Kenai Fjords National Park
Ice and Eskimo
Ice stretches
across the Alaska horizon as far as the eye can see, interrupted by
an occasional jagged nunatak, Eskimo for "lonely peak. The Harding
Icefield’s expanse covers more than half of 607,805-acre Kenai
Fjords National Park and conceals a mountain range under ice
several thousand feet thick. Named for President Warren G. Harding,
who visited Seward in 1923, the Icefield is a relic from the last
ice age. It gives us a glimpse back to when ice covered much of
North America. But Kenai Fjords is no static window to the past…as
the ice recedes, it uncovers glacially carved valleys that fill
with sea water to form the stunning fjords (pronounced f’yords).
Visitors witness nature’s raw power sculpting this landscape.
House-sized ice masses crash from tidewater glaciers into an
Alaska sea, stirring up plankton to attract throngs of hungry
seabirds. Along the coast Earth’s crustal plates collide head on:
the denser Pacific Plate slips under the North American Plate. This
subduction drags the Kenai Mountains into the sea and deepens the
fjords. It causes frequent earthquakes, too. In 1964 the Good
Friday Earthquake dropped the shoreline six feet in 3.5
minutes.
Puffins, Otters and Sea Lions in the US National
Parks
Plants and animals adapt to incredibly dynamic conditions to
survive the fjords. In this strange and wonderful place birds swim
better than they fly. Ice-worms exist on frozen glacier surfaces.
Mammals are better adapted to life in frigid salt water than on
land. Puffins, kittiwakes, otters, sea lions, orca, salmon, and sea
stars: the diversity of life in these seemingly inhospitable fjords
is beyond our wildest imagining. Throughout the year storms drop
hundreds of inches of snow on higher elevations. Snowflakes compact
into dense glacial ice and feed 32 glaciers that flow from the
Icefield. Rivers of ice, they creep downhill like giant bulldozers,
carving out bowl-shaped cirques and broad U-shaped valleys. At Exit
Glacier – the only part of the park reached by road – you can get
close enough to peer into deep blue glacial crevasses. Keep a safe
distance though! Although retreating, Exit Glacier is active. Large
blocks of ice calve from its face without warning. The short stroll
to Exit Glacier is like a trip back through time. Here the story
unfolds of how plant life reclaims barren rocky land exposed by the
glacier’s retreat. The Sitka spruce-and-hemlock forest you first
encounter gives few clues that less than 200 years ago ice covered
the area. Closer to the glacier you see earlier stages of growth –
cottonwoods, alders, and willows – preparing the way for the
‘climax’ forest. Finally, in the area most recently exposed, you
will find pioneer plants – mosses, lichens, and bright pink
fireweed – struggling to gain toeholds in the aftermath of nature’s
great bulldozer. These colonizers start the progression from
glacial till to the temperate rain forests that cloak the edges of
the Kenai Fjords.
Alaska Bald Eagles
Wedged
between the sea and the Icefield, wildlife flourishes in this
narrow slice of temperate rain forest. Mountain goats pick
their way along precipitous slopes. Moose browse hedges of
willow and alder. Bears forage for grasses and berries.
Wolverines, marmots, and songbirds also make homes here. Some
species span both worlds: bald eagles fish in the fjords and
nest in the tops of spruce or hemlock trees.
Eskimo, Fur Traders and Gold Seekers
Native eskimo hunted and fished in the fjords for years. Russian
fur traders and gold seekers passed through. Most evidence of these
humans fell victim to this harsh environment, but the park includes
a few Native Alaskan archeological sites and gold mining sites. The
National Park Service manages Kenai Fjords to preserve its natural
and cultural resources, ensuring that people can enjoy this dynamic
place while leaving it unimpaired for the enjoyment of future
generations. Established as a national monument in 1978, Kenai
Fjords became a national park under the Alaska National Interest
Lands Conservation Act (ANILCA) in 1980. But the story of Kenai
Fjords is far from finished. The Earth’s crustal movements keep
tugging the mountains into the sea, and changes in temperature and
precipitation cause glacial advance and retreat. If you return, the
park won’t look quite the same – in Kenai Fjords the only constant
is change. Here mountains and the sea struggle for balance,
glaciers advance and retreat, wildlife adapts, and nature is always
a work in progress.
