Projectile Point

Projectile points come in many shapes and sizes ranging from large paleolithic spear points to small protohistoric arrow heads to even smaller “toy arrow heads”. This artifact type is a stone that has been shaped using flint knapping techniques to create a sharp triangular and aerodynamic tip that is attached to a wooden shaft that can be propelled through the air by throwing by hand, atlatl, or bow, to hunt game. This is an important artifact type as over time the styles of points changed allowing us to use the style to estimate the time period a site was occupied.  This particular point is a Besant style dart point, which dates to approximately 2,500 -1,350 BP.


The context of an artifact is extremely important to archaeologists. The context of an artifact means the precise location of the artifact and it’s association with other artifacts and landscape features. This helps us determine such things as the relationships between artifacts on a site, it’s position in time and space, and even how it is related to different archaeological sites.

Below is a picture from a site near the Brazeau Reservoir, Alberta. The lithic scatter pictured below shows the flakes in their original context. The whole scatter is in a semi circle shape outlined in red. The positions of the flakes indicate that someone likely sat near the red circle. They then flint knapped purple quartzite which went in the direction of the purple arrow. They then shifted their body and began to flint knap a grey-blue quartzite that went in the direction of the blue arrow.

This is just a small portion of the site, so when we start to put together this information with other information about the site we begin to get a greater understanding of what happened, such as where specific activities took place and even what was going on in the area at that time.


An atlatl is a throwing stick with a small hook used to throw darts (projectiles). It allowed the hunter or warrior to create more leverage to increase the speed and distance of the dart. This weapon was used throughout North America including Alberta, approximately between 7,500 and 1,350 B.P.

A spokeshave is a type of formed tool that was used to scrape and/or smooth wooden shafts or handles such as on spears, darts and arrows. It is typically identified by the inward curving edge. This edge typically has small flakes removed from use or from shaping it into the curve prior to use.

Knapping / Flintknapping

The process of creating stone tools through lithic reduction (by removing stone chips).  A hammer (such as a stone or antler) is used to strike the core rock in order to remove smaller pieces.  The core is either shaped into a specific tool, like a biface, or the flakes that have been taken off are used or shaped into something specific, like a projectile point.

Surface Exposure

Surface exposures are areas where there is no vegetation and the mineral soils are visible. These can occur naturally (areas of slumping, beaches, blow-out, or other natural erosional processes), or be caused by human activity (ATV trails, furrows created for site prep and skid trails just to name a few). Surface exposures can be great for covering a lot of ground during survey.


A biface is a stone tool that has flakes removed from both sides. It can be used as a knife, scraper, or further worked into a more recognizable tool. The typical biface shape is an oval with slightly pointed ends. The biface on the left was found near Fort Vermilion in 2016.
