Prior to this trip we had all done a considerable amount of research about the Yukon River ranging from topics such as the Klondike Gold Rush, Yukon wildlife, and places of interest. I also researched the fish found in the waters of the Yukon River. I was researching fish because I hoped to gain an advantage to help supplement our meals by catching delicious fresh fish. Looking back on the week I am really glad that Dave and Amy packed a sufficient amount of food for us. The one fish I was anxiously awaiting to see was the Chinook salmon. I was waiting to see the river start to bubble and to turn red indicating that that our journey had crossed paths with the great salmon migration.
The Yukon River is associated with the longest salmon migration in the world. From mid July through September Chinook salmon start their 60 day, 2,000 mile journey up the river from the Bering Sea to spawn in the gravel riverbeds in the tributaries of the Yukon River. The female salmon will dig nest called redds, and lay anywhere from 3,000 to 14,000 eggs in the fast moving water. What makes this migration so fascinating to me is that during the spawning period salmon do not eat while on the entire journey and eventually dying after laying one’s eggs.
Chinook salmon which are also known as Blackmouth, Tyee, King, and Spring salmon begin their lives in freshwater and then migrate to the ocean to find food and grow. In North America, Chinook salmon have
been known to range from Monterey Bay, California to the Chukchi Sea near Alaska. They are very large bodied fish with a bluish-green coloration that fades to a silvery color around the lateral line to
eventually diminishing to a white belly. During the spawning period the salmon turn a reddish color that varies in shade due to the age and location of the fish during migration.
The First Nation communities that reside along the shores of the river depend on the salmon migration for a source of food during the long cold winter months. We saw many fish camps with people that were waiting with empty gill nets and drying racks. We were able to stop and see one camp that had caught nearly 70 salmon. Fresh salmon eggs were laid out on drying racks made of chicken wire and many filets of salmon hung on racks to cure for preservation. The First nation Communities are not the only communities effected by the late and low populated salmon run this year. NOAA (National Oceanic and Atmospheric Administration) has declared a commercial “fishing failure” in the Alaskan’s Yukon River due to the low number of returning salmon. Chinook salmon is the state fish of Alaska and due to some environmental changes their numbers are diminishing. This has had catastrophic effects on the fish communities that make a living fishing during the salmon migration.
I did not get to see any salmon in the process of their own migration. I hope that sufficient research can be done to explain why the populations of salmon of diminishing and we, as humans, can make better sustainable choices when it comes to the food that we eat.

Success story on the Columbia River

During stage 1 we will kayak 1,400 miles from Seattle, Washington to Skagway, Alaska. The Pacific Northwest is home to a wide range of aquatic and terrestrial animals. We will be studying whales and other marine mammals, kelp forests, salmon, and many other species.
The Pacific Northwest is home to a variety of large land mammals including Grizzly Bears, and Black Bears. Above and below the surface we are sure to find plenty of things to learn about. Many of these large mammals need large undeveloped spaces to thrive and the roadless sections of British Columbia and Alaska provide the perfect habitat.
From Skagway, Alaska we will hike over the Chilkoot Pass in the footsteps of thousands of gold seekers who struggled across the pass to reach the Klondike. Many of artifacts remain from those early days, and we will follow their path all the way to Dawson City along the mighty Yukon River.
From Bennet Lake on the eastern side of the Chilkoot Pass we will canoe through a chain of lakes that form the headwaters of the Yukon River past White Horse and down the swift flowing Yukon River to Dawson City.
From Dawson we will hike 100 miles through the mountains to the headwaters of the Blackstone River. The Blackstone flows into the Peel River, which flows in the McKenzie River, which will lead us to the Arctic Ocean. The rivers flowing through these rugged mountains as some of the most pristine wild rivers in North America, with hundreds of miles of flowing waterways between towns or roads.
After over 2,600 miles of paddling and hiking we hope to reach the Arctic Ocean before freeze up. We will spend the month of October,2010 training our dogs, and learning about native life in the Arctic. In November we will head south along the McKenzie River by dog team, crossing 1,800 miles of frozen wilderness. There are many remote native communities along our way and we are sure to learn a lot from the people we encounter.
When the ice melts in the Spring of 2011 we will transition from dogsled to canoe and paddle 2,300 miles along the historic travel and trade route pioneered by Alexander McKenzie, Samuel Hearne, and other Canadian Explorers in the 1700's. We will finish this stage of our journey in the fall of 2011 by completing the 8 1/2 mile Grand Portage which will lead us to the rock shore of Lake Superior.
After spending the winter giving presentations and making final preparations we will begin 4,800 mile kayak journey from Grand Portage, Minnesota to Key West, Florida. The first 2,200 miles will take us through the Great Lakes and out the Saint Lawrence Seaway.
During the final stage of our journey we will kayak the length of the Atlantic Coast from the Saint Lawrence Seaway to Key West, Florida. We will be following the seasonal whale migration from the Bay of Fundy in Maine to the warm clear waters of the Gulf of Mexico. Along the way we will visit cities large and small, and study a variety of ecosystems and environmental topics. We also plan to take side trips into the cyprus swamps and Everglades National Park looking for Alligators, birds, and other critters.
