Stone tools, Bugs, and the Boreal Forest: Adventures in Northern Archaeology

When people think of archaeology in Alberta they might picture buffalo jumps, rock art, or medicine wheels. These are dramatic types of sites on the prairies but what about the north? Alberta’s boreal forest has a unique record and requires a unique breed of archaeologist to find it. This blog is a small window to archaeological work in the northern half of the province and some of the interesting archaeological sites hiding in our forests.

Boreal Breed

Archaeologists working in northern Alberta brave bugs, blowdown (piles of fallen trees stacked like a cruel game of KerPlunk) and a range of conditions from blistering hot to bitterly cold. Forests are quite good at concealing sites so archaeologists dig hundreds of small shovel tests to find them. Most archaeology in the ‘Green Zone’ (typically forested Crown Land) happens in advance of forestry, oil and gas activity, gravel operations, and construction of transmission or road corridors. The hard work and skill of consulting archaeologists has resulted in over 8000 archaeological sites in the Green Zone.

Roughly 8000 sites have been found in Alberta’s boreal forest.

The Nature of Northern Sites

Most of the successful shovel tests yield small collections of stone debris from pre-contact human tool making. Sites in the north are typically smaller than on the plains. Why? Pre-contact people in the north were generally more mobile and lived in smaller groups; southern bison herds supported bigger groups that stayed in one spot for longer periods, which produced bigger collections of artifacts. Archaeological visibility is also a factor. Prairie landforms are often easier to locate and interpret while artifacts, bones, or stone features on the surface can help guide archaeologists to productive areas under the ground. Not so in the north. Hot spots for artifacts are often harder to access, are covered in vegetation and dense roots, and are challenging to interpret (e.g., ‘how has this terrace changed over thousands of years’).
