Final report filed on cause of Wrangell’s deadly landslide

State geologists in early February published their final findings on last year’s Wrangell landslide that killed six people. They found that the Nov. 20 slide was caused by excessive amounts of rain in a short period of time – even for a rainforest.

Wrangell’s Island experienced two large landslides the night of Nov. 20. Two smaller ones happened around the same time, but experts don’t know exactly when. One of the big ones took out two homes and damaged several structures along the highway about 11 miles south of town.

Mort Larson is with the state’s landslide hazards program with the Alaska Division of Geological and Geophysical Surveys.  

He said a team of three geologists gathered data for the report on all the slide sites, as well as other areas of concern on the island.

“We went back and forth of how we wanted publish this, get this out to the right hands and make sure we’re presenting this data (it’s a factual data piece) correctly to the people,” Larson said.

Lots of rain – possibly four inches within 24 hours – mixed with wind likely caused Wrangell’s landslides. It’s similar to what caused deadly landslides in Haines and Sitka in recent years. 

“Slopes get oversaturated and you got more rain systems coming in,” Larson said. “That’s usually one of the key triggers that really kind of get these things moving and that’s what we’ve seen there in Haines, that’s what we saw in Sitka.”

Microclimates and landslide complexities

There’s a complexity on landslide nomenclature and science. A couple examples of other landslides can be deep seated rotational landslides, where the debris goes into the bedrock and rotates the whole block. There’s also translational landslides, which happens when the debris moves along a planar, or flatter surface on a slope, with little rotation.

Those particular slides are known as debris-flow because they were shallow landslides. 

The National Weather Service in Juneau recorded normal amounts of precipitation before the fatal slide, except for the last six hours. In the 24-hour period preceding the landslide, 2.23 inches of rain were recorded at the Wrangell airport. Just over an inch of that happened in the last six hours before the slide. 

“It’s hard to really predict”

Interestingly, during the same 24-hour timeframe, Petersburg, about 30 miles to the northwest, received more than four inches of rain. So why did Petersburg not experience a landslide that night?

It could be because of microclimates, or small pockets of weather, happening within a weather system. That means that there could be different amounts of rain happening in different areas of the same island. 

“In Petersburg, the geology is a little bit different,” Larson said. “The slopes are different, right? The surrounding community in Petersburg, their slopes are a little more gentle. It’s hard to really predict exactly what’s going to really kind of trigger those off. Have those slopes in Petersburg not been as saturated as much as the ones they’re in Wrangell? We don’t know.”

Although Petersburg didn’t experience a landslide that fateful November night, Prince of Wales Island southwest of Wrangell and Petersburg, had many.

The weather service gathers data, like rainfall, from the same spots throughout the region – often at community airports. But the weather in the nearby mountains could be much different.  The rainfall recorded in Wrangell was at the airport, which is on flat ground, ground about 12 miles away from the slide area.

After Wrangell’s slides, the state Department of Transportation installed a rain gauge near the slide site. 

Geologists noticed that the gauge measured up to twice the amount of rain that was recorded at the airport. This could mean that more than four inches of rain may have fallen during the 24 hours preceding the landslide events.

Landslide details

The report shows that at least two landslides occurred during the night of Nov. 20. The largest at mile point 11.2, which was approximately 3,750 feet long – from the head scarp to the shoreline. That’s close to three quarters of a mile. An additional 500 feet stretched into the Zimovia Strait – about half a cruise ship long. It had a width that began at 100 feet and ended at 350 feet.

Scientists also found that two smaller landslides occurred just south of Mile 11.2, based on LiDar (Light Detection and Ranging) monitoring.

All of the landslides consisted of minimal rock material, saturated soils and large wood debris. The LiDar monitoring showed that three of them released more material than what they deposited at their ends. This is common for landslides that end up in the water. Only one landslide, the one at Mile 11.2, deposited in the water though.

The report states that the “volume may have been lost as a thin layer of mud spread across the ground.” There are many gullies that the vegetation could have ended up in as well for one of the slides.

Just one had the same amount of erosion to deposition, which is more common with landslides. Basically, the amount lost at the starting point of a slide and along its route is most likely to end up at the end of the slide.

The Middle Ridge Road landslide, which also occurred on Nov. 20, was close to 150 feet wide (about nine parking spaces) and covered roughly 600 feet of the road. It stretched 3,600 feet long.

Additionally, the geologists found sand and sediment deposits along a channel and powerline above the Nugget Trailer Court at mile point three. A previous landslide deposited rocks and sediment along this area in 2021 or 2022. 

The report states that multiple stream channels (potentially from the previous landslide) directed the water flow to the trailer park following the heavy rains on Nov. 20.

“Our climate is changing”

Plans are in the works for better landslide monitoring for Wrangell. Since the slide, the state has been using remote sensing known as LIDAR to better understand the geography of the island. DGGS and the community is looking for federal funds for a landslide hazard program. Larson said then the local City and Borough, along with the the state’s Division of Geological and Geophysical Surveys, could collaborate on creating two maps – a landslide susceptibility map and a landslide inventory map

“The great piece about that and where we can jump ahead on that is that we just had recently LiDar collected for the entire island,” he said. “That is a key piece for doing these maps. You can’t do them with that if we didn’t have LiDAR, we’d have to go seek funding to get LiDar.”

If approved, they would receive the funds in September and map out parts of the island.

Southeast islands are covered in forested steep mountains. Larson said that he’s seen a pattern with these landslides in the region over the last eight years. He said with the steep slopes and the shallow soil that sits on them, they’re likely to continue. 

Deadly Wrangell landslide is part of a pattern in vulnerable Alaska mountainous terrain

“Our climate is changing,” he said. “We’re getting these big moisture patterns that are coming in these atmospheric river systems that just pummeled Southeast. So they’re going to continue. These are not going to stop and based on the terrain and the geology that we live here in Southeast, a lot of these communities are up against steep terrain, and ocean and water on the other side.”

He said their goal is to evaluate and understand where landslides occur, collect the data, map it out and give the information to decision makers and communities.

252 landslides on Wrangell Island alone

Wrangell’s interim borough manager, Mason Villarma, said he appreciates the help from the state’s Department of Natural Resources and its geology team. 

“It took a lot of time to draft the report,” Villarma said. “We’re really lucky to have the relationship we do with DNR. It’s just the objective facts and circumstances around the conditions that were present pre and post slide that are most interesting.”

Landslides have been happening throughout Southeast Alaska for thousands of years. Between 1998 and 2010, the U.S. Forest Service mapped landslides within the Tongass National Forest. Researchers found 252 landslides – or debris flows – just on Wrangell Island alone.

Those facts don’t make them any less devastating when one happens in your backyard.

Legislative task force offers possible actions to rescue troubled Alaska seafood industry • Alaska Beacon

Legislative task force offers possible actions to rescue troubled Alaska seafood industry • Alaska Beacon


Alaska lawmakers from fishing-dependent communities say they have ideas for ways to rescue the state’s beleaguered seafood industry, with a series of bills likely to follow.

Members of a legislative task force created last spring now have draft recommendations that range from the international level, where they say marketing of Alaska fish can be much more robust, to the hyper-local level, where projects like shared community cold-storage facilities can cut costs.

The draft was reviewed at a two-day hearing in Anchorage Thursday and Friday of the Joint Legislative Task Force Evaluating Alaska’s Seafood Industry. It will be refined in the coming days, members said.

The bill that created the task force, Senate Concurrent Resolution 10, sets a deadline for a report to the full Legislature of Jan. 21, which is the scheduled first day of the session. However, a final task force report may take a little longer and be submitted as late as Feb. 1, said Senate President Gary Stevens, R-Kodiak, the group’s chair.

The draft is a good start to what is expected to be a session-long process, said Rep. Louise Stutes, R-Kodiak, a task force member.

“We can hit the ground running because we’re got some good solid ideas,” Stutes said in closing comments on Friday. The session can last until May 20 without the Legislature voting to extend it.

Another task force member, Sen. Jesse Bjorkman, R-Nikiski, urged his colleagues to focus on the big picture and the main goals.

“We need to take a look at how we can increase market share for Alaska seafood and how we can increase value. Those two things aren’t easy, but those are the only two things that are going to matter long term. Everything else is just throwing deck chairs off the Titanic,” he said Friday.

Many of the recommended actions on subjects like insurance and allocations, if carried out, are important but incremental, Bjorkman said. “If the ship’s going down, that stuff isn’t going to matter,” he said.

Alaska’s seafood industry is beset by crises in nearly all fishing regions of the state and affecting nearly all species.

Economic forces, heavily influenced by international turmoil and a glut of competing Russian fish dumped on world markets, have depressed prices. Meanwhile, operating costs have risen sharply. Climate change and other environmental factors have triggered crashes in stocks that usually support economically important fisheries; Bering Sea king and snow crab fisheries, for example, were closed for consecutive years because stocks were wiped out after a sustained and severe marine heatwave.

In all, the Alaska seafood industry lost $1.8 billion from 2022 to 2023, according to the National Oceanic and Atmospheric Administration.

Those problems inspired the creation of the task force last spring. The group has been meeting regularly since the summer.

The draft recommendations that have emerged from the task force’s work address marketing, product development, workforce shortages, financing, operating costs, insurance and other aspects of seafood harvesting, processing and sales.

One set of recommendations focuses on fisheries research. These call for more state and federal funding and an easy system for fisheries and environmental scientists from the state, federal government and other entities to share data quickly.

The draft recommends several steps to encourage development of new products and markets for them, including non-traditional products like protein powder, nutritional supplements and fish oil. Mariculture should be expanded, with permitting and financing made easier, according to the draft.

The draft recommendations also propose some changes in the structure of seafood taxes levied on harvesters and processors, along with new tax incentives for companies to invest in modernization, product diversification and sustainability.

Other recommendations are for direct aid to fishery workers and fishing-dependent communities in the form of housing subsidies or even development of housing projects. Shortages of affordable housing have proved to be a major challenge for communities and companies, the draft notes. More investment in worker training — using public-private partnerships — and the creation of tax credits or grants to encourage Alaska-resident hire, are also called for in the draft recommendations.

Expanded duties for ASMI?

The Alaska Seafood Marketing Institute, the state agency that promotes Alaska seafood domestically and internationally, figures large in the draft recommendations.

The draft calls for more emphasis on the quality and sustainability of Alaska fish and, in general, more responsibilities for ASMI. An example is the recommended expansion of ASMI’s duties to include promotion of Alaska mariculture. That would require legislation, such as an early version of bill that was sponsored by outgoing Rep. Dan Ortiz, I-Ketchikan. It would also require mariculture operators’ willingness to pay into the program.

But ASMI, as it is currently configured, is not equipped to tackle such expanded operations, lawmakers said. Even obtaining modest increases in funding for ASMI has proved to be a challenge. A $10 million increase approved by the Legislature last year was vetoed by Gov. Mike Dunleavy, who cited a failure by ASMI to develop a required plan for the money. 

The governor’s proposed budget released in December includes an increase in state money for ASMI, but his suggestion that $10 million in new funding be spread over three years falls far short of what the organization needs, Stevens said at the time.

Incoming House Speaker and task force member Bryce Edgmon, I-Dillingham, said there will probably be a need to reorganize or restructure ASMI to make it more autonomous. That might mean partnering with a third party and the creation of more managerial and financial independence from whoever happens to be in political office at the time, as he explained it.

“The umbilical cord needs to be perhaps cut to some degree,” Edgmon said on Friday, during the hearing’s public comment period. The solution could be to make ASMI more of a private entity, he said.

“Because the world is changing. It’s a global marketplace. We need to have ASMI to have as large a presence as possible,” he said. 

But for now, ASMI and plans for its operations have been constricted by political concerns. “People are afraid of how it’s going to go back to the governor’s office,” Edgmon said.

Federal assistance

U.S. Sen. Lisa Murkowski, R-Alaska, spoke to the task force on Thursday about ways the federal government could help the Alaska seafood industry.

One recent success, she said, is passage of the bipartisan Fishery Improvement to Streamline Untimely Regulatory Hurdles post Emergency Situation Act, known as the FISHES Act, which was signed into law a few days earlier.

The act establishes a system to speed fisheries disaster aid. It can take two to three years after a fisheries disaster is declared for relief funds to reach affected individuals, businesses and communities, and that is “unacceptable,” Murkowski said.  The bill addresses that situation, though not perfectly. “It’s still not the best that it could be,” she said.

Another helpful piece of federal legislation that is pending, she said, is the Working Waterfronts Bill she introduced in February. The bill contains provisions to improve coastal infrastructure, coastal energy systems and workforce development.

More broadly, Murkowski said she and others continue to push for legislation or policies to put seafood and fisheries on the same footing as agriculture. That includes the possibility of fishery disaster insurance similar to the crop insurance that is available to farmers, she said.

But getting federal action on seafood, or even attention to it, can be difficult, she said.

“It is a reality that we have faced, certainly since my time in the senate, that seafood has been viewed as kind of an afterthought by many when it comes to a food resource, a source of protein,” she said.

Inclusion of seafood in even simple programs can be difficult to achieve, she said. She cited the U.S. Department of Agriculture’s decision, announced in April, to include canned salmon as a food eligible for the Special Supplemental Nutrition Program for Women, Infants, and Children, also known as WIC. She and others had been working for several years to win that approval, she said.

Tariffs a looming threat

Seafood can also be an afterthought in federal trade policy, Murkowski said.

Tariffs that President-elect Donald Trump has said he intends to impose on U.S. trade partners pose a serious concern to Alaska’s seafood industry, she said.

“The president-elect has made very, very, very, very clear that this is going to be a new administration and we’re going to use tariffs to our advantage. I don’t know what exactly to expect from that,” she said.

In the past, tariffs imposed by the U.S. government have been answered with retaliatory tariffs that cause problems for seafood and other export-dependent industries.

Jeremy Woodrow, ASMI’s executive director, has similar warnings about tariffs, noting that about 70% of the Alaska seafood, as measured by value, is sold to markets outside of the U.S.

“We tend to be, as an industry, collateral damage in a lot of trade relationships. We’re not the main issue. And that usually is a bad outcome for seafood,” he told the committee on Thursday.

To avoid or mitigate problems, Alaska leaders and the Alaska industry will have to respond quickly and try to educate trade officials about tariff impacts on seafood exports, Woodrow said.

Task force members expressed concerns about impacts to the export-dependent Alaska industry.

“If we raise tariffs on another country, won’t they simply turn around and raise tariffs on us?” asked Stevens.

Tariffs on Chinese products, which Trump has suggested repeatedly, could cause particular problems for Alaska seafood, Stutes said. She pointed to the companies that send fish, after initial processing, to China for further processing in preparation for sale to final markets, some of which are back in the U.S.

“If there is a huge tariff put on products going and coming from China, that would seem to me to have another huge gut shot to those processors that are sending their fish out for processing,” Stutes said.

Bjorkman, a former high school government teacher, said history shows the dangers of aggressive tariff policies.

The isolationist “America-first” approach, as carried out at turns over the past 150 years, “hasn’t worked out very well. It’s been real bad,” Bjorkman said.” As an alternative, he suggested broader seafood promotions, backed by federal or multistate support, to better compete in the international marketplace.

Rural Alaska schools face funding shortfall after U.S. House fails to pass bipartisan bill • Alaska Beacon

Rural Alaska schools face funding shortfall after U.S. House fails to pass bipartisan bill • Alaska Beacon


Rural schools, mostly in Southeast Alaska, are facing a major funding shortfall this year after the U.S. House of Representatives failed to reauthorize a bill aimed at funding communities alongside national forests and lands. 

The bipartisan Secure Rural Schools and Community Self-Determination Act was first passed in 2000, and enacted to assist communities impacted by the declining timber industry. It provided funds for schools, as well as for roads, emergency services and wildfire prevention. The award varies each year depending on federal land use and revenues. The legislation is intended to help communities located near federal forests and lands pay for essential services. In 2023, the law awarded over $250 million nationwide, and over $12.6 million to Alaska.

But this year, the bill passed the Senate, but stalled in the House of Representatives amid partisan negotiations around the stopgap spending bill to keep the government open until March. House Republicans decided not to vote on the bill amid a dispute around health care funding, a spokesperson for the bill’s sponsor, Oregon Sen. Ron Wyden, told the Oregon Capital Chronicle, which first reported the story. 

Eleven boroughs, as well as unincorporated areas, in the Tongass and Chugach national forests have typically received this funding, awarded through local municipalities. According to 2023 U.S. Forest Service data, some of the districts who received the largest awards, and now face that shortfall, include Ketchikan, Wrangell, Petersburg, Sitka and Yakutat, as well as the unincorporated areas.

“We’re already at our bottom,” said Superintendent Carol Pate of the Yakutat School District, which received over $700,000 in funding, one of the largest budget sources for its 81 students. 

“We are already down to one administrator with six certified teachers,” Pate said in a phone interview Thursday. “We have a small CTE (career and technical education) program. We don’t have any art, we don’t have any music. We have limited travel. Anything that we lose means we lose instruction, and our goal is for the success of our students.”

Yakatat is facing a $126,000 deficit this year, a large sum for their $2.3 million budget, Pate said. “So that’s a pretty significant deficit for us. We do our best to be very conservative during the school year to make up that deficit. So wherever we can save money, we do.” 

The school has strong support from the borough, Pate said. However, last year they were forced to cut funding for one teacher and a significant blow for the school, she said.

“We’re trying very hard to break the cycle, but it’s a continuing cycle,” she said. “Every time we lose something, we lose kids because of it, and the more kids we lose, the more programs we lose.”

In the southern Tongass National Forest community of Wrangell, the school district received over $1 million in funds last year, and Superintendent Bill Burr said the federal funding loss is dramatic. 

“It’s pretty devastating from a community standpoint,” Burr said in a phone interview. “Because that is very connected to the amount of local contribution that we get from our local borough, it has a dramatic effect on the school district, so I’m disappointed.”

“As these cuts continue to happen, there’s less and less that we’re able to do,” he said. “School districts are cut pretty much as thin as they can. So when these things happen, with no real explanation, the impact for districts that do receive secure schools funding is even more dramatic.”

Whether and how the funding loss will impact the district has yet to be determined, as budgets for next year are still in development, Burr said, but it could mean cuts to matching state grants, facilities projects, or staff salaries. He said most non-state money for the district comes from the federal program.

“Part of our funding does come from sales tax, but a majority of it comes from the secure rural schools (grant),” he said. “So without increases in other areas, the amount of money that can come to the schools is going to be injured.”

“We do have contracts, and a majority of our money is paid in personnel. So we would have those contracts to fill, regardless of the funding, until the end of the year. A major reduction really will affect our ability to provide school services and personnel, so it could have a massive impact on next year’s, the fiscal ‘26 year, budget,” he said. 

The district is facing an over $500,000 budget deficit this year, Burr said, and so the loss puts further pressure on the district.

“So we’re continuing to find areas that we can cut back but still provide the same service. But that’s getting harder and harder,” he said. 

The schools in unincorporated areas known as regional educational attendance areas, received over $6 million in funding through the program.

Alaska Sens. Lisa Murkowski and Dan Sullivan supported the bill through the Senate.

Murkowski was disappointed that the bill was not reauthorized, a spokesperson for the senator said. 

“As a longtime advocate for this program, she recognizes its critical role in funding schools and essential services in rural communities,” said Joe Plesha, in a text Friday. “She is actively working to ensure its renewal so that states like Alaska are not disadvantaged.”

Former Alaska Rep. Mary Peltola also supported the funding. 

Alaska’s school funding formula is complex, and takes into account the local tax base, municipalities’ ability to fund schools, and other factors. With the loss of funding for the local borough’s portion, whether the Legislature will increase funding on the state’s side is to be determined.

The Department of Education and Early Development did not respond to requests for comment on Friday. 

Superintendents Burr and Pate described hope for the upcoming legislative session, and an increase in per-pupil spending. “The loss of secure rural schools funding makes it even more difficult to continue with the static funding that education in the state has received,” Burr said. 

“I really have high hopes for this legislative season. I think that the people that we’ve elected recognize the need to put funding towards education,” Pate said. 

The funding could be restored, if the legislation is reintroduced and passed by Congress. Both Oregon Democratic Sen. Wyden and Idaho Republican Sen. Mike Crapo have said they support passing the funding this year.
