The discoveries of Hearne & MacKenzie in the Canadian Arctic
In the late 18th century two transcontinental journeys, today little known, redefined the popular conception of the North American interior. These were the explorations of Samuel Hearne and Alexander MacKenzie, fur traders both, who, in search of profit and glory, separately penetrated the Canadian interior and in doing so became the first Europeans to see the Arctic Ocean from the shores of the North America. By traveling northward along an overland route from known territories, the work of these important explorers finally put an end to European ambitions for a Northwest Passage to the Pacific via inland waterways. Once news of their discoveries reached Europe, cartographers were quick to update their charts, filling in a significant part of the Canadian Northwest and redefining the cartographic perspective of the region.
Hearne's Trek to the Arctic
The first of these two journeys was made by Samuel Hearne. Hearne was a young Londoner who, after seven years at sea, transferred to the Hudson Bay Company. The vastly profitable Hudson Bay Company enjoyed a royal charter and for over 100 years maintained a near monopoly on the Canadian fur trade. Despite their astounding profits, or perhaps because of them, the Hudson Bay Company had long neglected the secondary provisions of their charter which involved exploring and developing the natural resources of their territory. Meanwhile, competition had emerged further west in the form of the rival North West Company. The North West Company had no royal charter, but was founded a gaggle of ambitious frontiersmen on the principal of exploration and exploitation. The NWC’s energetic exploration of northwestern America quickly opened a number of new regions to the fur trade. The HBC consequently began to notice a diminishment in their own profits. It was perhaps pressure from investors to keep competitive with the NWC that motivated the officers of the HBC to initiate an exploratory expedition of their own. Rather than compete directly with the NWC for fur profits, the HBC determined that it would leverage its vast financial reserves to diversify into whaling and minerals. Moses Norton, then the HBC’s chief factor at Prince of Wales Fort on the Hudson Bay had a near obsession, which he inherited from his father who held the same position, with legends of a copper mine far to the north from whence the indigenous Chipewyans often brought copper samples. Seeming the ideal target for diversification, the HBC thus sent one of its newest factors, the young trapper Samuel Hearne, on a quest for the mine, as well as for the whale rich Arctic Sea, in the unexplored north. In the process it was further hoped that Hearne would discover a waterway that might ultimately open a new Pacific trade route through the Northwest Passage.
Hearne, just 24 at the time, could not have been less prepared for the journey ahead. The young man had no experience in Arctic travel, had never undergone a similar journey, had no idea what to pack, and only a basic midshipman’s understanding of surveying and positioning. Hearne’s first attempt at this journey lasted but 30 days during which he was deserted and robbed by the local Indians he hired to guide him. His second attempt, though lasting nearly 8 months, also met with disaster when his quadrant, without which any proper surveying and positioning work is possible, was knocked to the ground and shattered by an unexpected gust of wind. Nonetheless, Hearne, ever persistent, prepared a third trip. This attempt, with some experience under his belt and a new trustworthy Indian guide in the form of the Indian chief Matonabbee, who had in fact traveled through and mapped out the region a decade earlier, proved that indeed “the third time is charmed”.
It was most likely Matonabbee whose able leadership and experience in the Arctic made the mission a success, but as with so many early explorations in the Americas, it is the handsome young European Hearne who ultimately received the lion’s share of credit. Between 1771 and 1772 Hearne and Matonabbee traveled steadily northwards, making maps and notations along the way, until they finally reached the Arctic Sea in July of 1771. This was doubtless Coronation Gulf though Hearne, through lack of experience using a sextant, mismapped it at 71 55 N, some 300 miles northward of his actual location. Nonetheless, the exploration was complete in that the Coppermine River as far as the Arctic had been explored. Hearn even found a gigantic ingot of pure copper with which to impress his superiors. Hearn, Matonabbee, and their entourage returned to their starting point, arriving at Prince of Wales Fort in June of 1772, having spent 19 months completing the mission.
In an act of greed and lethargy typical of large corporations even today, the Hudson Bay Company chose to suppress Hearne discoveries lest others take advantage of them first. It was not until 1782, when the Frenchman La Perouse captured Prince of Wales Fort, that information about Hearne’s achievements spread beyond the HBC. Perouse allowed Hearne, who was still stationed at Prince of Wales Fort, to take his maps and journals back to England. There Hearn compiled and published his accounts and maps.
MacKenzie's Trek to the Arctic
Meanwhile, further west, on the opposite shore of the Great Slave Lake, the NWC was sending out its own Arctic expedition. The North West Company was an amalgam of independent traders who made it their mission to explore and exploit fur trading opportunities in the American northwest. One of these was figures was the outrageous Peter Pond. Pond was an old school fur trader, that is to say: a hot head, a misanthrope, an adventurer, a liar, an egoist, an explorer, and an outright greedy bastard. He was the first to exploit the rich fur resources around Lake Athabasca and in the process he seems to have killed off most of his competition in the region. Nonetheless Pond began the work of mapping out the area around Lake Athabasca including the river systems in the vicinity of Great Slave Lake. From indigenous reports he was also able to sketch out the possible courses of several important rivers heading north and west of the Great Slave Lake.
Despite falling out with most of his peers, Pond seemed to have a fairly amicable and unlikely relationship with is second in command and apprentice in the fur trade, a young British nobleman named Alexander MacKenzie. It was possibly from the educated MacKenzie that Pond learned of the results of Cook’s third voyage in 1779. He was fascinated by references to Cook Inlet, in Alaska, which Cook did not explore fully and mistakenly took for a river estuary. Vastly underestimating the distance between Alaska and the Great Slave Lake, Pond immediately assumed that the great river leading westward from his lake could be none other than the same river that Cook discovered. Pond sketched out his vision of the region and of the river leading to the Pacific in 1787, only one year before he would retire, leaving his post and his legacy to his second, Alexander MacKenzie. A year later, before the results of MacKenzie’s own explorations around Great Slave Lake were known, Pond confessed his theories to friend Isaac Ogden, who wrote “There can be no doubt but the source of Cook’s River is now fully discovered and known.”
MacKenzie set out, in 1789, to prove Pond’s theory and finally discover the inland Northwest Passage. Sadly and to his dismay, the river identified by Pond heading westward from Great Slave Lake turned sharply north. MacKenzie and his team, fighting against the current, powered their canoes upward along the river, sometimes traveling 17 hours a day, before ultimately reaching a tidewater which they associated with the Arctic Ocean. MacKenzie named the river Dissapointment, but it was later renamed the MacKenzie River in his honor. Though MacKenzie considered his voyage a failure it was quickly publicized in Europe, reaching the public within a year of Hearne’s journals.
MacKenzie’s expedition had very much the same results as Hearne’s but from the opposite direction. Both proved that no watery Northwest Passage existed through North America’s inland river systems. The journals of Hearne and MacKenzie filled in many of the blank spaces in the American west and would be the most significant accountings of their respective regions for the subsequent 100 years. It was not until the mid to late 19th century that explorers and cartographers were able to reconcile these important explorations with new data to develop a full map of the region.

Of the two explorers, both had distinguished follow-up careers. Hearne retired from exploration and became an important and eccentric figure in the Hudson Bay Company. He was later mentioned in the works of Darwin and was known for collaborating with naturalists in an effort to further science through his discoveries. He also, it is said, inspired Coleridge’s Ancient Mariner. MacKenzie continued to search for a route to the Pacific and ultimately became the first European to cross North America north of Mexico and reach the Pacific.
