From the Aleutians to the Brooks Range, Alaska hot springs flourish far and wide


After a few hours of skiing through deep snow, Forest Wagner and I smelled a tuna sandwich. We knew we were closing in on warm pools of water.

From the frozen Kanuti River, we moved along an open stream up toward Kanuti Hot Springs, one of more than 100 hot springs in Alaska.

Hot springs exist from Attu in the Aleutians to the northwest Brooks Range to as far south as you can get in Southeast.

Most are on or near volcanoes, with very hot water bubbling or steaming up from deep below, where Earth’s great crustal plates are grinding past one another.

In non-volcanic areas of Alaska like the Interior, deep warm rocks that were once magma are the heat source. Water that falls as snow and rain percolates down until it reaches those hot rocks. Superheated, that water rises, snaking upward through fractures in the ground and pooling on the surface as steaming water.

A few years ago, on a windy spring day, Forest and I skied into a clearing and found Kanuti Hot Springs, about 13 miles from where the Dalton Highway crosses the Kanuti River.

Kanuti is in a field of brown grass surrounded by a forest that was then covered with 2 feet of snow. The thawed acre featured several pools of hot water. We pulled our mittens off and stuck our bare hands in the largest one. We were in luck: The temperature was about 110 degrees Fahrenheit, not too hot, not too cold.

Using our ski-pole baskets as strainers, Forest and I scooped out floating algae and greenish blobs of cyanobacteria. These heat-loving microorganisms give hot springs their splashes of color, from white in water close to the boiling point to yellows and oranges in cooler pools.

Living things floating in water were not the only exotic organisms there, 15 miles south of the Arctic Circle. In the field around us grew a grassy fern known as fowl mannagrass. It does not exist in valleys on either side of Kanuti Hot Springs. It only grows there and in one other hot spring in Alaska. Somehow, some way, seeds of the plant found their way to this heated meadow behind Caribou Mountain.

American dippers, roundish birds that feed underwater year-round, live near many hot springs and the unfrozen creeks the warm water enables. We saw none at Kanuti, but a pair has nested behind a waterfall emerging from Melozi Hot Springs near Ruby.

The trees surrounding the Kanuti clearing are typical of the boreal forest, but Pilgrim Springs on the Seward Peninsula is home to spruce and pine trees, planted by someone during that place’s long occupation. Balsam poplar trees also grow there. Pilgrim Springs was home to a pair of nesting great horned owls when I once visited. Surrounded by an ocean of tundra, the forest-dwelling birds might have lived their entire lives on that island of trees.

In places like Pilgrim, Manley and Circle hot springs, people have used the warm water to heat lodges and greenhouses and have planted large fields of vegetables in the microclimate of warm soil. The operators of Chena Hot Springs, connected by road to Fairbanks, are generating their own electricity using the temperature difference between hot and cold water.

For many years, scientists and engineers have studied the potential of Alaska hot springs to provide heat and power for communities dependent on diesel fuel. Very few of the projects have progressed beyond the initial stages.

Why? That reason was obvious as Forest and I soaked in Kanuti Hot Springs, hearing only the wind whistle through birch branches. Most Alaska hot springs are like Kanuti — in windy places near lonely bends of a river, far from anywhere Alaskans call home.

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

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.
