Just west of Seward, Alaska, Kenai Fjords National Park is where a massive frozen relic of the last Ice Age still spills down to meet the sea. At its heart sits the Harding Icefield, a sprawling plateau of ancient ice that feeds nearly 40 glaciers, some of which calve directly into the deep, glacier-carved fjords below. Add in bellowing sea lions, breaching whales, and cliffside seabird colonies, and it’s easy to see why this compact park packs one of the wildest coastlines in America. Here are 25 fun facts about Kenai Fjords National Park.
1) Kenai Fjords covers 669,650 acres (about 1,047 square miles) on the southeastern edge of the Kenai Peninsula.
2) The park was first protected as a national monument in 1978, then upgraded to full national park status in 1980 under the Alaska National Interest Lands Conservation Act.
3) Nearly half the park is buried under ice, almost all of it flowing from the Harding Icefield.
4) The Harding Icefield spans roughly 700 square miles, making it one of the largest icefields entirely within the United States.
5) At its widest, the icefield stretches about 50 miles long and 20 miles wide.
6) The icefield’s surface can reach elevations of about 5,200 feet, buried under snow and ice so deep the mountain peaks poking through it are called nunataks.
7) At least 38 named glaciers flow outward from the Harding Icefield in every direction.
8) More than a dozen of those glaciers actually terminate inside the park, including Exit, Bear, Aialik, Holgate, Northwestern, McCarty, and Pedersen.
9) Bear Glacier is the park’s longest glacier, stretching about 20 kilometers (roughly 13 miles) before ending in its own glacial lake.
10) Exit Glacier is the only part of the park reachable by road, via a short drive and walk from the Seward Highway.
11) Exit Glacier is also one of the most visibly shrinking glaciers in the Lower 48-plus-Alaska, and rangers use it to teach visitors about glacial retreat in real time.
12) Several glaciers, including Aialik and Northwestern, are true tidewater glaciers, meaning they flow all the way to the ocean and calve icebergs straight into the fjords.
13) Calving happens year-round, but the best viewing window is mid-June through August, when the outer fjords are most accessible.
14) Glacial ice glows electric blue because dense, compressed ice absorbs red light and scatters blue light back to your eyes.
15) Between 1950 and 2005, the park’s glaciers lost about 252 square kilometers, roughly 11% of their total ice.
16) The park’s fjords themselves were carved by advancing glaciers during the Pleistocene, then flooded by the sea as the ice retreated, leaving behind steep, U-shaped valleys.
17) Some fjord floors plunge 600 to 1,000 feet below sea level, walled in by sheer cliffs that rise straight out of the water.
18) Truuli Peak, at 6,612 feet, is the tallest peak associated with the Harding Icefield.
19) The park’s waters are a magnet for marine life, with humpback whales, orcas, Dall’s porpoises, and Steller sea lions all common sights on boat tours.
20) Humpback whales here are famous for bubble-net feeding, a cooperative hunting trick where whales blow rings of bubbles to corral fish before lunging through the surface together.
21) Rocky islets along the coast host noisy rookeries of Steller sea lions, one of the largest concentrations found anywhere in Alaska.
22) More than 300 bird species have been recorded in the park, including tufted puffins, horned puffins, and kittiwakes nesting on sheer sea cliffs.
23) Long before it was a park, the Kenai Fjords coastline was home to the Alutiiq people, who built a life around the sea’s resources for generations.
24) The park has just one developed campground, along with backcountry and marine sites for kayakers willing to paddle out to remote coves.
25) Because there are so few roads, most visitors experience Kenai Fjords by boat, kayak, or flightseeing tour out of Seward, making it one of the more adventurous national parks to explore.
From tidewater glaciers thundering into the sea to whales bubble-net feeding just offshore, Kenai Fjords proves that some of the wildest scenery in America still requires a boat ticket to reach. Pack a rain jacket, book a tour out of Seward, and go see the Ice Age up close while it’s still calving into the Gulf of Alaska.
