Alaska lexicon sinks in over the years

When my little Ford pickup chugged into Alaska 36 years ago this month, I didn’t know a wheel dog from a dog salmon. You could have told me the North Slope was connected to the Panhandle by the Chain and I would have believed you…. I could have avoided that awkwardness if I had possessed the Dictionary of Alaskan English.

The 2 December 2020 Beach Road Landslide in Haines, Alaska

A new open access paper (Darrow et al. 2022) describes the 2 December 2020 Beach Road landslide in Haines, Alaska, which killed two people.

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.

The risk of large rockslides at the port of Skagway in Alaska

Following three failures in the last few years, a new report highlights the risk of large rockslides at the port of Skagway in Alaska.

110 years since the largest Alaska eruption

To put the largest eruption in Alaska’s written history in context, Robert Griggs pondered what might have happened if the volcano that erupted in summer of 1912 was located on Manhattan Island rather than the Alaska Peninsula. “In such a catastrophe all of Greater New York would be buried under ten to fifteen feet of ash and subjected to unknown horrors from hot gases….”

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.”

Bonsai trees tell of winters long past

“These are museum-class bonsais,” Ben Gaglioti says as we walk through an elfin forest. Gaglioti, a University of Alaska Fairbanks ecologist, has led me into another landscape I have never seen in Alaska. This terrace of spongy ground above the rainforest is home to trees that Dr. Seuss might have dreamed up.

Rugged science on the Southeast coast

To the woman wearing earbuds and sitting next to me in seat 7E: I’m sorry; I did not get to shower before boarding the plane after 12 days of accompanying four scientists in the hills north of Lituya Bay. I will try to keep my arms pinned to my side and lean toward the window.

Wading into the icy Yukon River for science

Snow geese flew in a ragged V overhead, rasping as they looked down upon Alaska’s bumpy face for the first time in 2022. Nine hundred feet below, the Yukon River flowed by quietly, except for the dull thuds of icebergs skidding along the river bottom near the shore. Sensing a break in the ice traffic, U.S. Geological Survey hydrologist Heather Best — wearing chest waders with a hole she would soon discover — stepped into the river.

Alaska’s big river breaks up at Eagle

While most of the town was sleeping, the ice slipped out. Breakup happened on the Yukon River here at its first settlement in the United States at around 2 a.m. on Saturday, May 7, 2022. That’s when meltwater rushing from side creeks into the colossal groove of the Yukon lifted a winter-hardened sheet in front of the town.

Awaiting river breakup on the Yukon

Andy Bassich lives on the south bank of the Yukon River, about 12 miles downstream from Eagle, Alaska, the first community in America along the largest waterway in Alaska. Like all of the few-thousand people who live along the big river in Alaska, Bassich hopes that river ice formed by the cold air of winter will continue to disappear in a mushy fashion, one that does not cause flooding.

Alaska’s water crop is a natural resource

As much of Alaska’s landmass crosses the magical temperature threshold that turns ice and snow into water, it’s time to consider the state’s richness in a resource more essential to humans than oil or gas. Clear as gin, brown as iced tea or tinted aquamarine by glacial dust, Alaska’s freshwater supply is so abundant the numbers are hard to comprehend.

His 48th summer on top of the world

This June, George Divoky will refurbish a cabin that sits on a lonely gravel island north of Alaska. He was not planning a remodel this year. Sometime during the winter, a polar bear tore through a plywood wall of the cabin Divoky moved 20 years ago to Cooper Island.

Live-trapping lynx in the far north

Knut Kielland, a professor with UAF’s Department of Biology and Wildlife, used to trap lynx for their fur. Here, he has captured this 22-pound female lynx as part of an Alaska-wide project he leads to better understand the ecology of the animal.

Happenings north of the Arctic Circle

Though the calendar calls it springtime, the thermometer on the truck reads minus 28 F on this sunny morning a few days past spring equinox. I am riding shotgun with Knut Kielland, an ecologist at the Institute of Arctic Biology at the University of Alaska Fairbanks. He has invited me to join him for a week north of the Arctic Circle — 66.6 degrees north latitude, about 150 miles from Fairbanks.

Caribou cams give insight into secret lives

Caribou wearing cameras around their necks have filmed a secret world of mushroom nibbling, desperate head-shaking during bug episodes, and nuzzling of wet newborns seconds after they fall to the tundra.

Thirty years on semi-solid ground

At the end of this month, Vladimir Romanovsky will retire after 30 years as a professor and permafrost scientist at the University of Alaska Fairbanks’ Geophysical Institute. This comes at a time when people — finally — no longer squint at him with a puzzled look when he mentions what he studies.

Elephant Point and trees growing on ice

Librarian Judie Triplehorn solved the mystery of Elephant Point with a yellowed document she placed on my desk. In it, a writer for the Edinburgh Museum in Scotland in 1829 hailed the arrival of “two tusks of the Mammoth, brought home by Captain Beechey.”
