26 July – Kenai
Fjords
What a different landscape!! Today we took the 4 hour boat
ride out of Seward to the Kenai Fjords Glacier Lodge, at the base of the Pedersen Glacier –
the only lodge inside Kenai Fjords National Park. We’ll be here for the next
two days, exploring the ecoystem surrounding this coastal habitat, and
hopefully seeing some very different plants and animals.
Kenai Fjords contains the many fjords created by the Harding Ice Field, a 700 square mile area of ice that has caused dozens of glaciers to push through into the sea. The geology of this area is what caused the formation of the ice field – the Pacific tectonic plate subducted under the North American plate millions of years ago, creating such mountain ranges such as the Alaskan, Brooks and this Chugach Range. The proximity to the ocean allows for a weather pattern that produces vast amounts of precipitation; in some years, the Harding Ice Field gets over 100 inches of snow. The pressure caused by the accumulation of this much weight is what created the ice field, and like a tube of toothpaste being squeezed, the ice is getting pushed out through the mountain channels in the form of glaciers.

A fjord is any bay created by a glacier and filled in with
water – it’s a remarkable ecosystem that is uniquely suited for an abundance of
wildlife. At times during their creation, the glacier pauses and sediment from
the glacier is deposited at a certain spot; this means some bays such as Aialit
Bay where the Kenai Fjords Glacier Lodge is located has dramatic depth changes
because of undersea shelves – at points the depth goes from 700 meters to 35
meters, then back down to 700 meters. Upwelling from currents makes for strange
pockets where sometimes hunks of ice accumulate.
Additionally, minerals carried by glaciers feeds these
coasts, and the nutrient rich water is ideal for algae, jellyfish, plankton,
and small fish. This in turn drives up the larger marine mammal and sea bird
populations.
As we drove out of Seward harbor, we first saw a small group
of sea otters. They just stared curiously, but were unafraid even when we
drifted to within 25 feet of them. It interesting that they were the first
animal we saw, since the establishment of Seward and the very first arrival of Russian
traders in this area was driven by the desire for sea otter pelts. Otters have some of the
warmest, softest hair in the world – they can have up to 1 million individual
hairs per square inch (in comparison, humans might have around 100,000 hairs on
their entire head).
We stopped to see Spire Cove which look like fingers
sticking out from the sea. They're leftover from the time when glaciers retreated from the bay, carving out the many inlets and leaving interesting formations. From there, we saw several sea birds, including
cormorants and horned puffins. Puffins are funny looking birds – easiest to
describe as flying potatoes. They flap furiously to keep in the air, but
amazingly they “fly” just as well underwater while trying to catch fish.
As we continued out of Resurrection Bay, we were surprised
by a pod of about 7 orca. They started a few hundred yards away from us, but as
they came closer they suddenly started to breach. Our captain Shawn said in the
10 years he’d been here, he had never seen a male breaching so we got lucky.
About three of them jumped out of the water two or three times each – it was a
great show.
Our next stop was to the Holgate Glacier, to see the
incredibly blue ice. As we drew close, we could feel the cool air coming off
the top, known a katabatic wind. A few small pieces came off but we didn’t see
or hear any of the major calving.
Near Holgate, we saw a strange cloudy area in the water;
getting closer, we realized it was a smack of jellyfish (love that it’s called
a smack!) – moon jellies. There were thousands in the grouping, all clustered
together feeding on whatever was in the water at that point.
We got to the lodge right by Pedersen Glacier soon after 2pm
and walked the half mile to the lodge. From here we can see lower Pedersen
Lagoon, and across from that, Pedersen Glacier on the lagoon's far side. After checking
into our room (Puffin), we went on a canoe ride into the lagoon. It was
drizzling, but the lodge provided us with wading boots and waterproof pants.
The lagoon itself is really calm brackish water – fed on one side by a small
channel into the bay for salt water, and by a stream of glacial melt on the
other bringing in fresh water.
We saw several more marbled murrelets and pigeon guillemots
(some of which took off flying by running across the water and furiously
flapping before taking off – reminding me of a B-52 bomber in their lumbering
gravity-defying way – showing us their bright red feet). We also saw several
harbor seals and two sea otters.
We made it back to the lodge in time for happy hour, where
they were serving “glacieritas” – margaritas served over glacier ice that had
been harvested by one of the naturalists. (I had a soda water over glacier
ice. Refreshing!). The group is very friendly, many of whom were interested in our project,
which was nice to hear!
27 July – Kenai
Fjords
It was a wet, wonderful, active day today in Kenai Fjords!
We had breakfast here at the lodge, with the wide picture window looking out
into Pedersen Lagoon. On clear days, you can see the glacier in the distance but that morning was drizzly and a bit foggy. Even so, it's a beautiful view - we even saw a young black
bear walking past the window!
We did the Pederson Glacier hike for the morning activity – we took the kayak across Pederson Lagoon (after stopping to see a sea otter with her baby) and hiked about a mile through the rainforest (and rain) to Upper Pederson Lagoon.

But it was interesting to see the different types of
vegetation that changed as we got closer to the glacier – it has receded almost
1500 feet in the past 100 years so the areas closer to the glacier are really
mossy, gravel/rock-strewn, and have no larger trees or brambles. Our guide,
Benny, is a bird expert, and he gave us some
interesting insight to being out here in the Alaskan backcountry. He thinks of
‘wilderness’ as being more a state of mind than a place, which then makes it
easier to understand wilderness if you don’t have the ability to actually go
there and experience it for yourself.
We went back to the lodge for lunch, dropping our wet things
off in the drying room (a room heated by the residuals from the generators and
kept at around 100 degrees – which easily dries all our wet items in just an
hour or two. Genius!).
In the afternoon, we went on the Addison Lake hike –which was great for seeing the different types of salmon which come up to spawn. Guide Grace took us along with George and Susan (the couple from Florida that we met on the boat ride over). We canoed across the lower lagoon and hiked about an hour across to Addison Lake, where we dragged another canoe into the water. It is just about the time of year for spawning, which means they have been using all their energy to get ready (thus turning basically into zombie fish which will soon die).
Salmon are interesting because they are born in freshwater, swim into the ocean to live for 2-6 years, then swim upstream against the current to return to the lakes and ponds where they were born in order to lay their eggs. In their ocean stage, salmon all look fairly uniform – a silvery color. When they are ready to reproduce, their colors and bodies change; the males get their distinctive hooked mouths, they change to their bright red-orange-green colors, and the bodies of some species build up muscle to help them make it up the rivers to their lake birthplaces. Once they spawn, they die, and their bodies return to the pond to feed the multitude of organisms that thrive there – including their babies. In Addison Lake, we saw Chum, King, and Sockeye salmon.

We also saw a black bear in the distance, a harbor seal, a
bald eagle, and a family of swans in the lake. On the way back to the lodge, we
decided to do some audio recording which means we had a “quiet paddle” and for
a few minutes even stopped paddling and just sat silently listening to nature.
It was really cool to hear the rain pattering on the lake, the cries of the sea
birds who were excited about a chum ball dropped by one of the boats, and the
occasional splash from different diving birds, seals, otters, or fish. To the
side we could hear the running of several small waterfalls feeding down into
the lake. It was definitely something special and helped us notice things we
most likely wouldn’t otherwise have noticed.
28 July – Kenai
Fjords to Cooper Landing
This morning we woke up to sunny skies and a clear view of
Pedersen Glacier. We went on the Slate Island kayak tour – after an early
breakfast, we split up from the main group and had a tour with guide Randy,
Jeff (an employee of Alaska Wilderness) and his girlfriend Jen. It was nice
having a semi-private tour – we talked to several of the guides who were all so
supportive of our project and willing to help us out.
Randy took us out 2 miles to Slate Island, where we were
able to kayak partway into a couple caves.
Because we went first up the eastern
side of the island, we got a wonderful view of Aialik Glacier right when we
reached the end of the island.
There was a small gap between the main island and a smaller outcropping, and we could just see the first peek of the glacier between the gap. Randy maneuvered us through the narrow gap, where the current shot us out the other side and into full view of the glacier. We could hear the rumbling of the calving glacier, and the air was definitely cooler on that side of the island.
Being down on the water and looking up at the huge glacier was deceptive – it felt as though we were really close, but we were still about 3 miles away from the base of the glacier!

On the northwest corner of the island, we found a bald eagle
nest on a spruce tree; we waited a few minutes and a bald eagle came soaring
into view and landed on the highest ledge above the tree. In the water we saw
hundreds of tiny (quarter and dime sized) moon jellyfish, with one or two
lion’s mane jellyfish thrown into the mix.
It was a smooth, easy paddle back to shore – overall a
beautiful morning. We left the lodge at 2 to return to Seward on the sightseeing boat. First we stopped
in a small bay across from the lodge to see a huge smack of moon jellyfish. It
was much larger than the one we saw on the ride in, and the water was so clean
and clear that we could easily see through the water and notice the gorgeous
patterns in each individual jellyfish.
Along the intertidal zone we saw dozens of sea birds –
including both tufted and horned puffin, pigeon guillemot, cormorants, glaucous
gulls, and kittiwakes. Along an outcropping, a small group of Stellar sea lions
had hauled out – most likely just to rest.
Crossing Resurrection Bay, we were greeted by a humpback
whale. Humpbacks come to this part of Alaska to feed on the rich bounty of
krill fed by the glacial waters, some coming from as far away as Baja
California, Hawaii, and Japan. They typically dive for around 6 minutes, and we
watched it dive twice – when it does, it flashes his fluke (tail fin) – each
humpback can be identified by the individual bumps and ridges in the tail.
Right before coming in to Seward, a huge, bright rainbow
appeared, right next to Paradise Glacier. It was the perfect way to end a great
expedition.
29 July – Kenai
Peninsula to Anchorage
A nice and relaxing day today! We spent last night in Cooper
Landing, mainly because Seward is so expensive. But we decided to drive back to
town this morning to see Exit Glacier. We had breakfast at the Train Rec (the
small grouping of renovated train cars that is a landmark in Seward), then went
out to the Exit Glacier Visitor Center. We picked up the Discovery Backpacks
for the Junior Ranger Program – there’s one for art and another for science – a
great idea to get a more in-depth experience at Exit Glacier. And it’s for all
ages even though it is geared for kids, but I personally think everyone should
do it in order to enrich their experience in the Park!
We joined the guided hike to the base of the glacier,
stopping at various points along the way. It was disheartening to see the signs
posted for the terminal ends of the glacier during different years in the past
– in the last 100 years, it has receded over 1,000 feet and is melting faster
and faster. There’s even a small structure built in the 1980’s that was meant
to be the end viewpoint of the glacier – today, you can’t even see very far
because the view is completely obscured by alder, birch, willow, and pine
trees. And even if the vegetation were removed, the glacier is so much further
up the valley that it wouldn’t give a very good view.
We stopped near the end of the trail to open our Discovery
Backpacks – we decided to do the art activity, which instructed us to create a
piece of work based on what we saw. Gemma and I used colored pencils while Anil
made a watercolor, all of the view to Exit Glacier. It was actually amazing how
much detail you observe when you take the time to truly look - seeing the different colors in the
earth, the trees, and especially in the glacier itself was amazing.
On our hike back, we saw a little vole darting across the trail.
It was the only wildlife we saw, despite the fact that the main trail to Exit
Glacier was closed because of a black bear sow and her two cubs that were
roaming around the area.
After stopping at the post office and having a quick lunch,
we went to the Alaska Sealife Center based on several recommendations. It’s a
great little aquarium, reminiscent of the Monterey Bay Aquarium, but focusing
on the marine diversity particularly in the Kenai Fjords area. It was
particularly interesting to see an up-close view of the horned and tufted
puffins, since they’re so skittish in the wild and hard to get close to.
On our drive out of Seward and up the Turnagain Arm, we
stopped at one of the pullouts to see the view of the arm. It was a low tide,
but not the right time for the Bore Tide so we didn’t see the dramatic change
in sea level. Even so, it’s a beautiful drive, and it was hard to say goodbye
to the Kenai Peninsula!
