Athabasca Basin

From its headwaters in Jasper National Park, Alberta’s Athabasca River travels
some 1,500 miles northeastward across the province, its waters ultimately flow-
ing into Lake Athabasca. The river drains a vast region—roughly 159,000 square
kilometres—along the southern margin of Canada’s Boreal Plains ecozone,
which encompasses much of central and northern Alberta. In contrast to the
grasslands further south, the Boreal Plains ecozone is heavily forested, forming
part of Canada’s more broadly defined boreal forest.1 The Lower Athabasca
basin lies wholly within the Boreal Plains ecozone, and, although some notable
uplands occur, the area consists for the most part of glacial lake bed or till plain
on which large tracts of muskeg and fen have developed between areas of
modest elevation. Major fish-bearing lakes—Lake Athabasca and Lac La Biche—
are situated along its northern and southwestern margins, respectively, and
smaller lakes and ponds are scattered throughout the area. As with similar
regions across the northern hemisphere, food resources are relatively meagre
and widely distributed, traditionally supporting only comparatively small popu-
lations of hunter-gatherers. With the exception of the access afforded by the
river, travel throughout the region is difficult.
Although the Lower Athabasca basin features a broad spectrum of natural
resources, two classes of resource have proved to be of major commercial inter-
est to outsiders. In 1778, explorer and trader Peter Pond arrived in the Athabasca
region and established a fur trade post, thereby inaugurating an activity that
would serve as the basis of the region’s commercial economy for a century and a

half. Pond noted the occurrence of a fluid tar-like substance (Stringham 2012, 21),
which explorer and trader Alexander Mackenzie described in his journal a
decade later, in 1788:
At about 24 miles from the fork [of the Athabasca and Clearwater
Rivers] are some bituminous fountains into which a pole of 20 feet
long may be inserted without the least resistance. The bitumen is
in a fluid state and when mixed with gum, the resinous substance
collected from the spruce fir, it serves to gum the Indians’ canoes.
In its heated state it emits a smell like that of sea coal. (Mackenzie
1970, 129)
As Mackenzie noted, the Athabasca River and some of its tributaries had cut
down through the surrounding bedrock, exposing bitumen along river banks in
various locations to the north of modern Fort McMurray.
Aboriginal people had known of these bitumen deposits for millennia. Long
before Pond arrived in the oil sands area, a Cree chief, known in historical rec-
ords as “the Swan,” had brought them to the attention of the Hudson’s Bay
Company traders. In 1715, the Swan visited York Factory, where he described the
Athabasca region, telling of a river on whose banks could be found “Gum or
pitch.” Four years later, the Swan returned to York Factory, bearing a sample of
“that Gum or pitch that flows out of the Banks of that River,” which he presented
to HBC governor Henry Kelsey.2 Other resources in the region were, however, of
greater value to the indigenous inhabitants. As the chapters in this volume dem-
onstrate, a conjunction of natural and human factors has resulted in an unusually
rich record of landscape development and human use that makes the Lower
Athabasca basin exceptionally valuable for understanding the early history of
Canada’s north. The archaeological record currently being revealed represents
perhaps the most intense pattern of prehistoric human landscape use yet identi-
fied in Canada’s boreal forest region.3
Investigation into the character, extent, and value of Alberta’s bitumen resour-
ces began in the 1890s. Early in the twentieth century, in an account of an exped-
ition to the Mackenzie basin in connection with Treaty 8 (signed in 1899), Charles
Mair wrote: “The tar, whatever it may be otherwise, is a fuel, and burned in our
camp-fires like coal. That this region is stored with a substance of great economic
value is beyond all doubt, and, when the hour of development comes, it will, I
believe, prove to be one of the wonders of Northern Canada” (1908, 121). Mair’s
instinct would prove to be correct. Research was accelerated by the demand for
fuel during both world wars, and in the early 1960s a commercially viable process
