughout most of its range...

On top of an ice body more than two miles thick, Chris Polashenski last summer hoped to find a candy wrapper that might have fallen from Carl Benson’s pocket 60 years ago. As he repeated the Alaska glaciologist’s measurements on the Greenland ice sheet, Polashenski realized that six decades of snowfall, windstorms and glacier movement had wiped out evidence of Benson’s passage. “Carl’s footprints...

Strontium is a trace element and mineral people use to make glow-in-the-dark paints and toothpaste for sensitive teeth. In research for his college degree, Sean Brennan used strontium’s unique qualities to track salmon in an Alaska river. At Brennan’s Ph.D. defense at the University of Alaska Fairbanks, advisor Matthew Wooller praised Brennan’s ambitious plan and his execution of it up and down...

Each fall, white-crowned sparrows hop off branches in Alaska and begin journeys toward California, Arizona, New Mexico and west Texas. On their trip of several weeks, flying mostly at night, the tiny songbirds may cut back on their sleep by two-thirds. Scientists in Wisconsin discovered the sparrow’s apparent ability to perform while cutting rest with the help of a few birds captured in Fairbanks...

Forty-two years ago, an Army helicopter pilot flying over a tundra plateau saw a group of caribou. Thinking something looked weird, he circled for a closer look. The animals, dozens of them, were dead. The pilot reported what he saw to the Alaska Department of Fish and Game. The caribou, 48 adults and five calves, were lying in a group. The way their carcasses rested showed no signs that the...

Alaska’s landscape has an unusual feature that allows us to enjoy cheap bananas in the Interior and other things that make life possible in the subarctic. The Nenana River, born on the south side of the Alaska Range, makes a u-turn and flows north through the mountains. With it comes a wide, low corridor that has favored construction of both the Alaska Railroad and the Parks Highway. “Ordinarily...

A glaciologist once wrote that the number of glaciers in Alaska “is estimated at (greater than) 100,000.” That fuzzy number, perhaps written in passive voice for a reason, might be correct. But it depends upon how you count. Another glaciologist saw an example of the confusion when he visited Yakutat Glacier. Yakutat, near the Alaska town of the same name, is a withering glacier that calves into...
