Sometimes working as an archaeologist involves getting up really early. After driving for an hour, this photo was taken in the morning of 2014 in the Martin Hills on the second last day of fieldwork.
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.
Who do you think won the race back to High Level?

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.
When working east of Nordegg in 2014 Vince found this little fawn. The spots on the fawn are for camouflage, to help him blend into his environment. These spots will last for the first 90-120 days of his life and will fade when he grows his warmer winter coat.
You never know who you might meet when working out on the land. Kurt snapped this photo of a sweet little bunny in 2014.
In recent months, news feeds have been erupting with stories of “Lost Maya Cities discovered using LiDAR”, “revealing the secrets of Stonehenge using LiDAR”, “LiDAR uncovers ancient city near Angkor Wat”, and the popularity of “space archaeologist” Sarah Parcak, but this technology is not limited to finding the remnants of “lost civilizations” in far reaching corners of the globe. LiDAR is used by archaeologists in Alberta to assist in the locating of potential archaeological sites that are threatened by development.
Light detection and ranging (LiDAR) is the process of mounting a laser on an aircraft and bouncing light pulses off the ground and measuring the time it takes for the laser to return. The process can take 2000-5000 measurements per second and makes the surface appear treeless, revealing surface features that cannot be seen using simple satellite imagery or aerial photos (Figure 1). However, using LiDAR to find archaeological sites in northern Alberta is not as easy as it can be in other parts of the world. LiDAR is great for identifying building structures, walls, and other features common of archaeological sites in other parts of the world. In northern Alberta these features are absent from Indigenous archaeological sites. To study the human history of northern Alberta prior to European contact we have to look at the landscape and identify landforms that would have been suitable for camping and hunting activities.
In the above images, the first image is a satellite image of a ridge where we found an archaeological site (Figure 2). With just satellite imagery the area appears to be predominantly flat which is not a good area to camp or hunt. This is because the area would be thought to be poorly drained and with limited visibility of the surrounding terrain. When using LiDAR imagery (Figure 3) we notice there is a complex of distinct hills and ridges that would be ideal for making camp.
This technology has revolutionized the process of finding archaeological sites in Alberta and is revealing more about the history of people in the boreal forest. The ability to pinpoint the best landforms without having to do extensive on-the-ground survey has greatly increased the inventory of sites found in northern Alberta. This benefits our clients who will pay less money for the survey of their developments and we can make more accurate predictions about site locations which allow them to modify their developments to avoid potential sites.
