What lives in frozen soil for 25,000 years?

In October 2022, Josephine Galipon visited Alaska to see if she could tease out genetic information from gray cylinders of permafrost — silty soil that has been frozen for at least two years, but in this case thousands.

Home insulation from wood and fungus

Robbin Garber-Slaght is a Fairbanks engineer who works for the National Renewable Energy Lab’s Cold Climate Housing Research Center. She notes that Alaskans pay more than double the national average to keep their homes warm during the winter and also pay a lot for sheets of foam insulation, which travels a long way to get here by truck and boat. She is teaming with Phillipe Amstislavski to develop insulation boards made of wood fiber bound by mycelium, the root-like tendrils of fungus.

The man who knew moose like no other

Vic Van Ballenberghe died on Sept. 22, 2022, at the age of 78. The man who knew moose better than perhaps anyone else on Earth had stood amid their knobby legs for many springs and falls in Interior Alaska. I got to join him in the field once, 11 years ago. Here is my story from that day…

Grains of Alaska made into art

Kelsey Aho works as a mapmaker for the U.S. Forest Service in Alaska. She is also an artist who collects earthen materials on her travels around the state. Throughout Alaska, Aho has gathered mineral soils — including clays when she can find them — as well as ash. She has collected from, among other places, the Denali Highway, Hartney Bay near Cordova, the Chilkat River and Murphy Dome in Fairbanks.

Alaska sand dunes hint at ancient past

Sand deposits everywhere in Alaska harken back to a time thousands of years ago when big winds blasted fine particles of glacier-ground mountain a long way. It must have been an unpleasant time to be walking around Alaska, but scientists like Mann are fascinated with what it left behind.

Where do Alaska bats spend the winter?

Jesika Reimer, a bat expert and consultant, has held in her hands little brown bats from the Northwest Territories to the Tanana River. Along with a few colleagues around Alaska, she is sharing new information about the farthest-north bat.

Adopt a woolly mammoth and win!

Adopt-a-mammoth will allow anyone who donates the radio-carbon dating fee of $350 to receive a digital photo of their tusk, femur or whatever mammoth part it happens to be. Scientists will then remove a collagen sample and send it to a carbon-dating lab in California. Mammoth adopters will get results on the age of their animal shortly after the scientists do.

Secrets of an ancient horse of the Yukon

The Yukon — a territory of Canada east of the Alaska border — is a great place to find the preserved remains of ancient creatures. One reason is that the immense ice sheet that covered most of North America (including Chicago and New York City) did not press down on central Yukon nor the middle of Alaska. That spared the landscape from the abrasion of millions of pounds of flowing ice.

A high-country Eden for sockeye salmon

In late summer, a few months before this mossy valley will feel the sting of 40-below air, bright red salmon dart through a crystal-clear pool amid fragrant green vegetation. The Gulkana Hatchery has a Garden-of-Eden feel, which is fitting since millions of sockeye salmon begin life here each year.

A half century in a difficult, dynamic place

Dan Mann hands me a clump of orange dirt the size of an almond. He instructs me to put it in my mouth.
“What’s it taste like? Does it crunch? Ash crunches because there’s glass fragments in it.”
“It crunches.”
“It’s from Mount Edgecumbe,” he says, referring to a volcano 100 miles away, near Sitka. “From an eruption 13,000 years ago.”
