I have been working in cultural heritage management for three 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.
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.
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.
At our Archaeological Roadshow event in Lac La Biche, AB Allan and Juanita Gaudreault brought in a collection of fossils. The fossils were fragments of a darkly stained bison jaw and a set of blueish grey horse teeth. Mr. Gaudreault told us the specimens were found in a low area near a lake. We came up with two possible interpretations of these specimens: they may have been permineralized due to being in a place with very hard groundwater; or could be dated to the early Holocene.
It is quite rare to find animal remains in the boreal forest in central and northern Alberta. The acidic soils of the boreal forest make for very poor preservation conditions. Animal bone is therefore rare, and these finds could help teach us about past environments in the region.
Tree Time Services reached out to Chris Jass, Curator of Quaternary Palaeontology at the Royal Alberta Museum (RAM), for more information on determining a possible age for the specimens. Jass confirms that “you can get fairly dark staining and mineralization fairly quickly depending on the depositional environment. However, if there’s a horse there, (the Gaudreaults) may be finding some older material.” Horses were native to North America, but went extinct sometime between 13,000 and 11,000 years ago (North American horse teeth were also recently found at the Brazeau Archaeological Survey project ). The horses that are ubiquitous in North America today were introduced by the Spanish in the late 15th and early 16th centuries. Due to the fossilized nature of the specimen and the recovery of the teeth from a possible relic lake bed, these horse teeth may be from the extinct North American horse.
Chris Jass goes on to state that he has “been working with a diver who has been pulling bones out of Cold Lake, and we’ve got Pleistocene dates (>11,700 years ago) on a bison that he’s recovered from the lake. I think there is considerable potential for recovery of late Pleistocene/early Holocene (ca. 11,700 years ago) material in many of the lakes in Alberta.”
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. Christina Barron-Ortiz is a specialist in horse and bison teeth. She confirmed that the horse tooth has the characteristics of several specimens the Royal Alberta Museum recovered from the lake bed near Cold Lake, AB. She also suspected that the bison jaw bone represented ancient bison but could not be as sure as the horse. With permission from the Gaudreaults, the bison jaw and horse tooth were collected and results from carbon dating are expected in the Spring.
At our Archaeology Roadshow in Lac La Biche, AB in fall 2015 a local resident brought in an interesting artifact that was found on a farm near Camrose, AB in the 1940s. The artifact is a 5 and 1/2” round stone with a wide, shallow depression on one side and a smaller lipped depression on the other side. These depressions were formed by grinding or pecking at the stone with a harder stone.
Initial interpretation of the artifact was that it was some sort of bowl or plate. However, there are some problems with this interpretation. First, it would not function well as a bowl due to the shallow depth on the “top” side of the artifact. Second, it also requires a lot of effort to grind these concave features into the stone for something as simple as a serving vessel. Traditionally it was thought that a vessel of this type would not serve much purpose to Native person prior to the arrival of Europeans. Before European contact, people were mobile hunters and it would not make sense to create a plate to be transported from location to location. However, this stereotype has been challenged by recent finds such as carved bison effigies and other robust tools, such as mauls, that were typical of the tool kit of North America’s First Nations.
The “base” of the artifact may be a clue to the age of the artifact. Upon viewing the artifact, Jack Brink, Curator of Archaeology at the Royal Alberta Museum, noted that “the bottom view (of the artifact) shows a ring or foot carved for the bowl to stand on. This is identical to a European bowl or plate. It would serve no purpose to a Native person who would be using a bowl on the ground. Makes me think this, if not made by a European, at least dates to the time after contact (with Europeans).”
The artifact could also be a grinding platform similar to a mortar and pestle or mano and metate popular in Mesoamerican cultures. These artifacts are used to grind down grains and seeds. A similar artifact was found by a farmer near Eaglesham, AB. However, This artifact differs greatly in size and shape from the artifact brought in to our Archaeology Roadshow.
Another interpretation was suggested by Gabriel Yanicki, a PhD student at the University of Alberta. Yanicki, specializing in prehistoric gambling and games, suggests that the artifact may be a Chunkey Stone,typically associated with the Mississippi cultures in the eastern United States. The game of Chunkey involves the rolling of a stone disk while people attempt to hit the stone with spears or sticks. He went on discuss the aspects of the artifact that suggest it may be a Chunkey Stone, “at about 5 ½ inches you’re dead on for size (2-6” most common), and hard granitic or basaltic rocks aren’t unknown.” In terms of style, Yanicki states “the side where the concavity extends almost to the edge is typical of the Cahokia type, while the smaller raised concavity appears in the Salt River and Jersey Bluff types.” However, unlike typical Chunkey Stones this artifact is asymmetrical.
The artifact may also be some sort of ritual or offering platform that may have served a one time purpose. The owner of the artifact is currently talking to Augustana University in an effort to donate the artifact. The “plate” can then be tested for residue analysis to determine if there is evidence of burning or food processing. Megan Caldwell, of Augustana University is also interested in determining the origin of the rock as it appears to be similar to rocks from British Columbia.
In a continuation of our posts in honour of “Mysteries of China” playing at the Telus World of Science for the months of February and March, I decided to look back on my trip to the Terracotta Warrior museum just outside of Xi’an.
We visited the Terracotta Army Museum in the winter of 2014. This was a good time to visit because the crowds were minimal but it was bone-chillingly cold. The Terracotta Army is indoors but there are several large windows and the door is kept open so it is still pretty cold in there too. So bundle up!
We took a local bus that you can catch just east of the railway station located north of the city wall approximately 3.5 km north of the Bell Tower. There will be several buses that will take tourists directly to the museum. The ride takes about 45 minutes and will take you to a large parking lot.
There are number of signs that have been translated into English but if you have limited knowledge going into the site it might be a good idea to get a guidebook or hire a guide.
The terracotta sculptures were created to represent the armies of Qin Shi Huang and their purpose was to protect the emperor in his afterlife when he died in 210-209 BCE. The Terracotta army is located east of the large mausoleum for the emperor that is underneath a 76 m tall pyramid-like mound. Work on the mausoleum began in 246 BCE (when Emperor Qin was 13 years old) and required 700,000 workers. This tomb has not been subjected to archaeological excavation as of 2017.
From the parking lot, you will see a large statue of Emperor Qin Shi Huang, walk toward it and continue walking west (about 15 minutes) until you come Pit 1. When you first walk in to Pit 1 you will be blown away by the number of statues (over 6,000!). In this pit you can see the 11 corridors of warriors placed on pottery bricks separated by rammed earth walls. The corridors had wood roofs that were covered with reed and clay then covered with 2 to 3 m of soil.
As you walk around the side of the vault you can get a little closer to some of the recently restored statues. You can also see a sign pointing to the location of well dug by a farmer that discovered the site back in 1974. The farmer was at the museum when I visited and he signed a nice book of photographs that I purchased.
You can exit out of the back of Pit 1 and continue to Pit 3 which is a much smaller vault with one chariot and several high-ranking officers.
Exit to the east and continue to Pit 2. In pit 2 the soldiers have not been restored as in the other pits.
Once you are done with the main excavation pits you can go two exhibits on either side of the main courtyard. These are the Exhibition of Ancient Weapons to the north and the Bronze Chariot Exhibition Room to the south. In these rooms you can get a little closer to the artifacts (but they are behind glass of course) to see the little details. You can see some pieces that still have the paint intact.
I was also unaware of all the non-military types of statues that existed. There are more than just warriors and archers that have been found. The emperor also wanted his entertainment and servants in the afterlife. There are Terracotta statues of musicians, acrobats, and women as well.
You can also see the Bronze Chariot at this exhibit.
They also have a really good exhibit that educates the public about the archaeological processes of excavating, conserving, and restoring the Terracotta statues.
After we were done exploring the museum and pits we headed back to our hostel (Xian Shuyuan International Youth Hostel) where we had some hot showers and then we headed down to the Terracotta Warrior themed bar in the basement and drank some China beers.
