Bubble-Net Feeding: How Humpback Whales Hunt Together in Alaska

February 13th, 2026 by Carl D
Humpback whales bubble-net feeding out of Sitka, Alaska
The feeding frenzy; spawning herring are a mouthful for this post of humnpbacks.

You hear it before you see it. A hiss of air breaking the surface, then a ring of bubbles appears, 25 yards across, expanding outward in a near-perfect circle. The water inside the ring goes dark. Shadows rise.

Boom.

The surface explodes. Mouths the size of pickup trucks burst upward through the center of the ring, wide open, pleated throats ballooning with seawater and herring. Five, six, seven whales at once. Tiny fish leap in every direction. The sound is part freight train, part waterfall.

The gulls go crazy.

And then it’s over. The whales slide back under. They blow a few times, the stench of half-digested herring drifting across the boat, and one by one they arch their backs and dive. The whole thing lasted maybe eight seconds.

Now we wait.

Again.

I’ve watched this happen hundreds of times across five seasons running our Hungry Whales Photo Tour in Southeast Alaska, and it still stops me cold. Bubble-net feeding is, without exaggeration, one of the most sophisticated cooperative hunting strategies in the animal kingdom. And it happens right here, in the cold green water off Sitka, every spring.

Patagonia Pumas

Last April I sat on the ground in open tundra somewhere on a private ranch bordering Torres del Paine, and a female puma named Escarcha walked past me at five yards. Not past the vehicle. Past me. I was sitting in the grass with a 400mm pointed at her and she couldn’t have cared less.

That was Day 5 of what was supposed to be a scouting trip. By Day 3, I already knew we’d be coming back.

Back to Patagonia

I first went to Patagonia in 2006. Spent four months on the Futaleufu River in central Chile, working with an international crew of guides. Rafting, kayaking, and photographing some of the most dramatic river landscape on the planet. It was one of those stretches that stays with you. Patagonia gets into your head. The scale of it, the light, the wind. It doesn’t feel like anywhere else.

The River From Deep Within: History and Ecology of the Noatak

Understanding one of the last great wild rivers in North America

The Noatak River begins on the north flank of Mt. Igikpak, the highest peak in the Brooks Range, and flows 425 miles to the Chukchi Sea. Its entire course lies above the Arctic Circle. Its entire watershed lies within protected wilderness. No other major river in North America can make both claims.

In Inupiaq, the river’s name is Nuataam Kuuŋa. Early translations rendered it as “passage to the interior” or “the river from deep within“. Both fit. For at least 10,000 years, the Noatak River has been a corridor for human movement through the western Brooks Range, connecting coastal communities with the interior. The people who named it understood what the river was: a path into a vast and wild country.

Largest Undisturbed Watershed in North America

The statistics are staggering. The Noatak drains 12,600 square miles. The Noatak National Preserve alone encompasses 6.5 million acres. Combined with Gates of the Arctic National Park, the protected area exceeds 13 million acres of contiguous, roadless wilderness.

More importantly, the watershed remains essentially unaltered by human activity. No dams. No roads. No significant development. The only permanent settlement along the river’s 400-mile length is the Inupiaq village of Noatak, population 400, located near the coast. Upstream, the country looks the same as it did when the glaciers retreated.

Backpacking the Brooks Range; Arctic Camping Trips

Backpacking the Brooks Range, in Alaska's Gates of the Arctic National Park.
Backpacking the Brooks Range in Fall can be gorgeous. Gates of the Arctic National Park.

The Philosophy of Trailless Travel in Gates and ANWR

Backpacking in the Brooks Range is not about following a line on a map. It is about learning to read the language of the landscape.

In the Brooks Range, there are no cairns, no signs, and no footprints that last more than a season. You are engaged in a constant, 24-hour-a-day exercise in micro-navigation. As John McPhee observed, the scale of this place is so vast that it can be disorienting. You’re operating in a world where the nearest road is hundreds of miles away and self-reliance and judgement is the only currency that matters.

Where is the Brooks Range?

The Brooks Range stretches 700 miles across northern Alaska, from the Chukchi Sea near the Canadian border to the western coast above the Arctic Circle. It is the northernmost extension of the Rocky Mountains. The Brooks Range forms the continental divide between rivers flowing south to the Yukon and north to the Arctic Ocean. The range rises abruptly from the boreal forest, crests at elevations between 4,000 and 9,000 feet, and drops onto the treeless coastal plain that runs to the Beaufort Sea.

Two of America’s largest and wildest protected areas occupy the Brooks Range. Gates of the Arctic National Park covers 8.4 million acres of the central range, including the granite spires of the Arrigetch Peaks and the headwaters of six designated Wild Rivers.

To the east, the Arctic National Wildlife Refuge protects another 19 million acres, from the forested valleys of the Sheenjek to the calving grounds of the Porcupine caribou herd on the coastal plain. Between them, these two areas represent the largest intact wilderness remaining in the United States. The nearest road, the Dalton Highway, skirts the eastern edge of Gates and provides the only ground access to the region. Everything else requires a bush plane, or a boat, skis or dog sled.

The Technical Reality: Tussocks, Eskers, and the Arctic Thump

The primary challenge of Brooks Range travel is the terrain. This is true of much of Alaska.

Camping in the arctic, however, is different.

Chitistone River, the Goat Trail, Wrangell-St. Elias

A trip report from one of my favorite backpacking trips: The Goat Trail and a hike down Chitistone River.

One gorgeous evening, a 2 mile hike (one-way) from camp and some more photos that I had been hoping for some time now to make. Lucky me!

We just trekked from Skolai Pass, in Wrangell St. Elias National Park and Preserve, to ‘Wolverine‘, a landing strip high above the Chitistone Valley, over the relatively popular ‘Goat Trail‘.

This is a classic hike, and one I try to make every summer. Before I talk about it further, I’ll qualify what I mean by ‘popular’ here.

Probably not 50 people hike this route each year, more likely 40, at most. Consider, for example, that nearly TWO THOUSAND people venture to hike the entire Appalachian Trail each year, and one starts to see that the word ‘popular‘ is entirely contextual. I only say ‘popular‘ here because so few people hike anywhere else in Wrangell-St. Elias National Park.

Six Days on the Upper Noatak: A Packraft Trip Through Gates of the Arctic

Float the largest undisturbed watershed in North America, where the Brooks Range opens into a treeless arctic valley unchanged for millennia.

The floatplane banks hard over a granite ridge and the valley opens below us. A ribbon of turquoise water winds through green tundra, flanked by mountains streaked with late snow. The pilot points out the window toward a blue lake tucked against the edge of the valley. That’s Pingo Lake. That’s where we’re going.

Two hours ago we were drinking coffee in Bettles, a village of maybe 50 people accessible only by air. Now we’re threading through the Endicott Mountains, past the spires of the Arrigetch Peaks, with 8,510-foot Mt. Igikpak filling the horizon. The flight into the Noatak headwaters is worth the trip alone. When the pontoons touch down and the engine cuts, the silence is immediate and total.

This is Gates of the Arctic National Park. No roads. No trails. No cell service. Just the largest undisturbed watershed in North America and a week to explore it.

Do You Need Rain Pants for Alaska Backpacking? (Yes, Here’s Why)

December 3rd, 2025 by Carl D

hey Folks,

When you’re packing for a backpacking trip in Alaska’s wet climate it’s important to think beyond just a rain jacket. It can rain a lot. You need to carry rain pants as well.

Does it Really Rain That Much in Alaska?

Travelers planning a trip to Alaska often wonder: Does it really rain that much in Alaska?

The short answer?

Well, I asked Trevor, our backpacking guide extraordinaire, who’s had more than his fair share of wet Alaska backcountry time. Trevor spends most of the summer walking around in the mountains guiding folks who wonder why he’s drier than they are.

“Yes, it rains. But not always in the way you might expect. Duration matters more than volume (typically).”

So how much rain are we talking about?

When it rains in coastal Alaska, it’s usually a lighter, steadier rain rather than a sudden downpour like the Rocky Mountain afternoon thunderstorms or the heavy East Coast rain events you may be used to. Think the Pacific northwest weather patterns.

Cold Weather Photography Clothing

Cold weather photography tips - from Snowshoeing, McCarthy, Alaska.

Key Takeaways: Staying Warm While Photographing

  • Three L’s rule: Loft, Loose, Lots – puffy layers that fit loose, and lots of them
  • Size up everything: Boots and gloves need to be bigger than you think for blood circulation
  • Solve the hand problem: 3-layer glove system + chemical warmers + pockets as warming stations
  • Act before you’re cold: Mitts on early, warming breaks every 30-45 minutes, movement generates heat
  • Know your temperature range: Different cold needs different gear (-10°F vs -35°F is completely different)

Winter Photography Demands Different Gear

The cold in Alaska, in the winter, is incredible.

Its stillness, its silence, its depth, and the intimacy of really feeling alone in the frozen north woods is an experience like no other. It’s almost as if the cold is some thing, some being itself, a tangible reality rather than a temperature. It’s a unique experience, and it’s not at all entirely bad – in fact, I love it.

But I don’t love freezing my tail off. My friend Patrick, longtime Alaska resident and a fantastic photographer says it best, “I like being in the cold, but I don’t like being cold”. #Truth

It’s really an extraordinary experience, and I do look forward to the winter. But I don’t want to be cold; I want to be bundled up and cozy, and enjoy the cold from inside my insulation.

Glacier Hiking for Backpacking Trips in Alaska

Guide Training in Wrangell-St. Elias National Park.

Hey Folks,

We run backpacking trips. Lots of them. We spend a lot of time on ice. A LOT of time. Over the years, collectively, the guides at Expeditions Alaska have clocked hundreds of miles walking, camping, relaxing, and exploring, on ice.

It’s such a big part of what we do, glacier travel is an integral part of our Guide Training Camp. I thought we might share some of the notes we reference for guides during that camp.

What You Should Know About Hiking on Glaciers in Alaska

Traction

Kahtoola Microspikes are great

  • “When do I put them on?” As soon as ice is the norm (not moraine/rock).
  • A lot of folks have trouble putting them on. Don’t skimp or rush it. Take your time. Make sure they’re on securely.

Rafting on the Canning River, ANWR, Alaska

Rafting Canning River, Arctic National Wildlife Refuge, Alaska.

Hey Folks,

Here’s a photo of us rafting down the Upper Marsh Fork of the Canning River – essentially the headwaters of the Canning in the Brooks Range, close to the continental divide.

How Do We Get Here?

We go to ANWR via Coldfoot, and fly in tot he backcountry from there. Our favorite Alaska air taxi, Coyote Air, drop us off and pick us up for the return to Coldfoot. Then we overnight in Coldfoot and the next day return to Fairbanks.

Some of the trips we drive Fairbanks – Coldfoot, and some we fly. Varies trip to trip.

About The Canning River

The river here has eroded its way through the layers of bedrock to form this really neat little mini-canyon. I hopped out of the boat to take some photos of the run. Actually, we ran it several times, and I shot each time, some horizontals, a few verticals, some wider, some tighter, trying to get different compositions of essentially the same scene. I like this one the most, I think the vertical frame gives heightens the sense of action of the rafting, and accentuates the canyon walls and the mountains – it’s not as spacious as some of the horizontal compositions, but it feels closer to what the experience was for me.

For me, any photograph should strive to do that – present the experience of the photographer. I emphasize that in our Photo Tours.
