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.

Alaska Senate committee advances draft capital budget, boosting funds for school maintenance

Alaska Senate committee advances draft capital budget, boosting funds for school maintenance


The Alaska Senate Finance committee advanced a draft capital budget on Tuesday that would put nearly $250 million toward state facilities and maintenance projects next year.

The draft budget adds $88 million to Gov. Mike Dunleavy’s proposed capital budget of $159 million, with the largest additions going toward K-12 schools and university facilities maintenance.

That was a focused effort by the finance committee, said co-chair Sen. Bert Stedman, R-Sitka, who called funding for education facilities maintenance a “heavy concentration” on Wednesday.

Earlier this year, students and school officials testified to lawmakers that decades of deferred maintenance has reached crisis levels — with many rural school districts in particular grappling with deteriorating facilities, failing water and sewer systems — which they say is degrading student and staff morale. Lawmakers have expressed support and increased funding in recent years, but point to Gov. Mike Dunleavy’s history of vetoes as a roadblock for funding education.

The Senate draft includes $57.8 million in additional funding toward K-12 school maintenance through the Alaska Department of Education and Early Development and $17 million toward the University of Alaska. It also includes $5.7 million for the Alaska Court System’s facilities and $8 million for community infrastructure and workforce development programs through the Alaska Department of Commerce, Community, and Economic Development.

The Legislature relies on state ranked lists to prioritize where to direct funding to capital projects for K-12 schools, the university system and the court system.

For K-12 schools, the state’s current major maintenance list totals over $400 million needed for 103 school projects and repairs. Stedman said he recognized this year’s capital budget will only fund a fraction of those.

“Hopefully we get a quarter of it done, or something like that, but it’d be nice to retire the entire list,” Stedman said.

The draft budget would fund the top 15 school projects on the list, plus funds for three other schools in need of emergency fuel tank repairs. The top projects range from roof and boiler replacements to septic systems, fire suppression and safety upgrades in schools from Fairbanks to the Aleutian Islands.

In order to distribute funds more widely, members of the finance committee reduced funding for one project in Galena, in the Western Interior of Alaska, from roughly $35 million to $5 million for renovations to the Sydney C. Huntington Elementary and High Schools. They also allocated $17 million towards rebuilding the school in Stebbins in Western Alaska, after it burned down in 2024.

The Senate draft also adds nearly $14 million in funding for the state-run Mt. Edgecumbe High School, which has been the focus of public attention and concern after a quarter of students disenrolled this year. The additional facilities dollars include $10 million to remodel the dining hall, $3.1 million to replace dorm windows, $460,000 to replace dorm furniture, $50,000 to replace mattresses and $125,000 to replace aging laundry machines.

Finance members added $17 million to fund the top nine projects across the University of Alaska system — three projects each within the three major campuses.

Sen. Jesse Kiehl, D-Juneau, serves on the finance committee and his district includes University of Alaska Southeast. He described the proposed funds as a “nickel” compared to the “colossal” deferred maintenance needs of the university system.

“That’s been built by Legislatures and Boards of Regents for 40 years,” he said on Wednesday, adding that it is a shared responsibility to put funding towards repairs and upgrades.

“The Constitution makes them a separate body within the executive branch that puts a lot of responsibility on them, too, more than the general state government,” he said “So university major maintenance is its own huge problem.”

The draft budget also includes $5.7 million for upgrades to state court facilities, mostly targeted to Anchorage and Sitka. It contains nearly $10 million for workforce development programs geared at the construction and oil and gas sectors, including for the Fairbanks Pipeline Training Center and Alaska Vocational Technical Center in Seward.

An amendment to add $25 million to the draft budget for the Port of Anchorage, sponsored by Sen. Kelly Merrick, R-Eagle River, was voted down on Tuesday by a 5 to 2 vote.

Before voting against the proposal, finance co-chair Sen. Lyman Hoffman, D-Bethel, said during committee deliberations the priority this year is to fund as many school maintenance projects on the list as possible, saying “schools are falling apart” and must be maintained to prevent further deterioration.

“Students that are trying to learn deserve better,” Hoffman said. “And if we are not able to provide this major maintenance, we are going to see these schools continue to crumble, and the financial burden to the state of Alaska will be hundreds of millions of dollars to rebuild schools.”

More funding for school maintenance and other capital projects could be added by the Alaska House of Representatives, who will take up the draft budget bill after it’s approved by the Senate in the coming weeks.

Bear injures two US soldiers during military training in Alaska | The Jerusalem Post


Two US soldiers were wounded by a brown bear during a training exercise in Alaska on Thursday, the US Army stated.

Anchorage Daily News reported that the soldiers were from the 11th Airborne Division, and that the exercise had been a “land navigation training event” near Joint Base Elmendorf-Richardson.

State wildlife officials said that the bear attack seemed to be a defensive one, from a bear which had recently emerged from its den. Staff members from the Alaska Department of Fish and Game collected evidence at the scene in an attempt to learn more about the bear, such as its species and gender.

“The incident is currently under investigation, and we are working closely with installation authorities and local wildlife officials to gather all relevant information and ensure the safety of all personnel in the area,” the 11th Airborne Division said in a statement, reported ABC News.

ABC News also cited an 11th Airborne Division spokesperson, Lt.-Col. Jo Nederhoed, who said that the two soldiers had been seriously wounded, but were receiving care at a hospital in Anchorage, and had shown improvement by Saturday morning.

“We hope both individuals have a full and quick recovery, and our thoughts are with them during this time,” Fish and Game Regional Supervisor Cyndi Wardlow said in a statement reported by Anchorage Daily News. “In this case, having bear spray with them in the field may have saved their lives.” 

Both of the soldiers reportedly had and used bear spray during the attack.

The bear’s condition and whereabouts are currently unknown.

Travel prices are going up, up and away. Here’s what to watch.

Travel prices are going up, up and away. Here’s what to watch.


Up, up and away … that’s where most travel prices are going.

It’s true. Not only are our nation’s geopolitical thrusts in the Mideast affecting the cost of your fill-ups, every component of your trip from airfares to car rentals and hotel stays are subject to price hikes.

Imagine filling up a jetliner with jet fuel that’s doubled in price. It’s enough to melt your credit card, regardless of the number of points you get for every dollar spent!

Because the price of oil affects everything, higher prices are eating away at your travel budget in many ways.

Bag fees

There’s lots of press on this. All airlines are increasing their checked-bag fees because of the jump in fuel prices.

Back in 2009, Alaska Airlines instituted a $15 fee for the first checked bag and $25 for the second bag. At the time, there was no charge for the first bag and a second bag was $25.

Last week, Alaska Airlines, along with other major airlines, increased its fees to $45 for the first checked bag and $55 for the second bag. Delta Air Lines charges the same.

Even if the cost of oil comes down, I don’t expect bag fees will ever be reduced.

Travelers who live in Alaska are somewhat insulated from the new hikes because both Delta and Alaska Airlines offer two free checked bags, with conditions:

Advertisement

1. Alaska offers two free checked bags for travelers flying to or from Alaska who are enrolled in Club 49. This does not affect other flights on Alaska. Separately, ATMOS credit card holders can get a free checked bag. Also, elite members of the ATMOS scheme get one or two free checked bags systemwide.

2. Delta offers two free checked bags for travelers flying to or from Alaska who are SkyMiles members who live in Alaska. Again, this does not apply to other Delta flights. Separately, Delta American Express cardholders can get a free checked bag.

3. Elite-level travelers with the oneworld airline cartel, including Alaska Airlines, can get one or two checked bags on American, British Airways, Japan Airlines, Qantas or other oneworld carriers.

Main Cabin vs. Basic Economy

The spread between the lowest available price, Basic Economy, and a more flexible ticket, Main Cabin, has increased. While the difference used to be $20-$30 each way when the Basic Economy scheme was introduced in 2018, the round-trip upcharge now can exceed $100.

Advertisement

For example, the lowest Basic fare to Portland is $337 round-trip on Alaska Airlines. The upcharge to Main Cabin, with full loyalty points, pre-assigned seats and more flexibility on changes and cancellations, is $447, a 33% upcharge.

This trend is not specifically attributable to the new Iran War. It’s just a cost that continues to rise.

New fees

I’m impressed at the creativity of airline people who dream up new fees. Here are some of my favorites from Alaska Airlines:

1. Phone reservations: $15

2. Partner award booking fee: $12.50

Advertisement

3. Pet travel fee: $100 in the cabin, $200 in the baggage compartment with a kennel

4. Left on board item return fee: $20

On Condor Airlines, operating the only nonstop service from Anchorage to Europe, travelers can choose from four different bundles in economy class. The least-expensive, Economy Zero, from $840 round-trip, features fees for travelers:

1. Carry-on bag fee, up to 8kg: $35; a small bag like a purse always is included for free

2. Checked bag: $75

Advertisement

3. Airport check-in: $30

All three of these fees are included in the next-highest fare bucket, Economy Classic, from $900 round-trip. It’s cheaper to buy the bundle than it is to buy the components a la carte. Seat assignments are additional, from $25 for economy.

Airfares on the rise

There are a few good deals available for travel to select West Coast/Intermountain destinations in May, including:

1. Anchorage-San Francisco on Alaska Airlines, from $307 round-trip. Fly May 15-28 only. Add $90 round-trip for Main cabin.

2. Anchorage-Los Angeles on Alaska Airlines, from $317 round-trip. May 15-25 only. Add $90 round-trip for Main.

Advertisement

3. Anchorage-Phoenix on United, Delta or Alaska, from $267-$287 round-trip. Fly May 8-June 9 only. Add $90-$100 for Main.

4. Anchorage-Denver $357 round-trip on Delta. Fly May 8-June 9 only. Add $90 round-trip for Main.

For travel to other destinations, or later in the summer, be prepared to pay more.

Flying to Hawaii? Alaska Air’s nonstop prices out at $706 round-trip between May 30 and June 6. Add $110 round-trip for Main.

Nonstop flights from Anchorage to Salt Lake City start at $669 round-trip with Delta on May 17. That’s $100 more than the cost for the same flights last month. Add $90 more for Main.

Hotel costs continue to rise, accompanied by pesky resort fees.

The Outrigger on the Beach in Waikiki is a very nice beachfront hotel. It’s not plush, or the nicest property. But it’s solid. The cost is $334 per night.

But there’s more: a $50 per night resort fee, plus a variety of taxes and charges, totaling $112.55 per night.

Down in Seattle, the Sound Hotel in the Belltown neighborhood is marketed by Hilton. The discounted rate for “Honors” members — it’s free to join — is $313.34 per night for a king room in late May. Taxes and fees add an extra $56.40 per night.

There’s no appreciable bump yet for hotel rates as a result of the oil price surge. Yet. But if these hotel rates seem high, they’re in line with hotel rates in Anchorage this summer. At the Sheraton in Anchorage in June, it’s $450 per night, plus $54 in taxes and fees, when booked at Expedia.

Car rentals are not cheap

My go-to site for car rentals is the Costco site, which compares major brands and automatically includes Costco discounts.

In Las Vegas, for a one-day rental in May, Budget charges $67 per day, which includes taxes and fees of $22.77. In Anchorage, the same kind of car, medium SUV, costs $92.97 with Alamo.

The biggest differences so far in car rental rates seems to be the bill you’ll pay when you fill up the tank before returning. There’s no appreciable jump in prices because of the new war.

When it comes to making travel arrangements for the spring and summer, it’s more risky making completely non-refundable arrangements.

I made the decision to purchase most of my summer travel plans in advance, but only after determining I would not need to change the dates. Particularly with airline tickets, it’s expensive to change your dates.

There’s lots of uncertainty regarding travel arrangements, particularly international travel. As fuel prices go up due to oil shortages, travel companies will look for ways to recoup the increased costs. In most cases, those higher costs will be borne by travelers.
