After lunch on 24th June, the “Sea Lion” relocated further north up Chatham Straight to Sitkoh Bay which is a narrow inlet on the southern end of Chichagof Island and directly across the Straight from Angoon.

The story of this bay provides an insight into the consequences of the way resources are harvested and why it’s so important to understand and respect relationships in the environment. This is a story that wasn’t told to us on board the ship, but it probably should have, could have, been. It’s a story I’ve had to piece together from my own research.

This 8 km (5 mile) long bay is fed by the Sitkoh River which, in turn, is fed by a mountain lake. And that’s just the type of environment Sockeye salmon require in order to spawn. But this type of stream is comparatively rare in South East Alaska and, when man changes and spoils this pristine environment, so the numbers of Sockeye decrease markedly.

Summer Camps on Sitkoh Bay

Summer Camps on Sitkoh Bay *

The first humans known to come to this bay were groups of native Tlingits who made their summer camps along the edges of the bay. Tlingits had lived in South East Alaska for 10,000 years before the first white men arrived. They were subsistence harvesters of fish and they understood the importance of not over fishing and also the need to keep the environment clean for the fish to spawn. They fished according to their need.

Each year, the Tlingits harvested some of the Sockeye as they moved upstream. At that time, the fish were full of fat; good food but difficult to smoke for later consumption. These were eaten immediately. Fish caught after spawning, the ones that would die naturally anyway, were less fatty and able to be smoked for later use in winter. There was a healthy balance between man and resource.

Sitkoh Bay in Relation to Sitka *

The first pressure placed on the numbers of Sockeye in the bay came after the Russians took the land around Sitka by force in 1804. Many Tlingits fled over the hills from Sitka to live in the Chatham Straight area. More people put pressure on the bay in summer and fights broke out between the different groups. But there were still sufficient Sockeye salmon for all.

This balance in nature changed dramatically in the years after the Chatham fish processing plant was built in 1900. It was set up to take advantage of the rich resources of Sockeye in this bay.  When the Tlingits expressed their views on the way the fish were being over-harvested, they were silenced by armed US guards. The price for good red Sockeye was high in the market and the Cannery made of the most of Sitkoh’s summer spawning runs.

While some Tlingits were employed by the cannery, at a very low rate of pay, the owners of the cannery continually refused to listen to them about the need to take fewer fish. As a result, by 1920, the numbers of Sockeye had begun to diminish markedly.  Eventually, the cannery closed in 1974 but not until the Sockeye had been almost totally fished out. 

The third pressure that beset the Sockeye salmon was forest logging around the mountain lake that fed their spawning stream. Logging took place in this pristine valley between 1969 and 1974 and, according to research reports, silt had a big effect on muddying the stream and on changing the water temperature. Since logging ceased, efforts have been made to clean up the water ways and the Sockeye are recovering in number. Fortunately, nowadays more is known about the interdependence of life in the wilderness and changes are being made.

There’s not much left of the Chatham Cannery site and its village. When in use by the Cannery, the inhabitants were segregated into three areas; White owners, Asians and Tlingits. It’s still used by Tlingit peoples for summer harvest of salmon.

No-one uses this jetty anymore. It stands as a mute reminder of the days of the cannery and the consequences of not understanding the needs of a natural resource.

The famous American wilderness explorer, John Muir, once said, “To the lover of wilderness, Alaska is one of the most wonderful countries in the world.” And it is indeed amazing… especially when you have the privilege, as I did at Pond Island, to just float quietly on still waters taking in the beauty that surrounds you. Let me share it with you.

Much of the time, as we moved slowly along the shoreline, we just enjoyed the peace and the beauty of the wilderness that surrounded us, especially the reflections in still waters.  That peace was only broken when we saw wildlife along the way. Then Jason would quietly tell us something about each one as we observed their behaviour in the wild.

This was the first day on this expedition that the kayaks were in use.

The conditions were perfect for that activity.

Some of our group, like David, had chosen to walk, some to kayak and some, like me, to explore by DIB. We all enjoyed the beauty of this wilderness area in our own way.

At one end of the bay was a rocky island, a perfect example of a conifer forest surrounded by the deeper green of the much smaller Sitka alders.

Pair of Bald Eagles ©  JT  of  jtdytravels; P1130942

The island provided a great look out point for a pair of bald eagles. It’s hard to tell which is male and which female, they look so similar. The female is, in fact, slightly larger.

Bald eagles are the national bird of USA, indeed it’s the only bird unique to North America. Its scientific name is  Haliaeetus leucocephalus; from Greek hali “sea”, aiētos “eagle”, leuco “white” and cephalos “head”. About half of the world’s 70,000 bald eagles live in Alaska so it’s not a surprise to see them here. In this bay, the eagles were on the look out for salmon as the annual salmon run was just beginning. They will eat both dead and dying fish.

It was good to watch the eagles in the wild away from human habitation. Further south in the ‘Lower 48’ states, bald eagles and other birds of prey such as kites and hawks, are vulnerable to toxic chemicals in the environment. Because these birds are at the top of the food chain, each link in that food chain tends to concentrate chemicals from the lower link. Here, in  the wilds of South East Alaska, they are free from that danger.

P1130944

Salmon run creek ©  JT  of  jtdytravels; P1130944

We gradually made our way towards a small creek where salmon were beginning to congregate for the start of their annual spawning run. Five types of salmon occur in Alaska, easily remembered by looking at your fingers! Thumb = Chum; Pointer = Sockeye ( a bit obscure but it helps to have a bit of imagination!); Middle finger = King; Ring finger = Silver; and Pinky finger = Pink.  In general, adult salmon eat other fish, squid, eels, and shrimp. However Sockeye salmon has a diet that consists almost entirely of plankton.

Another small, rocky island had no trees,

just grasses and the delightful red paintbrush, Castilleja miniata.

If we had been able to have a closer look at the red paintbrush plant, as David did while walking on the shore, we would have seen that the red parts are actually modified leaves, or bracts.  The flower is tiny, protected by the bracts.

P1130952

Inside salmon pool ©  JT  of  jtdytravels; P1130952

As we turned the corner, we came into a small pool where the salmon collect before their final spawning run. Alaskan salmon are anadromous, meaning they are born in freshwater (rivers or streams) before they travel to and live much of their lives in salt water. They then return to freshwater to spawn. It has long been believed that salmon return to the exact spot where they were born in order to spawn. Recent tracking studies have shown this to be mostly true although some do stray and spawn in different freshwater systems. Such homing behaviour is quite an amazing phenomenon and has been shown to depend on olfactory memory.

When the female reaches the place where she will lay her eggs, she makes a depression in the river or creek bed with her tail, and then deposits some of her eggs.  She then waits for males to fertilise the eggs before covering the depression. She then moves on to make another depression. Females will make as many depressions as they need in order to lay all of their eggs; that may be up to seven depressions.

After spawning, the adults die and thus provide more food for bears and eagles.

Young salmon will stay for six months to three years in their natal stream.  Only 10% of all salmon eggs are estimated to survive that period. As they prepare to leave the creeks for the ocean, their  body chemistry changes, thus allowing them to live in saltwater.  They will then spend about one to five years (depending on the species) in the open ocean.  There they gradually become sexually mature and prepare to return to the creeks of their birth. It’s another of the wonderful stories of nature.

As we sat quietly in this pool area, enjoying the reflections, we noticed movement. A female merganser was moving along beside the shore. She was very watchful of us, as we were of her! We stayed very still and she seemed to accept our presence.

P1130969

Baby Mergansers © JT of jtdytravels; P1130969

She was followed by her brood of ducklings. They are similar to their mother except for a short black-edged white stripe between the eye and bill. They were wonderfully camouflaged against the barnacles, rocks and sea weeds. We stayed our distance and watched them.

These birds, Mergus Merganser, need nesting holes in the mature trees of these forests for breeding. The female lays usually 8 to 12 white to yellowish eggs and raises one brood each season. This one had five ducklings with her; maybe others had fallen prey to predators. As soon as the eggs hatch, the female takes the ducklings in her bill down to the pool or river. They feed on freshwater invertebrates and small fish fry. They are fully fledged when 60–70 days old but are not sexually mature until they are two years old.

Pair of marbled murrelets © DY of jtdytravels; P110025

Back out in the main bay we saw a pair of Marbled murrelets, very small sea birds with a very long Latin name: Brachyramphus marmoratus. They’re difficult to photograph partly because of their size and partly because they are very busy little birds, constantly diving to feed on sand eels, herrings and other small fish. They feed in pairs and we saw them often as we sailed in the waters of the Inside Passage where they are never far from a forest.

Old growth forests are especially important to Marbled murrelets. Unlike other sea birds, these little birds nest on the mossy branches of old trees, particularly the hemlock and the spruce so prevalent in these forests. This habit of nesting in trees, rather than on cliffs and rock ledges or in burrows like other sea birds, was not documented until 1974 when a tree climber found a nest. It was a rather remarkable finding and has had important implications for the logging of old growth forests in the area. In many places on their habitat range, this species of murrelet has declined in numbers because of logging.

Even without the pressure of the logging of their nesting trees, murrelets are hard pressed to succeed in the breeding process. After choosing a tree with lots of moss and lichen on the branches and with plenty of cover from predators, the female murrelet lays just one egg on a platform of lichen and moss. After a month of incubation, the chick hatches and is fed for about forty days until it’s able to fledge and fend for itself. Breeding success is low and chick mortality is high. We were entranced by these little birds each day of the expedition.

Harbour Seal ©  JT  of  jtdytravels; P1130977

Every now and then, a round grey head would pop up on the surface, have a quick look around and then slip quietly away again beneath the surface. This was a harbour seal. They don’t stay long on the surface and are hard to photograph in the wild because it’s not easy to predict when they will resurface. They stay down for quite a while as they seek fish, squid and shrimp. In 2010, an aerial survey of harbour seals in Southeast Alaska estimated that there were 60,000 harbour seals in these cold, fish rich waters. They are a delight to observe.

These are tidal waters, so the DIB drivers put out buoys to mark rocky areas that would become shallower as the day went on. The forest reflections were lovely.

Happy kayakers gradually came back closer to shore.

Their time afloat was almost over.

It would take some time to collect the kayaks and take them back to the ship.

Sadly, it was time for me to go back to the “Sea Lion”; the Dibs were needed for other tasks. Meanwhile, David was still on shore doing a beach walk while he waited his turn to return to the ship. So next time, we’ll wander along the shore here at Pond Island with him.

After lunch on Day 2 of our exploration of Alaska’s Inside Passage, we cruised back along Frederick Sound towards the small fishing town of Petersburg; it was the only town we would visit on this trip. As you can see, we hadn’t travelled very far, but that was the real purpose of this expedition; to take the time to slow down; to really explore and enjoy this wilderness environment far from the busyness of daily life.

Ice chunks such as this were a very important part of the story of Petersburg.

As we turned into a narrow channel off Frederick Sound, a group of houses came into view and a small fishing boat passed us on its way out. Petersburg’s reason for existing is fishing!

The town was built here in this beautiful but isolated part of the wilderness for two reasons; an abundance of fish in the icy cold waters and an abundance of ice.  Before the days of large scale refrigeration, those ice chunks that come from the LeConte Glacier were used to keep the fish fresh until it could be canned or sent fresh to market.

Many houses have steep roofs because of the abundance of snow.

They are truly magnificent birds.

These eagles are not like the town scavengers we had seen in Juneau.

The waterfront at Petersburg is lined with fish processing sheds in which over 45.5 million kilos (100 million pd) of fish and shellfish are processed annually; canned, smoked and fresh. That’s a lot of fish from one very remote, small village!

The types of fish caught here include all five species of salmon; king (chinook); coho (silver); pink (humpy); sockeye (red); and chum (dog).  Other fish include halibut (a bottom feeder), ling cod, Pacific cod, herring and several species of rock fish. Shellfish such as Dungeness Crab, King Crab, Tanner, shrimp, scallops and clams are also caught in these cold waters.

Just reading that list makes my mouth water. We ate salmon cooked in a variety of ways of during our trip but, on this night in Petersburg, we were promised a fabulous feast of Dungeness crab.

P1130884

One of the sheds is adorned with a Viking Ship emblem, and for very good reason. This fishing village was founded more than 100 years ago by Norwegian fisherman, Peter Buschmann, after whom the village is named. He arrived in the area in the late 1890s; that’s after the start of the gold rush in the Juneau / Skagway areas. What this astute fisherman noted was the possibilities of this fine harbour tucked away off Frederick Sound with its abundance of fish, an abundance of ice floating by in the Sound and an abundance of timber for building. With other Scandinavian fishermen he set up a sawmill, a homestead, a dock and and a cannery. Today the village is known as ‘little Norway” and is still populated by people who are largely of Scandinavian origin.

Building and boat repairs are other important occupations in the village.

The boat on the right will certainly need repairs!

P1130879

Most fishing boats are kept in good condition. They need to be. Fishermen’s lives depend on the good maintenance of their boats. Not long before we arrived there, one boat that had not been properly repaired went down. Fortunately they had done a safety drill before they left port and their radio call brought the rescue helicopter to their aid. All of the men were winched to safety… the last man just as the boat sank from sight. But imagine what it was like in days past, when there was no rescue helicopter; a great many men were lost while fishing.

P1130880

The marina is filled with fishing boats of a variety of sizes and purposes. Three different kinds predominate; trollers, which bring fish in using lines with baited hooks; gilnetters, which use large curtain-like nets to entangle fish; and purse seiners, like the one we saw earlier in Frederick Sound, which let out a large net drawn in a circle before closing it at the bottom like a purse. Their goal is salmon swimming near the surface.

P1100471

Port of Petersburg © DY of jtdytravels; P1100471

There were plenty of smaller boats in the marina as well… the main way to get anywhere here is by water. In fact, apart from flying in, the only way to get anywhere is by water. A ferry system connects Petersburg to Juneau in the north and Ketchikan in the south.  Small ships, like ours, bring visitors to the area although none of the big cruise liners come here… the port is far too small.  Leisure fishermen and hikers arrive by sea plane or by daily commercial flights to Petersburg’s small airport. So although commercial fishing is the mainstay of the economy, tourism does play a part. Fishing tourism is particularly popular here in summer.

P1100565

“Sea Lion” docked in Petersburg © DY of jtdytravels; P1100565

Finally Captain Shaun brought the “Sea Lion” into our dock for the day and our DIBs were prepared for one of the afternoon’s excursion. While some chose to fly over the glaciers, others took a bike to explore the area. Others met with some of the old ‘sea salts’ of the town to learn more about life in this port. We chose the option of a walk and a plant hunt.

P1130874

For this walk, we first had to cross the bay in the DIBs and then climb that hill on the other side. Our goal was to walk up through various areas of forest until we reached a muskeg bog up on the plateau.  We were promised that we would find some very interesting plants… and we did.

  More of that walk in the next post.
