Geocache Description:

You are standing at a continental divide. Water from here flows in two different directions. Read the plague to learn how this divide shaped the boundary of our nation with Canada.



Hudson Bay (French: baie d'Hudson) is a large (1.23 million km²), relatively shallow body of water in northeastern Canada. It drains a very large area that includes parts of Ontario, Quebec, Saskatchewan, Alberta, most of Manitoba, parts of North Dakota and Minnesota, and the southeastern area of Nunavut. A smaller offshoot of the bay, James Bay, lies to the south. The IHO, in its Special Publication 23, Limits of Oceans and Seas, fourth edition, lists Hudson Bay as part of the Arctic Ocean. On the east it is connected with the Atlantic Ocean by Hudson Strait, and on the north with the rest of the Arctic Ocean by Foxe Basin (which is not considered part of the bay) and Fury and Hecla Strait. Geographic coordinates: 78° to 95° W, 51° to 70° N.

Due to a change in naming conventions, Hudson's Bay is now correctly called Hudson Bay. As a result, both the body of water and the company are often misnamed Hudson Bay has a salinity that is lower than the world ocean on average. This is caused mainly by the low rate of evaporation (the bay is ice-covered for much of the year), the large volume of terrestrial runoff entering the bay (about 700 km³ annually; the Hudson Bay watershed covers much of Canada, with many rivers and streams discharging into the bay), and the limited connection with the larger Atlantic Ocean (and its higher salinity). The annual freeze-up and thaw of sea ice significantly alters the salinity of the surface layer, representing roughly three years' worth of river inflow.

The western shores of the bay are a lowland known as the "Hudson Bay Lowlands" which covers 324,000 km². The area is drained by a large number of rivers and has formed a characteristic vegetation known as muskeg. Much of the landform has been shaped by the actions of glaciers and the shrinkage of the bay over long periods of time. Signs of numerous former beachfronts can be seen far inland from the current shore. A large portion of the lowlands in the province of Ontario is part of the Polar Bear Provincial Park, and a similar portion of the lowlands in Manitoba is contained in Wapusk National Park.

In contrast, most of the eastern shores (the Quebec portion) form the western edge of the Canadian Shield in Quebec. The area is rocky and hilly. Its vegetation is typically boreal forest, and to the north, tundra.

Measured by shoreline, Hudson Bay is the largest bay in the world (the largest in area being the Bay of Bengal). There are many islands in Hudson Bay, mostly near the eastern coast. All are part of the territory Nunavut. One group of islands, with a reputable name, is the Belcher Islands. Another group includes the Ottawa Islands.

When Earth's gravitational field was mapped starting in the 1960s a large region of below-average gravity was detected in the Hudson Bay region. This was initially thought to be a result of the crust still being depressed from the weight of the Laurentide ice sheet during the most recent Ice Age, but more detailed observations taken by the GRACE satellite suggest that this effect cannot account for the entirety of the gravitational anomaly. It is thought that convection in the underlying mantle may be contributing.

Supposedly there are large deposits of iron ore under the bay which affect magnetic fields and compasses.

Early History of Hudson Bay Company

The Governor and Company of Adventurers of England trading into Hudson's Bay was incorporated on May 2, 1670, with a Royal Charter from King Charles II. The charter granted the company a monopoly over the Indian Trade, especially the fur trade, in the region watered by all rivers and streams flowing into Hudson Bay in northern Canada, an area known as Rupert's Land after the first director of the Company, Prince Rupert of the Rhine, a first cousin of Charles. This region constitutes 1.5 million square miles (3.9 million km²) in the drainage basin of Hudson Bay, comprising over one third the area of modern-day Canada and stretching into the north central United States, but the specific boundaries were unknown at the time.

The company founded its first headquarters at Fort Nelson at the mouth of the Nelson River in present-day northeastern Manitoba. The location afforded convenient access to the fort from the vast interior waterway systems of the Saskatchewan and Red rivers. Other posts were quickly established around the southern edge of Hudson Bay in Manitoba and present-day Ontario and Quebec. Called "factories" (because the "factor", i.e. a person acting as a mercantile agent and frequently specializing in one or a small number of commodities, did business from there), these posts operated in the manner of the Dutch fur trading operations in New Netherland.

During the spring and summer, First Nations traders, who did the vast majority of the actual trapping, travelled by canoe and were received at the fort to sell their pelts. In exchange they typically received metal tools and hunting gear, often imported by the company from Germany, the centre of inexpensive manufacturing in that era. The early coastal factory model contrasted with the system of the French, who established an extensive system of inland posts and sent traders to live among the tribes of the region. After war broke out in Europe between France and England in the 1680s, the two nations regularly sent expeditions to raid and capture each other's fur trading posts. In March 1686, the French sent a raiding party under Chevalier des Troyes over 1300 km (800 miles) to capture the company's posts along James Bay. The French appointed Pierre Le Moyne d'Iberville, who had shown extreme heroism during the raids, as commander of the company's captured posts. In 1697, d'Iberville commanded a French naval raid on the company's headquarters at York Factory. On the way to the fort, he defeated three ships of the Royal Navy in the Battle of the Bay, the largest naval battle in the history of the North American Arctic. D'Iberville's depleted French force captured York Factory by a ruse in which they laid siege to fort while pretending to be a much larger army. York Factory changed hands several times in the next decade. It was finally ceded permanently to what was by then the Kingdom of Great Britain (following the union of Scotland and England in 1707) in the 1713 Treaty of Utrecht. After the treaty, the company rebuilt York Factory as a brick star fort at the mouth of the nearby Hayes River, its present location.
