In south-west Alberta, the remains of marked trails and an aboriginal camp, and a tumulus where vast quantities of buffalo (American Bison) skeletons can still be found, are evidence of a custom practised by aboriginal peoples of the North American plains for nearly 6,000 years. Using their excellent knowledge of the topography and of buffalo behaviour, they killed their prey by chasing them over a precipice; the carcasses were later carved up in the camp below.

Brief synthesis

The significance of the landscape of lies in its historical, archaeological and scientific interest. The deep, undisturbed layers of animal bones (largely American Bison) represent nearly 6,000 years of continuous occupation with one lengthy period of unexplained interrupted hunting. This landscape is an outstanding example of subsistence hunting that continued into the late 19th century and which still forms part of the ‘traditional knowledge base' of the Plains nations. It throws valuable light on the way of life and practices of traditional hunting cultures elsewhere in the world.

is located in southern Alberta, Canada, where the foothills of the Rocky Mountains meet the Great Plains. It is the best preserved example of the communal hunting techniques and of the way of life of the Plains people based on the vast herds of bison that existed in North America for more than five millennia. A remarkable testimony of pre-European contact life in North America, this bison jump bears witness to a sophisticated custom practiced by Indigenous people of the North American plains. These people, drawing on their excellent understanding of bison behaviour and topography, used natural barriers such as coulees, depressions and hills to funnel these animals into drive lanes that ended at a precipice, over which the bison were stampeded. The animals' carcasses were then butchered in a camp set up below the cliff to provide food and the materials for clothing, tools and dwellings. The development of complex social and technological systems to systematically and repeatedly harvest the herds in a communal hunt also nourished spiritual interests. is the most outstanding of the surviving bison jumps in the Americas in use from approximately 5,800 years BP until AD 1850. On this grassy, windswept 4,000-ha landscape can be seen the drive lanes that led the bison toward the jump (including the remains of stone markers used to direct the bison toward the cliff), the 10-m-high cliff face that served as the actual jump, the foot of the cliff where numerous undisturbed stratified layers of bone and cultural deposits are found, and the area encompassing the many butchering camps established through the millennia.

Criterion (vi):

is one of the oldest, most extensive and best preserved sites that illustrate communal hunting techniques and of the way of life of Plains people who, for more than five millennia, subsisted on the vast herds of bison that existed in North America.

Integrity

The 4,000-ha property encompasses all the elements necessary to understand the communal hunting technique that is the basis for its Outstanding Universal Value, including numerous undisturbed stratified layers of bone and cultural deposits, drive lanes, the cliff face and the butchering camps. Its boundaries thus adequately ensure the complete representation of the features and processes that convey the property's significance. The property is not at risk of degradation and does not suffer from adverse effects of development and/or neglect. There is no buffer zone.

Authenticity

is an exceptionally well-preserved landscape that illustrates the Indigenous tradition relating to bison hunting. In terms of setting and materials, the extensive landscape features include the gathering basin and archaeological features such as the rock cairns that define the borders of the extensive drive lanes. Since 1960, the property has been the object of systematic archaeological excavations that have enriched knowledge about the pre-European-contact era. This information transformed previously held theories on the use of game for food, clothing and shelter by the Plains people.

A potential threat to the authenticity of the property is the increase in the erosion of the cliff and pathways with use over time and with the extreme weather patterns seen in recent years. An increasing number of visitors at has the potential to create pressures on the property. Since inscription, a visitor interpretation centre has been built into the cliff side and access to the property has been restricted in order to control visitor impacts and to interpret the property's associated values more effectively. Where required, archaeologists have also surveyed and sampled pathways, roadways and parking structures to ensure they are clear of any significant cultural materials.

Protection and management requirements

is safeguarded by several levels of protection from the federal, provincial and local governments. It is commemorated by the Government of Canada as a National Historic Site (1968). The Province of Alberta has also designated it a Provincial Historic Resource (1979), thereby protecting the property under the Alberta Historical Resources Act. This Act includes severe penalties for any action that has an adverse physical or visual effect on the resources associated with the reasons for the property's designation, and provides for the administration of archaeological resources through its Archaeological Research Permit Regulation. is also included in Alberta's Special Places 2000 program in order to afford it another safeguard through monitored use. Alberta's Municipal Government Act provides additional protection for the property by establishing Direct Control Zoning that can consider heritage conservation in land use planning at the municipal level in the province. As a result, activities such as the development of industry in the surrounding titled lands, including windmills, electrical lines, and mines, are restricted. The use of land for ranching has had minimal impact on the archaeological resource.

The central 640 acres (S6-9-27-W4) of the property is owned and managed by the Government of the Province of Alberta as a provincial historic site. The remainder of the 4,000 hectares is a mix of provincial Crown land leased to local ranchers and private deeded land owned by those same local ranchers, along with a strip of land along the southern border of the inscribed area that crosses over the northern border of the Piikani Nation Reserve.

Leasehold Crown Lands adjacent to the provincial historic site do have additional restrictions in place under provincial law to provide for strict controls on physical and visual impacts. For example, a fence must be placed in such a way as to be unobtrusive to the viewscape, by following land contours in coulee bottoms. The private deeded land within the inscribed area and the agreements with those landowners are not formalized in all cases.

These stakeholders were directly consulted in the site development process at the invitation of the Province of Alberta. Ongoing community consultations may at times include a Minister's Advisory Committee comprised of the primary regional stakeholders.

The site is developed and managed by the Province of Alberta in consultation with the local Blackfoot-speaking First Nations. Blackfoot-speaking interpretive and education guides are engaged exclusively to interpret the property and their culture. While there is no Management Plan in place for the property, there is a Development Plan and Interpretation Plan, in addition to which the site is managed as an Alberta Culture, Historic Sites and Museums Branch Interpretive Centre.

Sustaining the Outstanding Universal Value of the property over time will require monitoring the erosion of the cliff and pathways, with the intent of preventing further erosion of land under stress, either by wind or water; and ensuring the number of visitors does not have a negative impact on the property's value, authenticity or integrity.
