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.”

Listening to the voices of killer whales
Hannah Myers has listened to many hours of orca calls in the Gulf of Alaska. The University of Alaska Fairbanks graduate student often knows a killer whale’s family group after hearing just a few syllables of its call.

Blown back to Alaska, bird perseveres
A bar-tailed godwit recently arrived in New Zealand on its second attempt to get there from Alaska, after a storm had blasted it back north. Keith Woodley of the Pukorokoro Miranda Shorebird Centre on the North Island of New Zealand reported that a male godwit carrying a satellite transmitter first left the mudflats near the Kuskokwim River on Sept. 11, 2021.

Shorebirds depend on wee slivers of Alaska
Pencil-beaked shorebirds with the ability to stay airborne for a week — flying all the way from Alaska to New Zealand — rely on a few crescents of mudflat to fuel that incredible journey.
Scientists recently found that almost the entire population of bar-tailed godwits that breed in Alaska fatten up on clams and worms on ephemeral sand bars just west of the mouth of the Kuskokwim River. In autumn, 80 percent of the birds rest and feed on islands within 15 miles of one another.

Bus 142 to embark on final journey
“The bus is a touchstone for many things Alaskan: wilderness, exploration, personal discovery, survival,” said Patrick Druckenmiller, director of the museum. “It evokes very strong emotions. It’s exactly for these reasons that the museum is an ideal place to display the bus.”

Red aurora rare enough to be special
Green auroras occur at about 60 miles above Earth. Pure red auroras are much higher, from about 200 to 300 miles up, which allows people closer to the equator to see them. An important gas remaining at that altitude is oxygen, and electrons that excite the oxygen atoms there produce a red light as pure as a laser.

Fluorescent bill may be seabird’s neon sign
The crested auklet looks like a smiling clown that never blinks. It is probably the only seabird that smells like a tangerine. Its beak — the color of a tangerine — is so bright a scientist thinks it may be fluorescent.

Setting traps to catch an Alaska virus
On this crisp, cool fall day in 2021, this trapper — who lives in Atlanta and works for the Centers for Disease Control and Prevention — hunts for a virus that was unknown to humans until 2015. That’s when a Fairbanks doctor examined a lesion on a woman’s shoulder.

Pine grove near Yakutat is farthest north
We were on the Yakutat Forelands — a sweep of forested lowlands left behind after glaciers retreated from the landscape hundreds of years ago. Taking steps that felt like walking on a trampoline, we moved through a pine grove in a few-acre spread of open green muskeg.
The closest people to an 8.2 earthquake
What if the country’s largest earthquake in the last half century happened as you were getting ready for bed in the only cabin on a tiny island in the North Pacific. What if the epicenter was just 50 miles away?
