When travelers visit Alaska, they often want to see glaciers.

And it’s the perfect place for those.  

The Last Frontier is home to the most glaciers in the U.S. There are roughly 27,000 glaciers across the state, covering an area of about 80,000 square kilometers, according to Louis Sass, an Anchorage-based glaciologist with the Alaska Science Center U.S. Geological Survey.  

“That’s about the same amount of area as the state of South Carolina or Lake Superior,” he said. 

That’s huge, yet not as big as it used to be.

“Globally, most glaciers are melting and thinning and retreating much faster now than they were, say, prior to about the year 2000,” Sass said.  

Here’s what that means for travelers hoping to see glaciers in Alaska and elsewhere. 

What causes melting of glaciers? 

It’s natural for glaciers to melt. 

“You can really just think of a glacier as a huge conveyor belt that takes snow and ice from up high, where it can’t melt, down to low elevations where it’s a lot warmer and it does melt.”

It’s the rate of melting and thinning that’s shifted dramatically. 

Research published in July in the peer-reviewed British journal Nature Communications, found the rates of glacier area shrinkage in Alaska’s Juneau icefield were five times faster from 2015 to 2019 than from 1948 to 1979. 

A National Park Service report on Alaska’s glaciers noted glaciers within Alaska national parks shrank 8% between the 1950s and early 2000s and glacier-covered area across the state decreased by 13% between 1985 and 2020.

“These systems are under threat,” said Brice Esplin, Director of Sustainable Tourism and Partnerships at Leave No Trace. “Climate change is affecting them.” 

While Sass did not identify climate change by name, noting he’s not a climate scientist, he said glaciers are very sensitive to inputs like temperature and precipitation. 

“Temperature has kind of a double whammy, because air temperature can change the phase of the precipitation, so more of the precipitation that falls out of the sky can actually be rain instead of snow. And rain tends to run off the glacier and not add to the glacier mass,” he said.  

The U.S. Department of Agriculture’s Northwest Climate Hub notes Alaska is “warming at two to three times the rate of the global average.”

What is happening to the glaciers in Alaska? 

“Some glaciers are advancing, but the vast majority of them are shrinking, and at Kenai Fjords (National Park), you can just see that right up close and personal,” Peter Christian, chief spokesperson for Public Affairs for the National Park Service’s Alaska region, said last year during USA TODAY’s more than yearlong national park series. 

An area of the park where that’s especially pronounced is Exit Glacier. 

“It literally is changing yearly. If you went back from one year to the next, you could see how far the glacier has continued to retreat up into the mountains,” he said, noting that the Park Service has signs set up along the trail to the glacier, marking the changes.

Matanuska Glacier, about 100 miles from Anchorage, is another example.

“It’s only retreated a little bit. It’s actually very close to where it was even 120 years ago, but it has thinned a lot, and it’s actually really easy to see that thinning,” Sass said. “The ice is just sort of deflated as it loses mass and it melts.”

Matanuska Glacier is the state’s largest glacier accessible by road, according to Alaska’s official travel arm, Travel Alaska, but Sass said it used to be even easier to reach. 

“There’s all these sort of little melt puddles right along the edge of the glacier that are getting bigger and bigger and harder to cross, and there’s more and more mud to try to get out to the ice,” he said. “It used to be, on Matanuska Glacier, you basically walked from the parking lot onto clean, white ice.” 

He added that many tidewater glaciers have also been impacted. 

“So even big cruise ships that are trying to take passengers up to see calving glaciers, they have to go further up the inlet to actually be able to see a calving glacier,” he said. “Places that used to have a really good view of a glacier sometimes don’t have a good view anymore, and so it gets generally more and more challenging to get to those places where you can kind of experience the same level of glacier.”

Where can you see a glacier? 

From Wrangell-St. Elias National Park and Preserve, home of the most glaciers of any national park, to Mendenhall Glacier, which is protected by the U.S. Forest Service, there are so many places to see glaciers in Alaska. 

They can also be found in Glacier National Park in Montana, Grand Teton National Park in Wyoming, Mount Rainier National Park in Washington, and elsewhere around the West and the world. 

“It’s important for people to see these amazing natural systems, because they create that appreciation, that love and that connection of nature and for the in the future,” Esplin said.

He encourages travelers to experience glaciers close to home, when possible. 

“We have one glacier in my state in Great Basin National Park, and it’s shrinking rapidly. It probably won’t last the next 20 years,” he said. “Right now, that’s a short drive for me to go see a glacier, appreciate it before it’s gone.” 

But he also understands the desire to behold glaciers far away, having recently visited Alaska himself and seen a handful of glaciers over several weeks. 

“We want to think about really making sure that we’re choosing sustainable methods to visit these these areas,” he said. “If we did have to use airline fuel and burn that carbon to get up there, at least we’re staying for longer.”  

What to know before visiting a glacier

“There have to be hundreds, if not thousands of opportunities up here in Alaska to see glaciers,” Sass said, encouraging people to “go see a glacier in a way that makes sense for them.” 

That may be appreciating them from afar by land, air or sea or getting up close with a guided tour.  

“We don’t expect people to hover above the ground and never interact with the natural world around us,” Esplin said. “It’s all a balancing act, a balancing act of humans being a part of nature, but also not destroying it entirely.”  

For travelers who want to get up close, Esplin shared these Leave No Trace-based tips: 

  • Plan ahead and prepare: “Usually that includes booking a guide service. It’s never recommended for anyone without sufficient training or expertise to go out on glaciers, as they’re constantly moving. They have crevasses, snow bridges and moulins. They’re usually (in) pretty remote environments as well, so that that safety aspect is one of the most important parts of interacting with glaciers.” 
  • Be mindful of where you tread. “We can affect the vegetation on the sides and really promote erosion in areas if we’re not utilizing trails or durable surfaces to get on and off that glacier. 
  • Pack out all waste, including food waste and human waste “so that it’s not being left behind to pollute that water source, that special place.” 
  • Remember wildlife. “They use (glaciers) to travel in between places… Even though you feel like you might be on an isolated world, wildlife can still be out there.”

Trump signs bills to ease way for drilling and mining in Arctic Alaska

Trump signs bills to ease way for drilling and mining in Arctic Alaska

President Donald Trump has signed bills nullifying Biden-era environmental protections in the Arctic National Wildlife Refuge and in Northwest Alaska in an effort to promote oil and mining activity.

The actions were a win for Alaska’s congressional delegation, which sponsored the measures to open opportunities for drilling in the refuge and development of the 200-mile road through wilderness to reach the Ambler mineral district.

The actions are part of Trump’s effort to aggressively develop U.S. oil, gas and minerals with Alaska often in the limelight.

Potential drilling in the refuge and the road to minerals are two of the standout issues in the long-running saga over resource development in Alaska, with Republican administrations seeking to open the areas to industry and Democratic administrations fighting against it.

The signings were a loss for some Alaska Native tribal members and environmental groups that had protested the bills, calling them an unprecedented attack against land and wildlife protections that were developed following extensive public input.

An Alaska Native group from the North Slope region where the refuge is located, however, said it supported the passage of the bill that could lead to oil and gas development there.

One of the bills nullifies the 2024 oil and gas leasing program that put more than half of the Arctic refuge coastal plain off-limits to development. The former plan was in contrast to the Trump administration’s interest in opening the 1.5-million-acre area to potential leasing.

The federal government has long estimated that the area holds 7.7 billion barrels of “technically recoverable oil” on federal lands alone, slightly more than the oil consumed in the U.S. in 2024. The refuge is not far from oil infrastructure on state land, where interest from a key Alaska oil explorer has grown.

Two oil and gas lease sales in the refuge so far have generated miniscule interest. But the budget reconciliation bill that passed this summer requires four additional oil and gas lease sales under more development friendly, Trump-era rules.

Voice of Arctic Iñupiat, a group of leaders from tribes and other North Slope entities, said in a statement that it supports the withdrawal of the 2024 rules for the refuge.

The group said cultural traditions and onshore oil and gas development can coexist, with taxes from development supporting wildlife research that support subsistence traditions.

“This deeply flawed policy was drafted without proper legal consultation with our North Slope Iñupiat tribes and Alaska Native Corporations,’ said Nagruk Harcharek, president of the group. “Yet, today’s development shows that Washington is finally listening to our voices when it comes to policies affecting our homelands.”

The second bill that Trump signed halts the resource management plan for the Central Yukon region. The plan covered 13.3 million acres, including acreage surrounding much of the Dalton Highway where the long road to the Ambler mineral district would start before heading west. The plan designated more than 3 million acres as critical environmental areas in an effort to protect caribou, salmon and tundra.

The bills relied on the Congressional Review Act, which gives Congress a chance to halt certain agency regulations while blocking similar plans from being developed in the future.

U.S. Rep. Nick Begich and Sens. Lisa Murkowski and Dan Sullivan attended the signing in the White House.

“We’ve known the road to American prosperity begins in Alaska; the rest of America now knows that as well,” Begich said in a post on social media platform X.

Begich introduced the measures. Murkowski and Sullivan sponsored companion legislation in the Senate.

They were part of five bills Trump signed Thursday to undo resource protections plans for areas in Montana, North Dakota and Wyoming, using the Congressional Review Act.

Trump last week also signed a bill revoking Biden-era restrictions on oil and gas activity in the National Petroleum Reserve-Alaska, another Arctic stretch of federal lands west of the refuge. That measure was also sponsored by the Alaska delegation.

The Wilderness Society said in a statement Thursday that the bills destabilize public lands management.

“Americans deserve public lands that protect clean air and water, support wildlife and preserve the freedom of future generations to explore,” said the group’s senior legal director, Alison Flint. “Instead, the president and Congress have muzzled voices in local communities and tossed aside science-based management plans that would deliver a balanced approach to managing our public lands.”

Alaska tribal members criticize end of Central Yukon plan

The Bering Sea-Interior Tribal Commission, consisting of 40 Alaska tribes, said in a statement Thursday that it condemns the termination of the Central Yukon management plan using the Congressional Review Act.

The action dissolves more than a dozen years of federal and tribal collaboration, the group said.

The termination of the Central Yukon plan will hurt tribes that hunt caribou and other subsistence foods, the group said.

“On the heels of the seventh summer without our Yukon River salmon harvest, we are stunned at the idea our leaders would impose more uncertainty around the management of the lands that surround us,” said Mickey Stickman, former first chief of the Nulato tribal government. “The threat of losing our federal subsistence rights, and confusion over how habitat for caribou, moose, and salmon will be managed, is overwhelming.”

After the signing, federal management of the Central Yukon region will revert back to three separate old plans, removing clarity for tribes and developers and requiring the Bureau of Land Management to start again on a costly new plan, the group said.

“This decision erases years of consultation with Alaska Native governments and silences the communities that depend on these lands for food security, cultural survival, and economic stability,” said Ricko DeWilde, a tribal member from the village of Huslia, in a statement from the Defend the Brooks Range coalition. “We’re being forced to sell out our lands and way of life without the benefit of receiving anything in return.”

Opinion: A new energy project, new risks and new responsibilities for Alaska

Opinion: A new energy project, new risks and new responsibilities for Alaska


Speaker Bryce Edgmon speaks with members of the Alaska House at the Alaska State Capitol on August 2, 2025. (Marc Lester / ADN)

Alaska may soon face major decisions about the future of the Alaska LNG project and, if so, the Legislature will need to ensure that every step serves the best interests of Alaskans.

It is essential to remember that Senate Bill 138, the blueprint for state involvement in Alaska LNG, was passed in 2014 for a very different project: one led by ExxonMobil, BP and ConocoPhillips, with a key role fulfilled by TransCanada. Today’s project is led by a private-equity developer, Glenfarne, pursuing a structure that diverges dramatically from what lawmakers contemplated more than a decade ago. When a project changes this much, the underlying statutes need to be revisited.

In June, the Alaska Gasline Development Corp.’s president told his board that AGDC would be coordinating with the developer, the administration and the Legislature regarding legislation needed to support project development. He also noted that AGDC would work with the administration and Legislature on policies required to exercise the corporation’s option to invest 5% to 25% equity at Final Investment Decision, or FID. When AGDC itself signals that legislation is necessary, we should look forward to their outreach.

SB 138 also assigned important responsibilities to the departments of revenue and natural resources that may require legislative action. One key responsibility is the Legislature’s authority to approve major gas project contracts negotiated by the DNR commissioner. The law clearly states that balancing, marketing and gas sale agreements for North Slope gas cannot take effect without explicit legislative authorization. That statutory requirement was intentional and recognizes a project of this scale demands legislative oversight.

We also know that the pressure for speed on complex megaprojects often backfires, sometimes creating more problems than it solves. The Legislature must balance the legitimate need for progress with the responsibility to ensure Alaskans are not asked to assume unreasonable financial risk. As Speaker Bryce Edgmon recently observed, legislation of this magnitude “could dominate the session” and “take significant time.” Senate Finance Co-Chair Bert Stedman was even more direct: if we get this wrong, it could be “detrimental for generations.”

Last week, 4,000 miles away in Washington, D.C., Glenfarne and POSCO International announced a major strategic partnership. It is a meaningful milestone. But Alaska has seen similar announcements before, and it does not diminish the need for hard questions. If anything, it raises them.

Final Investment Decision is when investors and lenders commit billions based on the project’s economics and the state’s fiscal terms. Any legislation affecting property taxes, payments-in-lieu-of-taxes, aka PILTs, state equity, fiscal stability, or upstream royalties and production taxes must be decided before this takes place.

The Legislative Budget and Audit Committee has focused on providing lawmakers and the public with the information needed to understand the choices ahead. I revisited the Legislature’s 2014 “Alaska LNG: Key Issues” report, which helped lawmakers evaluate the original SB 138 framework. Building on that model, I directed our consultants, GaffneyCline, to prepare an updated “key issues” report; not to endorse or oppose the current project, but to provide a high-level overview of potential policy choices, which should be available to the public within the next few days.

The refreshed “key issues” report will be an important starting point. I ask Alaskans to approach it with an open mind and to read it as objectively as possible, free from assumptions shaped by past disappointments or early optimism. Keep asking tough questions of the Legislature, AGDC, Glenfarne and the administration. Don’t assume the project is a done deal or a doomed one. This is not about cheerleading or obstruction, but insisting on rigorous analysis, strong oversight and a fair deal for our children and grandchildren.

Some Alaskans have raised questions about a potential conflict of interest: GaffneyCline is a subsidiary of Baker Hughes, which recently announced agreements with Glenfarne to help advance the Alaska LNG project. I share those concerns, which is why I have met with the Legislature’s director of Legal Services and with GaffneyCline’s North America director. I have been assured by GaffneyCline’s leadership that no one outside the GaffneyCline project team has influenced their analysis, and that their global reputation for independence and trust remains intact. Still, we also must fully vet this issue when we convene in Juneau next month. Transparency and independence are non-negotiable.

The recent ceremony in Washington, D.C., with Glenfarne and POSCO International underscores the project’s potential; however, the authority to determine how and when Alaska monetizes its resources rests here, not with dignitaries celebrating overseas commitments. Our future will be determined in Alaska, by Alaskans, based on the fullest and most honest understanding of the choices before us.

Sen. Elvi Gray-Jackson, D-Anchorage, represents Senate District G, which includes Midtown, Spenard and Taku Campbell in Anchorage. Sen. Gray-Jackson serves as the chair of the Legislative Budget and Audit Committee.
