Geologist explains science of landslides in Southeast Alaska
KETCHIKAN, Alaska (KTUU) – Geologists with the State of Alaska are currently in Ketchikan researching slope conditions in an effort to ensure the area is safe before looking into the actual cause of Sunday’s deadly landslide.
“When talking about this, it’s really difficult to imagine what the residents are going through, and our thoughts are really with the families impacted by the recent landslide,” Dr. Gabriel Wolken, the manager of the climate and hazards program with the Alaska division of geological and geophysical surveys, said on Wednesday.
Wolken is also a research professor at the University of Alaska Fairbanks.
“[Geologists are] making sure that the area is safe for the responders and the people trying to put their lives back together. And then soon after this, we will thoroughly analyze the information and the data that are being collected by the geoscientists on the ground, and come up with some causal mechanisms for this event.”
While not sure of the root cause of the landslide — which claimed the life of 42-year-old Sean Griffin — Wolken says that landslides are nearly impossible to predict.
Wolken said geoscientists are gaining a better understanding of what conditions need to be present in order for landslides to occur.
“One thing that is certain is that extreme weather can play a large role in how landslides develop, and intense, prolonged rainfall can play a really large role in this. It can weaken the stability of the slopes,” Wolken said. “This is especially true if the slope’s already saturated, [rainfall] can change the condition of the soil, causing the pore pressure in the soil to increase, which really weakens the stability of the slope. So whenever there’s a lot of rain, a lot of extreme weather, then that can be problematic.”
Wolken says there are warning signs that a landslide is imminent, particularly in Southeast Alaska, where people can keep an eye out for springs in the soil.
That, he says, is an indication the soil is quite saturated. New cracks in the ground or unusual bulges are something to watch out for as well.
“Another thing to keep a lookout for is any precursor indications that movement is occurring, perhaps in a creep fashion,” Wolken explained. “So if you’re in your house, you might notice that there’s cracks that have developed in the drywall or plaster — if you have that in your house — or maybe the door is not closing properly.
“These are all indications that things are kind of changing in the structure of the house, and those are things to look out for in the event that a slow creep might be occurring on the slope.”
Wolken is leading a study on landslide hazards in Haines, 364 miles northwest of Ketchikan. The project is analyzing data from the spring of 2021, taken one year after a deadly landslide claimed two lives.
“There have been too many destructive and deadly events, resulting in 12 fatalities in the last decade,” he said. “So determining whether landslides in Southeast Alaska are occurring more frequently in recent years than in the past is very difficult, if not impossible, to answer at this time.”
He says it’s difficult to determine if landslides are happening more frequently because of a lack of data, as well as inconsistencies in landslide reporting. He explained that the research in Haines is ongoing and reports are currently being prepped.
That’s the work that’s happening now. Scientists and geologists are collecting data that will provide future generations with a better understanding of why these landslides occur.
“Our work is really aimed at generating the actionable science that is needed to improve decision-making across the state, across multiple sectors of society,” Wolken said. “And this doesn’t stop at one landslide. This doesn’t stop at one location of the state.
“So we’re really focused broadly on a statewide landslide hazard preparedness, which means that we’re focused on lots of different places at a single time to try to understand, characterize and assess these different places.”
The work now is happening in Ketchikan, as people like geologist Martin “Mort” Larson are collecting data.
“They’re very busy on the ground, going to different places in the high elevation terrain, looking for different signatures on the landscape that would indicate unstable slope conditions, and that can vary across the board, but certainly looking at saturated ground issues, any scarps that are on the landscape, and doing some preliminary mapping of the area,” Wolken said. “We have deployed personnel to the area to work with our partners from both state and federal agencies. I know that the Department of Transportation is collecting some airborne drone-based remote sensing that’s helping with the folks on the ground in a rapid response sort of way, we have deployed a remote sensing specialist to go down and collect some broader Lidar of the area so that we can use that in our analysis.”

Sand Point teen found 3 days after going missing in lake
SAND POINT, Alaska (KTUU) – A teenage boy who was last seen Monday when the canoe he was in tipped over has been found by a dive team in a lake near Sand Point, according to a person familiar with the situation.
Alaska’s News Source confirmed with the person, who is close to the search efforts, that the dive team found 15-year-old Kaipo Kaminanga deceased Thursday in Red Cove Lake, located a short drive from the town of Sand Point on the Aleutian Island chain.
Kaminanga was last seen canoeing with three other friends on Monday when the boat tipped over.
A search and rescue operation ensued shortly after.
Alaska Dive Search Rescue and Recovery Team posted on Facebook Thursday night that they were able to “locate and recover” Kaminanga at around 5 p.m. Thursday.
“We are glad we could bring closure to his family, friends and community,” the post said.
This is a breaking news story and will be updated when more details become available.

Opinion: Homework for Alaska: Sales tax or income tax?
This is a tax tutorial for gubernatorial candidates, for legislators who will report to work next year and for the Alaska public.
Think of it as homework, with more than eight months to complete the assignment that is not due until the November election. The homework is intended to inform, not settle the debate over a state sales tax or state income tax — or neither, which is the preferred option for many Alaskans.
But for those Alaskans willing to consider a tax as a personal responsibility to help fund schools, roads, public safety, child care, state troopers, prisons, foster care and everything else necessary for healthy and productive lives, someday they will need to decide on a state income tax or a state sales tax after they accept the checkbook reality that oil and Permanent Fund earnings are not enough.
This homework assignment is intended to get people thinking with facts, not emotions. Electing the right candidates will be the first test.
Alaskans have until the next election because nothing will change this year. It will take a new political alignment led by a reality-based governor to organize support in the Legislature and among the public.
But next year, maybe, with the right elected leadership, Alaskans can debate a state sales tax or personal income tax. Plus, of course, corporate taxes and oil production taxes, but those are for another school day.
One of the biggest arguments in favor of a state sales tax is that visitors would pay it. Yes, they would, but not as much as many Alaskans think.
Air travel is exempt from sales taxes. So are cruise ship tickets. That’s federal law, which means much of what tourists spend on their Alaska vacation is beyond the reach of a state sales tax.
Cutting further into potential revenues, state and federal law exempts flightseeing tours from sales tax, which is a particularly costly exemption when you think about how much visitors spend on airplane and helicopter tours.
That leaves sales tax supporters collecting from tourists on T-shirts, gifts for grandchildren, artwork, postcards, hotels, Airbnb, car rentals and restaurant meals. Still a substantial take for taxes, but far short of total tourism spending.
An argument against a state sales tax is that more than 100 cities and boroughs already depend on local sales taxes to pay for schools and other public services. Try to imagine what a state tax piled on top of a local tax would do to kill shopping in Homer, already at 7.85%, or Kodiak, Wrangell and Cordova, all at 7%, and all the other municipalities.
Supporters of an income tax say it would share the responsibility burden with nonresidents who earn income in Alaska and then return home to spend their money.
Almost one in four workers in Alaska in 2024 were nonresidents, as reported by the state Department of Labor in January. That doesn’t include federal employees, active-duty military or self-employed people.
Nonresidents earned roughly $3.8 billion, or about 17% of every dollar covered in the report.
However, many of those nonresident workers are lower-wage and seasonal, employed in the seafood processing and tourism industries, unlikely to pay much in income taxes. But a tax could be structured so that they pay something, which is fair.
Meanwhile, higher-wage workers in oil and gas, mining, construction and airlines (freight and passenger service) would pay taxes on their income earned in Alaska, which also is fair.
It comes down to what would direct more of the tax burden to nonresidents: a tax on income or on visitor spending. Wages or wasabi-crusted salmon dinners.

Nome brothers summit Mt. Kilimanjaro, carry Alaska flag to third major peak
ANCHORAGE, Alaska (KTUU) – Two brothers from Nome recently stood at the summit of Mount Kilimanjaro in Africa, planting an Alaska flag at 19,000 feet above the African plains.
The Hoogendorns completed the seven-day climb — five and a half days up and a day and a half down — trekking through rainforest, desert, and alpine terrain before reaching snow near the summit. The climb marks their third of the world’s seven summits.
Night hike to the top
The brothers began their final summit push at midnight, hiking through the night to reach the top by dawn.
“It was almost like a dream,” Oliver said. “Because we hiked through the night. We started the summit hike at midnight when you’re supposed to be sleeping. So, it was kind of like, not mind boggling, but disorienting. Because you’re hiking all night, but then you get to the top and you can finally see. It’s totally different from what you’d expect.”
At the summit, temperatures hovered around 10 degrees — a familiar range for the Nome brothers. Their guides repeatedly urged them to put on jackets, but the brothers declined.
“We got to the crater, and it was dark out and then it started getting brighter out,” Wilson said. “And then you could slowly see the crater like illuminating and it’s huge. It’s like 3 miles across or something. Like you could fly a plane down on the crater and be circles if you want to. Really dramatic view.”
A team of 17 for two climbers
Unlike their previous expeditions, the brothers were supported by a crew of 17 — including porters, a cook, guides, a summit assistant, and a tent setup crew.
The experience deviated from their earlier climbs, where they carried their own food, melted snow for water, and navigated routes independently.
“I felt spoiled,” Wilson said. “I was like, man, the next mountain’s gonna be kind of hard after being spoiled.”
Alaska flag on every summit
Oliver carried the same full-size Alaska flag on all three of his major summits, including in South America and Denali in North America, despite the added weight in his pack.
“I take it everywhere these days,” Oliver said. “It’s always cool to bring it out. And then people ask, you know, ‘where’s that flag from?’ Say Alaska.”
When asked about his motivation for the expeditions, Wilson said “I guess to like inspire other people. Because it seems like a lot of people think they can’t do something, but if you just try it, you probably won’t do good the first time, but second time you’ll do better. Because you just got to try it out. Believe in yourself.”
Background and next goals
The Hoogendorns won the reality competition series “Race to Survive: Alaska” in 2023. In 2019, they were the first to climb Mount McKinley and ski down that season. Oliver also started a biking trip from the tip of South America to Prudhoe Bay with hopes of still completing it.
Kilimanjaro is their third summit. The brothers said they hope to eventually complete all seven summits, with Mount Vinson in Antarctica among the peaks they are considering next… all while taking Alaska with them every step of the way.
