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.
You never know who you might meet when working out on the land. Kurt snapped this photo of a sweet little bunny in 2014.
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.
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.
While not as well camouflaged as the spruce grouse chicks, this toad does a pretty good job of keeping hidden.
We often post images of beautifully crafted tools such as the besant point from FcPu-11 or the siltstone knife from Buffalo Beach but not every tool we find is a “work of art.” This week’s photograph is of an “ugly” artifact we found in 2016 when undertaking an HRIA for Sundre Forest Products. The site was found on a terrace overlooking the confluence of two tributaries to the North Saskatchewan River. The artifact is a side-notched chert projectile point similar to the Prairie or Plains side-notched typology. The point is asymmetrical with one edge being a rounded convex shape and the other an undulating edge with an angular shoulder. The tip of the point is broken off which is common of the projectile points we find and is likely the reason the point was discarded. While aesthetics can add to the function of a projectile point this artifact demonstrates it was not necessary. The idea that it doesn’t matter how it looks as long as it works was alive in the past as much as it is today.
Digging in the forest we are always encountering tree roots. It’s a great test when you miss them all. Most days your shovel is sharp enough that you hardly notice the roots as the shovel blade slices through them. Sometimes you have layers of roots, which work as a group to form a wall. You can “smash” through them with a bit of effort, one root at a time. And then there are days like pictured here! Your shovel just won’t go through or you don’t have the energy to “smash” through them, so you have to break out the big guns! I like to carry a folding saw with me in my vest, so roots like these won’t get the better of me! Unfortunately these ones did. So I just dug around them.
