“Dog is man’s best friend” may be an ancient cliché, but when that friendship began is a longstanding question among scientists. A study led by a University of Arizona researcher is one step closer to an answer to how Indigenous people in the Americas interacted with early dogs and wolves.

The study, published in the journal Science Advances and based on archaeological remains from Alaska, shows that people and the ancestors of today’s dogs began forming close relationships as early as 12,000 years ago—about 2,000 years earlier than previously recorded in the Americas.

“We now have evidence that canids and people had close relationships earlier than we knew they did in the Americas,” said lead study author François Lanoë, an assistant research professor in the U of A School of Anthropology in the College of Social and Behavioral Sciences.

“People like me who are interested in the peopling of the Americas are very interested in knowing if those first Americans came with dogs,” Lanoë added. “Until you find those animals in archaeological sites, we can speculate about it, but it’s hard to prove one way or another. So, this is a significant contribution.”

Lanoë and his colleagues unearthed a tibia, or lower-leg bone, of an adult canine in 2018 at a longstanding archaeological site in Alaska called Swan Point, about 70 miles southeast of Fairbanks. Radiocarbon dating showed that the canine was alive about 12,000 years ago, near the end of the Ice Age.

Another excavation by the researchers in June 2023—of an 8,100-year-old canine jawbone at a nearby site called Hollembaek Hill, south of Delta Junction—also shows signs of possible domestication.

The smoking gun? A belly of fish

Chemical analyses of both bones found substantial contributions from salmon proteins, meaning the canine had regularly eaten the fish. This was not typical of canines in the area during that time, as they hunted land animals almost exclusively. The most likely explanation for salmon showing up in the animal’s diet? Dependence on humans.

“This is the smoking gun because they’re not really going after salmon in the wild,” said study co-author Ben Potter, an archaeologist with the University of Alaska Fairbanks.

The researchers are confident that the Swan Point canine helps establish the earliest known close relationships between humans and canines in the Americas. But it’s too early to say whether the discovery is the earliest domesticated dog in the Americas.

That is why the study is valuable, Potter said, “It asks the existential question, what is a dog?”

The Swan Point and Hollembaek Hill specimens may be too old to be genetically related to other known, more recent dog populations, Lanoë said.

“Behaviorally, they seem to be like dogs, as they ate salmon provided by people,” Lanoë said, “but genetically, they’re not related to anything we know.”

He noted that they could have been tamed wolves rather than fully domesticated dogs.

‘We still had our companions’

The study represents another chapter in a longstanding partnership with tribal communities in Alaska’s Tanana Valley, where archaeologists have worked since the 1930s, said study co-author Josh Reuther, an archaeologist with the University of Alaska Museum of the North.

Researchers regularly present their plans to the Healy Lake Village Council, which represents the Mendas Cha’ag people indigenous to the area, before undertaking studies, including this one. The council also authorized the genetic testing of the study’s new specimens.

Evelynn Combs, a Healy Lake member, grew up in the Tanana Valley, exploring dig sites as a kid and taking in what she learned from archaeologists. She’s known Lanoë, Potter and Reuther since she was a teenager. Now an archaeologist herself, Combs works for the tribe’s cultural preservation office.

“It is little—but it is profound—to get the proper permission and to respect those who live on that land,” Combs said.

Healy Lake members, Combs said, have long considered their dogs to be mystic companions. Today, nearly every resident in her village, she said, is closely bonded to one dog. Combs spent her childhood exploring her village alongside Rosebud, a Labrador retriever mix.

“I really like the idea that, in the record, however long ago, it is a repeatable cultural experience that I have this relationship and this level of love with my dog,” she said.

“I know that throughout history, these relationships have always been present. I really love that we can look at the record and see that, thousands of years ago, we still had our companions.”

‘Ticking time bomb’: Extreme snowfall fuels avalanche danger around Haines

‘Ticking time bomb’: Extreme snowfall fuels avalanche danger around Haines


Avalanche professionals are warning backcountry adventurers to stay out of risky terrain after snow slammed the Upper Lynn Canal in late December.

National Weather Service data shows the storm dumped at least 44 inches of snow in Haines, making it the sixth snowiest five-day period in more than two decades. Other reports documented closer to six or seven feet.

“It was definitely one of the higher snowfalls you’ve gotten in five days, pretty much out of all your time that the station’s been there,” said Juneau-based meteorologist Edward Liske.

The dumping has created a risky situation in the backcountry that warrants extreme caution, said Jeff Moskowitz, the director of the Haines Avalanche Center.

His main message: “Avoid being in or around avalanche terrain.”

Earlier this week, Moskowitz dug a snow pit in town – in front of Haines’ historic Fort Seward – that confirmed his assessment. Standing chest-deep in the pit, he pointed out layers of snow stacked on top of each other, each representing a different storm.

There was a somewhat fluffy layer on top, from the snowfall in early January. Below that, there was a roughly three-foot-deep layer that was more compact, from the late December storm.

And then there was a thin, feeble layer of snow just inches from the ground that crumbled like sugar when Moskowitz ran his hand through it. That snow was on the ground before the big storm – it’s the layer that could collapse and trigger an avalanche under the weight of more precipitation, snowmachines or humans.

“We have about a meter of really strong snow just sitting over this sugar,” Moskowitz said, calling it a “dangerous combination for avalanches.”

Starting Dec. 27, the situation prompted the center to issue warnings about high avalanche risk in the Haines area. Moskowitz said people should stay off slopes that are greater than 30 degrees – and avoid traveling beneath them.

“It’s just a tricky situation, because there’s lots of snow, and we want to go play,” he said. “But we still have this strong-over-weak layering in most places.”

In some places, he said, the weak layer may be buried so deep that a human or snowmachine wouldn’t trigger it. But in shallower areas, like near trees or rocks. the layer would be closer to the surface and more likely to trigger an avalanche.

“People could ride that slope numerous times until one person finds that weak spot,” he said.

The deluge has stopped for now. But the situation could get worse before it gets better, as temperatures rise and the top layer of snow consolidates into a heavier, thicker slab. New precipitation or other conditions could trigger a natural avalanche cycle, wiping that weak layer out.

“Otherwise, it’s a little bit like a ticking time bomb,” Moskowitz said.

Haines Avalanche Center

The Haines Avalanche Center is a nonprofit and the main source of avalanche information in the Chilkat Valley, which draws backcountry adventurers from around the world. Moskowitz emphasized the importance of donations, grants and borough funding to make that work possible.

In the past, the Haines Borough has asked nonprofits to apply for funding from a $100,000 bucket. But Haines Mayor Tom Morphet said that, amid a steep budget deficit, the assembly discontinued that grant process for fiscal year 2026, which runs through June.

That has meant less funding than usual for the Avalanche Center, which has just three part-time employees, including Moskowitz.

“Less funding means less staff time,” Moskowitz said. “And staff time means that locals who are avalanche professionals and have certifications are out there, digging in the snow, making assessments, posting that information publicly.”

The center posts a general avalanche information product every week, plus a weather forecast and season summary. They also issue advisories when avalanche danger is high, including three days in a row in late December.

But the center does not currently have the funding or staff capacity to consistently publish advisories when avalanche risk is low, moderate or considerable.

“What we don’t want, is that there’s an accident that sparks the public interest in supporting the Avalanche Center,” Moskowitz said. “We just need to maintain the services we provide and just keep it going year after year after year.”

Morphet, the mayor, said the borough and assembly are “acutely aware” of the center’s importance.

Moskowitz said people who recreate in the backcountry can help by paying close attention to their surroundings – and he urged them to send in their observations online.

That could mean details about a human-triggered or natural avalanche, about where the sun has hit the mountains on a particular day, or an observation that feathery crystals – known as surface hoar – have started forming on the snow’s surface.

“There’s very little information that we’re not going to find useful,” Moskowitz said. “All of that is very valuable, and it helps to inform this bigger picture.”

Alaska delegation mixed on Venezuela capture legality, day before presidential war powers vote

Alaska delegation mixed on Venezuela capture legality, day before presidential war powers vote


ANCHORAGE, Alaska (KTUU) – Alaska’s congressional delegation had mixed reactions Wednesday on the legality of the Trump administration’s actions in Venezuela over the weekend, just a day before they’re set to vote on a bill ending “hostilities” in Venezuela.

It comes days after former Venezuelan Nicolás Maduro was captured by American forces and brought to the United States in handcuffs to face federal drug trafficking charges.

All U.S. Senators were to be briefed by the administration members at 10 a.m. ET Wednesday, including Secretary of State Marco Rubio and Secretary of Defense Pete Hegseth, according to CBS News.

Spokespersons for Alaska Sens. Lisa Murkowski, R-Alaska, and Dan Sullivan, R-Alaska, say they were at that meeting, but from their responses, the two shared different takeaways.

Sullivan, who previously commended the Trump administration for the operation in Venezuela, told KDLL after his briefing that the next steps in Venezuela would be done in three phases.

“One is just stabilization. They don’t want chaos,” he said.

“The second is to have an economic recovery phase … and then finally, the third phase is a transition to conduct free and fair elections and perhaps install the real winner of the 2024 election there, which was not Maduro.”

Murkowski spokesperson Joe Plesha said she had similar takeaways to Sullivan on the ousting of Maduro, but still held concerns on the legality.

“Nicolás Maduro is a dictator who led a brutally oppressive regime, and Venezuela and the world are better places without him in power,” Plesha said in a statement Wednesday. “While [Murkowski] continues to question the legal and policy framework that led to the military operation, the bigger question now is what happens next.”

Thursday, the Senate will decide what happens next when they vote on a war powers resolution which would require congressional approval to “be engaged in hostilities within or against Venezuela,” and directs the president to terminate the use of armed forces against Venezuela, “unless explicitly authorized by a declaration of war or specific authorization for use of military force.”

Several House leaders have also received a briefing from the administration according to CBS News. A spokesperson for Rep. Nick Begich, R-Alaska, said he received a House briefing and left believing the actions taken by the administration were legal.

“The information provided in today’s classified House briefing further confirmed that the actions taken by the Administration to obtain Maduro were necessary, time-dependent, and justified; and I applaud our military and the intelligence community for their exceptional work in executing this operation,” Begich said in a statement.

Looming vote

Sen. Tim Kaine, D-VA, authored the war powers resolution scheduled for debate Thursday at 11 a.m. ET — 7 a.m. AKST.

It’s a resolution which was one of the biggest topics of discussion on the chamber floors Wednesday.

Sen. Rand Paul, R-KY, said on the Senate floor Wednesdya that the actions taken by the administration were an “act of war,” and the president’s capture of Maduro violated the checks and balances established in the constitution, ending his remarks by encouraging his colleagues to vote in favor of the resolution.

“The constitution is clear,” Paul said. “Only Congress can declare a war.”

If all Democrats and independents vote for the Kaine resolution, and Paul keeps to his support, the bill will need three more votes to pass. If there is a tie, the vice president is the deciding vote.

“It’s as if a magical dust of soma has descended through the ventilation systems of congressional office buildings,” Paul continued Wednesday, referring to a particular type of muscle relaxant.

“Vague faces in permanent smiles and obedient applause indicate the degree that the majority party has lost its grip and have become eunuchs in the thrall of presidential domination.”

Legality of actions under scrutiny

U.S. forces arrested Maduro and his wife, Cilia Flores, from their Caracas home in an overnight operation early Saturday morning, Alaska time. Strikes accompanying the capture killed about 75 people, including military personnel and civilians, according to U.S. government officials granted anonymity by The Washington Post.

Maduro pleaded not guilty Monday in a New York courtroom to drug trafficking charges that include leading the “Cartel of the Suns,” a narco-trafficking organization comprised of high-ranking Venezuelan officials. The U.S. offered a $50 million reward for information leading to his capture.

Whether the U.S. was legally able to capture Maduro under both domestic and international law has been scrutinized in the halls of Congress. Members of the administration, like Secretary of State Marco Rubio, have been open in defending what they say was a law enforcement operation carrying out an arrest warrant, The Hill reports. Lawmakers, like Paul or Sen. Chuck Schumer, D-NY, say the actions were an act of war and a violation of the constitution.

While the president controls the military as commander in chief, Congress constitutionally has the power to declare wars. Congressional Democrats have accused Trump of skirting the Constitution by not seeking congressional authorization before the operation.

Murkowski has not outright condemned or supported the actions taken by the administration, saying in a statement she was hopeful the world was safer without Maduro in power, but the way the operation was handled is “important.”

Sullivan, on the other hand, commended Trump and those involved in the operation for forcing Maduro to “face American justice,” in an online statement.

Begich spokesperson Silver Prout told Alaska’s News Source Monday the Congressman believed the operation was “a lawful execution of a valid U.S. arrest warrant on longstanding criminal charges against Nicolás Maduro.”

The legality of U.S. military actions against Venezuela has taken significant focus in Washington over the past several months, highlighted by a “double-tap” strike — a second attack on the same target after an initial strike — which the Washington Post reported killed people clinging to the wreckage of a vessel after the military already struck it. The White House has confirmed the follow-up attack.

Sullivan, who saw classified video of the strike, previously told Alaska’s News Source in December he believed actions taken by the U.S. did not violate international law.

“I support them doing it, but they have to get it right,” he said. “I think so far they’re getting it right.”

Murkowski, who has not seen the video, previously said at an Anchorage press event the takeaways on that strike’s legality seem to be divided along party lines.

“I spoke to a colleague who is on the Intelligence Committee, a Republican, and I spoke to a colleague, a Democrat, who is on the Senate Armed Services Committee … their recollection or their retelling of what they saw [was] vastly different.”
