In 2015 a two year poll was issued by Canadian Geographic for a new National Bird. In the end, our little Grey Jay took the lead, beating out the common loon, black-capped chickadee, snowy owl, and Canadian Goose. Although not officially recognized as the new National bird yet, it was selected as an avian representation of Canadians: its found in every province and territory, it’s friendly, and it’s very intelligent!
For the Cree, the Whiskey Jack, or Wisakedjak, is a shape-shifter, benevolent trickster, teacher, and messenger of the forest. There are many different stories about the Wisakedjak, but most of them have a moral. The appearance of the Wisakedjak in the morning is seen as a good omen, and is believed it warns people of nearby predators.
This boreal forest inhabitant is often spotted by Tree Time’s archaeology crews, and it has quickly become my favourite little bird. They are almost always seen traveling in a group of three: a monogamous pair and a juvenile from the previous year’s breeding season. The friendliest groups have always been found near areas people have made their hunting camps. In fact, the Whiskey Jack has figured out that people mean food. Given a few minutes, some of them may even eat out of your hand!
Whiskey Jacks stick around all winter too, even incubating their eggs as temperatures dip to -30°C. They store their food in crevices, under lichen, and even under conifer needles. They coat the food in a saliva, called bolus, which makes it sticky, ensuring the food doesn’t move until the Whiskey Jack returns. Unlike forgetful squirrels, these birds will remember exactly where they left their caches! Their food is a variety of arthropods (like spiders), small mammals, ticks, carrion, fungi, fruits, and seeds. The average life span is about 8 years, although the oldest recorded Whiskey Jack was 17 years old!
During our field seasons we find 100+ archaeological sites every year; however, not every site we find is flagged for avoidance. The decision of whether a site is avoided or approved for impact ultimately comes down to the Historic Resource Management Branch at Alberta Culture and Tourism’s approval of our recommendations. Our recommendations are based on the following criteria of site significance:
Multiple Component: The continued use of a landform throughout time increases the site significance. This can be represented by stone artifacts from different, distinct depths or in different layers. The most obvious multi-component sites are historic period sites (Post-European Contact) with an earlier Pre-European contact component. For example, we have found stone tools in tests conducted around the outside of a collapsed cabins.
Integrity: Sometimes we assess areas after they have been disturbed. We do this either to assess the level of impacts from the disturbance or protect sites from any further impacts (site preparation for tree planting, gravel pits, etc.). If we believe the site has been completely disturbed and the artifacts have lost their context, we will collect a representative sample of artifacts and recommend approval for the impacted area.

Datable Materials: The presence of organic material is necessary to determine how old the site is. This is quite rare in the boreal forests of Alberta because the acidic soils do not preserve things such as bone or wood. Often, the only datable material we find is charcoal which can be used for Carbon dating. The ability to date the site is important as archaeologists are still figuring out the evolution of tool use and the spread of people throughout Alberta.

Exotic Materials: The sites we find are typically scatters of tool stone such as quartzite and chert. These materials were local to the area, collected from stream beds by the past flintknappers. When we find something not native to Alberta, we consider the site to be of high significance. The presence of obsidian suggests trade or travel from areas with volcanoes. The presence of Knife River Flint suggests trade or travel from North Dakota.
Presence of tools or diagnostic materials: The majority of sites we find are simply areas where a stone tool was made. To find a tool is significant because it tells us what activities were happening at the site. These tools can include things such as: scrapers for scraping hides; knives for butchering animals; wedges or adzes for woodworking; or projectile points (e.g. arrowheads) used for hunting. Projectile points can also be diagnostic of certain groups (e.g. Clovis) or certain time periods (e.g. spears>darts>arrowheads).
Distinct intra-site activity areas or features: Sometimes we can find things that suggest a certain activity happened at a specific area of a site. This can be represented by what we call features which are non-portable representations of human activity. These can be such things as: post holes, hearths, or walls. We can also find distinct activity areas such as the flake scatter identified at the Brazeau Reservoir.
Uniqueness of the site in the surrounding area: We often find ourselves in areas of the province that have never had an archaeological survey before. I’ve found sites in areas of the province that we would describe as “the middle of nowhere.” Basically areas that are from major rivers or known travel corridors that were used by people in the past. To find a small scatter of flakes in an area without another site for another 20 km in any direction is more significant than finding another site in densely occupied areas such as the Fort McMurray region.
Site size: Our work is primarily concerned with determining how large the site is for purposes of avoidance by our clients. When we find very large sites these are considered of high significance due to the increased potential of finding anything listed above.
Back in September of 2017, I found what would probably be one of the coolest artifacts that I will ever find in my field survey career. My coworker Vince and I got up one fateful morning and set out on our four hour quad ride into one of the most beautiful areas in Northern Alberta: the Swan Hills. I have been working in the Swan Hills area for a few years now and every time I come back, I am always amazed by the broad vistas and pristine valleys that cut through this segment of the Alberta Foothills.
We were checking out a cutblock on the edge of a broad muskeg flat with a small stream. It was pretty swampy on the way in, but once we got closer to the stream, the land rose up into a nice, narrow little ridge that gave a good view over the stream. After walking around for a bit, Vince and I settled on a place to start digging. Normally, it takes a bit of time going through the screen before you can find the small stone flakes that we typically find. This time, I only had to flip over the root mat to see the top half of a stone blade stuck in the rootlets. A few seconds later, I pulled out the base of the same blade from the loose sediment, revealing a complete spear point buried only a few centimeters below the surface.
You can only imagine my excitement once I pulled this beautiful specimen out of the ground (I think I was making noises akin to Homer Simpson drooling over a doughnut). It is hard enough to find artifacts in the Boreal Forest, let alone to find a tool! My first thought as soon as I pulled it out was that I had found an Alberta Point. This is a type of projectile point that dates to around 9500 and 8000 years ago and is part of what is known as the Cody Complex. Alberta Points commonly have square stems that would have been hafted into a spear shaft, along with broad distinct shoulders and wider tapered blades. It seemed to be a good fit for the style of the point that I had found so I put Alberta Point in my notes and went about my day.
Back at the lab, I started flipping through my reference books. I began to realize that what I had found didn’t really fit with what we know about Alberta Points. The shoulders weren’t as square as other Alberta Points and the blade was a little too broad and less lance-like. I also noticed that the shape of the point closely resemble ones found at Hell Gap sites, dating to between 10,000 and 9,000 years ago (before the Alberta points and the Cody Complex). During this period, we see that First Nations ancestors were making similar large spear heads, but with a broader blade and slight, indistinct shoulders. So the spearhead that I found could also belong to this time period. However, the story doesn’t end there. To complicate matters more, there are also similar kinds of projectile points being made around Lake Athabasca in the northeast corner of the province. During the Early Taltheilei Phase (2600 to 1800 years ago), the caribou hunting people living on the shores of Lake Athabasca were making similar looking large spear and atlatl dart points. The point I found could fit into any one of these three possibilities.
So what kind of projectile point had I found? If we can identify the style, we can make inferences on the age and archaeological culture that was present at the site. Being able to place an age on a site is often difficult to do for Alberta sites, especially sites in the Boreal Forest. The lack of organic preservation at many sites means that radiocarbon dating is often not possible. Also, most archaeological sites in northern Alberta have very little stratigraphy, meaning that you will find 13,000 years of history in about 20 cm of soil. Even this artifact, which may be anywhere from over 10,000 to 2000 years old, was found only 5 cm below the surface. So if I were to determine how old this site was, I would need to be able to positively identify the type of projectile point that I had found. So what did I find? How was it made? Where did it come from? The answers to these questions can tell us about the people who made the artifact.
First off, the material. The point is made of fine-grained quartzite, a lithic raw material that was frequently used in Alberta all throughout history. There are a lot of advantages to working with quartzite. As a material it is very strong and durable, which means that the edge of the blade will hold longer than other materials like obsidian. This also means that it is extremely difficult to work with. When we try our hand at flintknapping today, we often start with obsidian, chert, or flint because these materials will fracture more easily and predictably than others. Pick up a raw quartzite cobble, and you’ll find that you be bruised from trying to crack it open.
Quartzite is also very common. Almost every stream, creek, and river valley is filled with a variety of quartzite cobbles. You don’t need to import it thousands of kilometers, unlike Knife River Flint or obsidian. Not all quartzite is the same quality, but there are well documented sources of high quality quartzite and sandstone throughout the province, like the top of the Grizzly Ridge by Swan Hills or in the Oil Sands around Fort McMurray.
In fact, this point is made from a type of quartzite that is commonly known as ‘Salt-and-Pepper’ because of the small black specks in the largely white stone. This material has been found all over Northern Alberta, but it is most commonly reported around Fort McMurray. While no source has been officially documented, archaeologists who work in the Oil Sands region often report seeing raw cobbles and boulders of ‘Salt-and-Pepper’ quartzite in the creeks flowing into the Athabasca River. It is very likely then that this point was made from a cobble that came from the Fort McMurray region. Whether the person who made the point carried from Northeastern Alberta or if it made its way by trade, we don’t know. However, it does show us the vast ancient networks that connected the First Nations across Alberta.
So we know where the raw material for the point came from, what about how it was made? What can the shape and design tell us about the people who made it? One way to study this is to look at the flake scars, the ridges and concavities left when pieces of quartzite were struck from the point. Most of the time with finished projectile point, or those that have reached the end of their life as a usable tool, we will see that the edges will be very uniform and straight, with small flake scars along the blade where the tool was resharpened. However, this artifact is very rough, the edges are irregular and chipped and the blade has large long flake scars covering the surface. Based on these traits, it appears that this point was unfinished, and looking at where the break is, it was likely broken when they were trying to make the blade thinner. This point is what would be called a ‘Preform’, a roughly worked projectile point that has not been attached to a haft yet. Preforms can take a variety of shapes and forms, but they often resemble the final point style.
So now that we understand that we are looking at an unfinished point, it better explains why the shape of the artifact does not perfectly match other Alberta points. However, that doesn’t help us to determine if it is an Alberta, Hell Gap, or Taltheilei projectile point. The implications of assigning the point one of these time periods is significant, because it would move the occupation of the site from a period where Giant Bison and Ice Age mammals roamed Alberta during the Hell Gap Phase, to an environment more similar to what we see today during the Taltheilei Phase. Personally, I think that the point from GfQa-5 is more similar to projectile points and preforms that have been dated to the Hell Gap period. The shape of the shoulders, base, and the blade all seem to better match the style of these points than Alberta Points, and the points found at Taltheilei sites tend to be smaller and narrower. A cache of similar looking spear points were found near Eaglesham in northwestern Alberta, and the archaeologists who studied these points concluded that they were likely unfinished Hell Gap points. It seems likely then that the spear point I found would fall into this time period. However, this is still based on very general characteristics, and it could still easily fit within all three of these categories. Until we have more information, and we excavate more archaeological sites, we are often left with our best guess.
Last year, while conducting survey with Brittany in a remote region of northern Alberta, I noticed some unusual scarring on a large spruce tree. Upon closer examination I realized the tree had been struck by lightning.
Usually when lightning hits a tree, one of three things may happen:
If the tree is wet on the outside, the electrical discharge may travel down the outside of the bark to ground and have little effect on the tree itself.
If the tree is not wet, the discharge may travel down the tree on the inside of the bark, which will result in scarring. In my experience, this will usually be one or more scars that revolve around the trunk of the tree as the discharge travels downwards.
If the tree is not wet, but is full of moisture, the moisture may be super heated and instantly turn into gas that quickly expands and causes an explosion. This may blow the bark off the tree, blow the top off the tree, or in some circumstances completely destroy the tree.
The tree that Brittany and I stumbled across had a considerable amount of damage due to the lightning strike. Yet, even though the tree had substantial bark scarring and its top blown completely off, it did not die and seemed to be in pretty good shape.
As rare as finding a lightning tree may seem, trees are actually struck by lightning very frequently. The Government of Canada reports that there is an average of 2 million cloud to ground lightning strikes per year in Canada, igniting approximately 45% of all our forest fires. These fires account for nearly 80% of the total forests burned annually. Although I wasn’t aware of these statistics until recently, my time working as a Forest Fire Fighter made me very aware of the frequency, since many of the fires we were called to fight were started by lightning. Even during a torrential downpour, lightning may still strike a spruce tree, causing a small fire to start at the base where it is sheltered by the branches. Days or even weeks later, when the temperature rises and the vegetation dries out, the fire may grow substantially in size. Suppression of these fires cost Canadian taxpayers a substantial amount of money. The Government of Canada has a whole section of their website dedicated to severe weather.
Taking refuge under a tree during a thunderstorm is very unwise. It may seem like a good place to keep dry during a sudden downpour, but it is actually one of the most unsafe places you could be. Indoors is always the safest place to be. However, if you are caught without shelter in a thunderstorm, the best place to be is in a low lying area such as a ditch. You might not stay dry, but you will be safe from lightning. Just make sure you watch out for flooding!
If you do happen to stumble across a lightning tree like Brittany and I did, you may want to take a little token for yourself (as long as it doesn’t harm the tree if it is still alive). Many people believe that the wood from a lightning tree will bring you good luck. Others believe that the power passed from the lightning to the tree, can then be passed on to whoever possesses its wood. Even if you are all full up on power and luck, you could always just keep the wood as a souvenir and reminder of the raw and devastating power of nature.
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.
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.
