Endscraper

This is a tool used to peel away unwanted matter from an object. It was often used to prepare animal hides and would have been attached to a handle made from either wood, bone or antler. There are different types of scrapers in Alberta including sidescrapers, endscrapers, and thumbnail scrapers. Scrapers are one of the most common types of formed tools we find in Alberta. Pictured here is an endscraper that we collected during the summer of 2017.

 

Wedge

This little guy is a wedge, or sometime as it is sometimes known as its french name, pieces esquilles. These tools are thought to have been used to split organic materials like wood and bone, much like an ancient stone chisel. One of the sharp sides of the wedge would be placed against the material that you wanted to split, and you would hammer the other end with a stone to drive the wedge through it. Since this little tool would literally be caught between a rock and a hard place, using a wedge would often create bipolar flake scars. You will also often see crushing and lots of hinge fractures on the tops and bottoms of these tools, where the edges are being crushed against the hammerstone and the material being split. As a result, wedges often have a short and squat rectangular body shape.

This particular specimen is made from a very coarse grained quartzite. Based on the reddish hue of the stone, it may have even been heat treated to improve the quality of the material. It was found near Wabasca-Desmarais, on a high ridge that overlooked a broad stream valley.

Expedient Tool

An expedient tool is an object that can be made quickly and easily with little or no production effort. This is a retouched flake we collected during the summer of 2016. The red arrow is pointing to where the flake has been retouched.

Tree Throw

We often inspect tree throws for artifacts. A tree throw is a bowl shaped depression that is often created when a large tree has blown over or has had its stump pulled out. This tears out soil with it creating a surface exposure for us to inspect.

This tree throw at FbPv-12 contained hundreds of flakes. The red arrow is pointing to one.

Isolated Find

This biface came from a site that was classified as an isolated find. This term means that only one artifact was observed and/or collected.

This biface was the only artifact recovered from IcQa-23 near Fort Vermilion.

Auger

A bucket auger can be a useful tool to test for buried paleosols. An auger is a tool used for boring holes in the ground. This one has a cross handles and a rotating shaft with a bucket on the end. The bucket is placed on the ground and then the cross handles are turned. When the archaeologist is done, the auger is pulled up along with the soil that was in the bucket.
