I have been working in cultural heritage management for five years and have also worked in academic institutions.
I am a permit-status archaeologist in Alberta but also have extensive experience in British Columbia. I have undertaken all stages of assessment on a variety of site types and for a range of development projects (forestry, rail, roads, and research).
In addition to my experience in the field, I have a background in Geographic Information Systems (GIS) which was the main source of analysis for my thesis "An Analysis of Site Selection Behaviours in the Prince Rupert Harbour Area." This is one of the strengths I bring to the Tree Time Services team as I have contributed to the development of archaeological predictive models for our clients.
Back in 2015 I was dropped off by a helicopter in the middle of a large muskeg to assess a cutblock for Alberta-Pacific Forest Industries. After trudging my way through the swamp to the cutblock, I found a very prominent but small hill. I put my shovel in the ground and I found one large, beautiful flake. I tested out the rest of the landform but found nothing else. I flagged the site for avoidance by harvesters and made my way back through the muskeg to be picked up by the helicopter.
When I got there I told the pilot that I found a site. He responded “Really? This is the middle of nowhere. Why would anyone be out here?” To which I replied, “People were everywhere, man.” The pilot was skeptical and asked to see what I found. He said, “That’s just a rock that was broken by your shovel.” I responded by saying, “I can give you eight reasons why this is a legitimate artifact…”
The above artifact is the “textbook flake” that I found that day. It has all the features that we typically look for in determining if it is natural or a rock that was broken by a human in the past. These features are:
1. Bulb of percussion: A bulb that forms directly below where the hammerstone struck the core. This is what causes the flake to be popped from the core. If a rock is broken by heating or freeze-thaw this bulb will not be present.
2. Platform: The flat area where the flintknapper would strike the core to pop the flake off. These areas are sometimes prepped to be struck by rubbing the hammerstone on the edge to strengthen the edge and remove any micro-fractures that may cause the rock to break in an unintended way.
3. Percussion waves: Caused by the force travelling through the flake.
4. Eraillure Scar: Small flake scar on the ventral surface of the flake which is the result of the rebounding force from the percussive force.
5. Termination: This flake has a feather termination. This is a perfect detachment of a flake from a core. Desirable because the end of the flake is sharp without need to resharpen or retouch. This means that the flake is a ready tool that can be used to cut or scrape. Other types of terminations include: hinge, step, and overshot terminations. These are usually an error by the knapper or flaws in the core.
6. Flake Scars: Areas on the dorsal surface of the flake where flakes were knocked off during earlier stages of tool making process. The coincidence of these being present on a naturally broken rock are impossible.
7. Material: The material of this flake is a fine grained chert. This is not a rock that would naturally be found in this immediate area. There were also no other rocks present in the shovel test or any of the other shovel tests that were dug that day.
8. Context: Sometimes when rocks are crushed by heavy equipment they can break in a similar fashion but this was found pre-disturbance. Additionally, the force from me putting my shovel into the ground could never possibly break a rock in this fashion. I am not that strong.
It is not often that we have all of these flake features present. Sometimes if a flake is broken we might not be able to see the bulb and platform or the termination. We usually try to find at least two of these features to call something an artifact. To convince a non-archaeologist a flake is genuine you might need all these features present. I feel like I convinced the pilot that this was a real artifact but I think he only responded by saying “interesting.”
In the summer of 2016, this tool was identified while inspecting the exposures along an in-block road for Boucher Bros Lumber. It is likely the bottom portion of a biface that broke during manufacture or use. It is made from Peace River Chert, a material common to the Peace River region.
One of the most common questions that I get asked is what is the coolest thing I have ever found. My default answer is this censer fragment that my excavation team unearthed back in 2009 as part of the Trent University field school in Belize, at the Minanha site.
My team was working on the excavation of a house platform. The house platform was part of a small complex of households near a ceremonial and political centre. the site was abandoned around 1000 years ago at the end of the Classic era of the Maya civilization.
One of the first things found during the excavation was a small cylinder seal next to the large tree root (pictured above). Unfortunately, I didn’t get a picture of the artifact but I still have my notes from the field school and a quick sketch that I did.
As we continued to excavate through different occupation layers, we came upon an assemblage of broken pottery sherds. We were careful to map each artifact before we removed them from their context (as indicated by the nails at each corner of the artifacts). We could see there were holes in the ceramics but had no idea of what was waiting once we turned it over.
When the sherd with the holes was turned over, the entire team got really excited and gathered around while the professor, Gyles Iannone, explained what we found. The artifact was part of a large incense burner. When incense was burned within the vessel, the smoke would come out the holes in the censer. The smoke flowing out of the mouth likely created a very stunning effect. After the field school was completed, the graduate students catalogued the artifacts and re-assembled the censer (pictured below).
While we always prefer to survey areas prior to any impacts, the identification of artifacts in post-impact contexts can be easier because of large areas of exposed sediments. Instead of targeted shovel tests that excavate a very small percentage of a high potential area, we can potentially see everything that is under the ground. However, the context of anything we find must be taken into account because heavy equipment can break cobbles and create things that look very similar to lithic debitage. If we find an artifact in the track of heavy machinery we need to be careful we are not misidentifying what we call a “tractorfact.”
In spring of 2017, we surveyed a proposed Associated Aggregates gravel pit that was being planned in a recently harvested cutblock . We identified several sites that were within the proposed gravel pit boundary, most of which were first identified by spotting artifacts on the ground. It’s not always easy, as vegetation can trick you into thinking you’ve found something, only to realize it was just a leaf.
If you want to try your eye, try to spot the flakes in the above picture!
How many did you find? Give up?
Keep scrolling for the answer…
It can be pretty difficult to spot because of the leaves on the ground but when you really take the time to look you can see five pieces of quartzite debitage.
At our Archaeology Roadshow event in Lac La Biche, in fall 2015 Allan and Juanita Gaudreault brought in several conch shell fossils. These shell fossils were heavily worn and most were down to the central spiral. This made them difficult to identify at first. These are very unusual specimens because these type of marine shells are not found in Alberta. They are native to the Gulf of Mexico. Our initial interpretation (as archaeologists, not palaeontologists) was that this could possibly be a discarded souvenir or a fossil from the Cretaceous period when an ancient seaway stretched from the Arctic to the Gulf of Mexico.
Tree Time Services reached out to Alwynne Beaudoin, Curator of Earth Sciences and Quaternary Environments at the Royal Alberta Museum (RAM), for an answer. The RAM had a conch shell, also found in the Lac La Biche region, donated to the museum in 2011. She has been researching this conch shell and “has not been able to find another record of a conch in prehistoric context from Alberta, though there are records of other marine shells (and) they are unlikely to be Cretaceous.”
Furthermore, the specimen in the Royal Alberta collection was radiocarbon dated to “slightly more than 1000 years before present.” That specimen’s age debunks the discarded tourist souvenir theory. The most likely explanation for the RAM’s shell is prehistoric trade from the Caribbean to Alberta 1000 years ago. There are some artifacts found in Southwestern Manitoba, such as this shell gorget, made from a species of shellfish native to the Gulf of Mexico. However, evidence of prehistoric trade networks between the Canadian Plains and the Gulf of Mexico is extremely rare in Alberta and this would be an artifact of significant information potential.
The potential that the 2015 shells represented trade or travel 1000 years ago, rather than palaeontology from millions of years ago, was pretty exciting. On September 7, 2016 Corey Cookson, Project Archaeologist at Tree Time Services, and Christina Barron-Ortiz, Assistant Curator at the Royal Alberta Museum, made the trip up to the Gaudreault’s home to view the rest of their collection. Upon another viewing of the conch fossils it was clear that our first interpretation was right, and these are remains from the Cretaceous period about 65 million years ago. With permission from the Gaudreaults, a representative sample of the shells were taken by Christina Barron-Ortiz for further study. We will post a future blog once we receive confirmation of the age of the shell fossils. Also stay tuned for another post about some other interesting fossils from the Gaudreault collection.
This week we feature an artifact that was found on a farm near Canora, Saskatchewan. A friend of mine sent the pictures of artifact that her father’s uncle found in a field during the mid-20th century. The artifact is known as a maul which is a large stone with a groove that would be used to haft a handle onto the stone. There were two types of mauls: a heavier one with a short handle and a smaller one with a longer and more limber handle. The heavier one was used as by women for many purposes such as: driving in tent pins, killing disabled animals, breaking up bones for marrow, pounding chokecherries, and pounding dried meat to make pemmican. The smaller one would have been used as a war club by men.
As Canada celebrates 150 years since Confederation it is important to remember that the history of the land we call home goes back thousands of years. Tree Time Services staff discussed some of the most important archaeological sites in Alberta and created a top ten list. Several of these sites can be visited by the general public and a few have public excavation programs that allow volunteers to participate in the digs!
A UNESCO World Heritage site, interpretive centre, and museum located near Fort MacLeod, AB. For thousands of years the Blackfoot and other First Nations guided bison down drive lanes to the jump where they would plunge to their death or be rendered immobile from the fall and weight of the herd. At the base of the cliff these animal carcasses were butchered and distributed between the members of the hunt.
Did you know the name “Head Smashed In” does not refer to the skull crushing demise many of the bison suffered at the site but rather a Blackfoot legend? According to the story a young man wanted to watch the bison fall off the cliff from below but was unfortunately buried by the falling animals. He was later found with his head smashed in (Jack Brink pers comm).
The Writing-On-Stone Provincial Park is located near Milk River, AB, almost on the Montana border. Many rock carvings (petroglyphs) and rock paintings (pictographs) can be found as one wanders through the sandstone valleys and hoodoos. These rock art sites were created by Aboriginal groups visiting the area, telling stories of battles, hunts, and great deeds of individuals. There are also many images of ceremonial nature that depict spirits and the spiritual world.
These images were likely created over thousands of years by the Blackfoot people and other native groups that travelled through the southeastern plains of Alberta. While rock art cannot be directly dated some of the images can be positively dated to after 1700 AD due to the depiction of horses and items introduced by Europeans, like muskets.
3. Quarry of the Ancestors
Located north of Fort McMurray near the community of Fort McKay, the Quarry of the Ancestors is a quarry site and the primary source of Beaver River Silicified Sandstone (BRSS), a highly valued material for making stone tools. The principal use of the site for quarrying BRSS and making stone tools was between 9800-5500 years ago.
Beaver River Sandstone is found throughout the Alberta Oilsands region which was once thought to be sparsely occupied. However, due to the ongoing work occurring in advance of oil sands extraction the region is now considered one of the most densely occupied in Northern Alberta during the thousands of years prior to the arrival of Europeans.
The Majorville Cairn and Medicine Wheel is an ancient Blackfoot ritual centre that shows evidence of use as early as roughly 4500 years ago, and continues to be used today. The site consists of a 9 m wide central cairn (rock pile) which is connected to a surrounding 27 m wide stone circle by 28 spokes. The site is located on a large hill west of the Bow River in southern Alberta near Bassano, AB.
Located in the town of Bodo, on the Saskatchewan boundary half an hour south of Provost, this seven square km site is one of the largest pre-European contact archaeological sites in Canada. The site contains several repeat occupations of the area, with large intact bison pounds and campsites. Tens of thousands of bison bones have been recovered from the site as well as projectile points, scrapers, and pottery sherds.
Unlike many of the other sites on this list, this site encourages visitors to get down and dirty and help uncover Alberta’s past. The Bodo Archaeological Society allows the general public to dig at the site under the supervision of professional archaeologists. The site was also the subject of Tree Time’s own Kurtis Blaikie-Birkigt’s Masters research!
6. Wallys Beach
This ice age kill and butchering site is located in southern Alberta at the St. Mary’s Reservoir near Cardston, AB. The site contains the bones and footprints of extinct animals, including the North American horse and camel, as well as mammoth and caribou. Wally’s Beach was one of the first sites in North America containing evidence of hunting horses.
Originally thought to date to the beginnings of the Clovis era (ca. 13,000 ya), advanced radiocarbon dating techniques now dates the site to approximately 13,300 years ago.
Located approximately 11 miles east of Viking (southeast of Edmonton) are the Viking Ribstones, two large quartzite boulders on top of a high hill. The boulders are carved with a series of grooves interpreted as a representation of a bison vertebrae and rib cage. There are also several circular pits grooved into the boulder which may represent arrow or bullet holes. The pits have also been interpreted as an attempt to recreate the pock-marked surface of the Iron Creek Meteorite, another revered monument.
The bison were extremely important for many First Nations of central and southern Alberta and these rock carvings may have served as a shrine or ceremonial location. Hunters would visit the ribstones to leave offerings of sweetgrass, tobacco, beads, or coins prior to and/or after a successful hunt. There are other ribstone sites in Alberta but all other ribstone sites have been disturbed or removed entirely from their original context.
8. Banff Pithouses
The Banff Pithouses were located along the Bow River and are now lost to the expansion of the Banff Springs golf course in 1928. Documented in 1913 by Harlan Smith, an early archaeologist in the province, the site is one of the first pre-European contact sites to be preserved in Canada. The site contained 14 large (8-10 feet across) circular depressions (1-2 feet deep) with nine of the depressions arranged in an irregular line.
These semi-subterranean houses are common in the British Columbia interior plateau region but are rare in Alberta. The group that built these homes likely crossed the continental divide to hunt bison. For a period of time this was the only site of this type identified in Alberta. Fortunately, several other housepit sites have now been identified in Banff National Park and are currently being researched.
An unusual site for the Southern Plains, the Cluny fortified village is located in the valley of the Bow River on the Siksika First Nation Reserve south of Calgary and is part of the Blackfoot Crossing Historical Park. At the site, dwellings made from logs and earth were surrounded by defensive features including a palisade wall and trenches.
The Cluny Fortified Village site dates to the Late Pre-contact period (Mid 1700s) where the First Nations of the Canadian Plains had not yet had direct contact with explorers of European descent but had access to European goods through trade with other First Nations groups. It is believed that the group that constructed the village migrated to the region from the Dakotas, due to similarities of artifacts with those of the Middle Missouri region. The University of Calgary will be hosting a public archaeology program from May 23rd to June 23rd, 2017 where people can volunteer to excavate at the site. Contact their administrative staff by e-mail at [email protected], or by phone at 1-403-220-8537 for more details.
10. Fincastle Kill Site
Recently named one of the top discoveries of 2015 by Western Digs, the Fincastle site is located in the sand dunes of southern Alberta, near Lethbridge. The 2,500 year old bison kill site contains over 200,000 fragments of bone along with hundreds of stone projectile points representing two cultural groups: the Besant and Sonota.
The most interesting aspect of the site is the discovery of 8 upright arrangements of bison bones placed in sculptural patterns. These are unusual and rare in archaeological sites and the purpose of the upright features remains a mystery. Dr. Shawn Bubel of the University of Lethbridge notes that the bone arrangements are not utilitarian but were intentionally placed in patterns with unique examples of one upright, for example, features a tibia, or lower leg bone, surrounded by four jaw bones, all set on end with the teeth facing outward.
