Ecological Catastrophes in Alberta’s Past: The Mazama Volcanic Eruption

August 7, 2014April 11, 2017toddkristensen

Did you know that one of the largest ecological catastrophes in Alberta’s human history was a volcanic ash fall? Around 7600 years ago the skies were blackened for many days and the prairies of Alberta were blanketed with roughly 15 cm of ash ejected during the Mazama eruption.

To create awareness of this event and other important moments in Alberta’s past, a team from the Historic Resources Management Branch, the University of Alberta, and the Royal Alberta Museum initiated a project called the Heritage Art Series. The goal is to captivate public audiences with artwork that creatively explores ancient landscapes, relationships between people and their surroundings, and the enduring physical record of human activities. We hope the series inspires a desire to learn more about our province’s heritage and that a greater awareness of the past will instill a deeper respect for it. We’ll release the first four paintings in the series over the coming weeks with explanations about the significant events and figures that each scene depicts.

The first painting (above) by Karen Bishop captures a surreal landscape of Southern Alberta as it would have looked 7600 years ago during the Mazama volcanic eruption. While the volcano that erupted was in Oregon (at modern day Crater Lake), it only took about 12 hours for some of the estimated 100 km³ of ash to reach Alberta. The ash smothered plants, contaminated fresh water, and would have filled animals’ lungs. Airborne particles would have caused intense lightning storms. Huge swaths of dead vegetation combined with frequent lightning led to widespread fires.

Ash depth comparison — This figure depicts how deeply Edmonton and Calgary would be buried if all of the ash from the Mazama eruption were confined to the city limits.

By studying micro-organisms and microscopic silica particles in soils and lake beds, scientists, including a team of ‘tephrochronologists’ led by Dr. Duane Froese from the University of Alberta, are learning more about the ecological impact and timing of volcanic eruptions in Western Canada. Climatic systems were altered by the relatively dense ash ejected into the atmosphere, the pH of soils and water bodies changed, and mobile animals like bison likely abandoned their territories for lack of fodder and/or drinking water. However, while the impact was widespread, preserved pollen suggests that plant communities rebounded rapidly. Overall, landscapes may have recovered fairly quickly from volcanic eruptions (on the scale of 2-10 years), but the effect on human populations was likely more pronounced.

The archaeological record reveals that portions of the province were abandoned for several decades and possibly much longer. Notable changes in weapons and raw materials that were used for stone tools around the time of the Mazama eruption may be linked to this ecological catastrophe; the people that returned to once-vacated landscapes were either different from their predecessors or they arrived with new ideas acquired from their neighbours. This, and other large-scale eruptions in North America over the past 10 000 years, changed the direction of local human histories. New cultures, technologies, and social networks emerged after volcanic events.

Despite the dramatic nature of volcanic eruptions, few people realize that Alberta has experienced them in the past and that other ecological catastrophes have influenced the development of Alberta’s past cultures. Palaeoenvironmental scientists and archaeologists have learned a great deal about past ecological events that, while educational, have more profound implications for the way we manage ecosystems and respond to the world around us. By studying the past, we can learn how to brace for the future.

To learn more about the Mazama eruption and other palaeoenvironmental studies in Alberta, visit some of Dr. Alwynne Beaudoin’s research at the Royal Alberta Museum.

Stay tuned for the next installation of the Heritage Art Series, which will discuss the archaeological and historical records of First Nations fishing in Northern Alberta.

A Treasure Trove of Albertan Archaeology Now Online!

June 24, 2014August 7, 2014Matthew Francis

Back in the 1970s and 80s, the Archaeological Survey of Alberta published a highly-regarded series of occasional papers, known affectionately in archaeological circles as the “Blue Series,” for its characteristic cover colour.

Occasional Paper No. 1, published in 1976.

Robin Woywitka, Cultural Land Use Analyst with the Historic Resources Management Branch commented on how this rich collection of literature has become a coveted resource, with well-worn copies sought after by professional archaeologists and others interested in the field.

Woywitka observed, “The two series were established in the 1970s and 1980s to help disseminate the results of archaeological work conducted in the Province. Thirty five Occasional Paper volumes and 17 Manuscript Series volumes were issued from 1976-1994. These volumes cover the entire breadth of human history in Alberta, from the late glacial to the recent past, and from the Great Plains to the Rocky Mountains into the Parkland and Boreal Forest.”

It’s now online!

As it turns out, the series is not just a relic of the past, but has stood the test of time. Now, by popular demand, the whole series is available online free for download! Jared Majeski, Heritage Division Web Assistant, collaborated with Woywitka to see the project through to completion. Many avid archaeologists have requested this, and those requests have been heard.

Robin Woywitka, Cultural Land Use Analyst, and Jared Majeski, Heritage Division Web Assistant, proudly display a hard copy of one of the Occasional Paper series. — Robin Woywitka, Cultural Land Use Analyst, and Jared Majeski, Heritage Division Web Assistant, proudly display a copy of one of the Occasional Paper series, now online.

In addition, the series is being revived! New contributions to the Occasional Paper series are welcome. The new series will focus on the annual review style volumes that were a hallmark of the original Occasional Papers. Please consider submitting a manuscript on topics of Alberta archaeology (submission guidelines are here). The deadline for submissions for the 2014 annual review volume is January 31, 2015. Ideas for edited thematic volumes that stretch beyond the confines of Alberta are also welcome.

Okotoks Big Rock – Managing Vandalism with Technology

June 17, 2014June 17, 2014rebeccagoodenough

The word ‘Okotoks’ translates from the Blackfoot language as ‘Big Rock.’ The name was given by the resident indigenous people to a very large boulder that is known as a glacial erratic – boulders that have been moved from their original location by glacial ice. Okotoks is by far the largest erratic in Alberta; it is about the size of a two-story house and is estimated to weigh nearly seven million kilograms. The Big Rock is a well-known landmark in southern Alberta. It is a designated provincial historic resource owned by the Government of Alberta, and is accessible to the public by means of a hiking trail, signage and a parking lot. What is not well-known is that the Okotoks Big Rock has a great deal of Aboriginal rock art painted on its surfaces.

Rock art includes pictographs (paintings) made with a red paint composed of iron-rich hematite (red ochre). The existence of a few red ochre images on the Big Rock has been known for decades, but the revolution in digital photography and image enhancement has brought to light a whole lot more art on the Okotoks erratic than previously known. Specifically, we now know that some areas of the rocks were extensively rubbed with red ochre. Since these red areas lack definable rock art figures like humans and animals, it was long believed that the red blotches were simply part of the rocks’ natural colour. Through enhancement we can now pick out hand prints and finger swipes, telling us these red blotches were indeed made by human beings.

All rock art sites are sacred to Native people; rock art represents communication between human beings and the spirit world. Blackfoot people still visit the Okotoks site, conduct ceremonies, and hold the site in great reverence. Thus, it is all the more sad and frustrating that the Okotoks erratic has been subjected to extensive and increasingly frequent bouts of vandalism. As the site is operated by the province and is open to the public, there comes a point where some action needs to be taken. It is an eyesore, an embarrassment and severely disrespectful to the Blackfoot beliefs about the sacred character of the rock. But what can be done with a massive rock surface covered with graffiti that underneath lies fragile, precious painted pictures that tell stories of ancient Aboriginal people?

In the past few years, serious incidences of graffiti were washed off the rock face using a high pressure water sprayer. More recently, an environmentally friendly paint stripper had been used with good success. But critical to any graffiti removal has been potential impact to underlying rock art. We realized that we could never properly manage the site until we had a high-quality “map” of the rocks that plots the complex rock structure and the locations of all the rock art images. We realized that the best way to make a physical record of the Big Rock was to record it in 3D using a portable laser scanner. While documentation won’t stop vandalism at Okotoks, it will make us much better prepared to deal with future instances in a way that protects significant historical resources.

A partnership with the internationally respected organization CyArk was formed. CyArk is a nonprofit organization dedicated to digital recording and preservation of the world’s most significant sites. Among their credits are 3D recordings of the statues of Easter Island, Pompeii, ancient Thebes, and Mt. Rushmore. CyArk also digitally stores the 3D information for each site, serving as a world archive of heritage data. CyArk retained a local service provider to assist with the equipment and expertise to conduct the laser scanning. In early October 2013 the entire external surface of the Okotoks Big Rock, including the tops of the rocks and some internal crevices, was scanned during two days of field work. The result is a strikingly accurate rendering of the Okotoks erratic in both its geometric shape and the plotting of all known rock art images. The project also resulted in production of an accurate 1:200 scale model of the Rock that will be useful for planning and educational purposes.

In addition to the rendering and scale model, the project also raised awareness about negative impacts associated with graffiti and heightening understanding of the value and importance of historic resources to the community. Further Alberta Culture now has a sophisticated tool to use for site management.

Sadly, the rocks have already been subjected to more graffiti in the months since our project ended; however, we now have accurate information on the type and location of rock art that will assist in graffiti removal efforts. There are other threats to the cultural and natural significance of the Okotoks erratic. It has long been a favoured place for climbers, subdivisions are rapidly encroaching on the site, and public visitation is increasing. There are many challenges ahead in the long-term management of the Big Rock, but thanks to the careful recording conducted through Innovation Program funding we have a solid baseline of information about this very special place that will guide future management.

Plane Wrecks, Aviation Archaeology and Northern Heritage

May 20, 2014May 20, 2014editor, RETROactive

This post continues our look at the work of Alberta’s Archaeological Survey. An expanded version of this article can be found in the Fall 2013 issue of the Canadian Aviation Historical Society Journal.

Plane wrecks are unique and dramatic physical records of human movement. We document here the archaeology and history of a 1952 B-17 plane crash to help illustrate the deep and fascinating roots of northern aviation. We reconstructed mission details from accident reports and discovered interesting connections to the famous Northwest Staging Route, which was a significant transportation network that spanned Alberta.

Scale of the SB-17G and the 8 crew members on the ill-fated 1952 flight (diagram T. Kristensen).

On July 11, 1952, a modified B-17 (an SB-17G) set out from Alaska on a search mission in the Yukon to locate a crashed Royal Canadian Air Force plane that had disappeared in June. The B-17 was originally a Second World War era high altitude bomber, legendary for the damage it could endure in combat. Its durability, combined with the availability of surplus aircraft after the war, meant that B-17s were used for many post-war activities including weather survey, forest firefighting, and search and rescue.

Eight crew members of the United States Air Force 10^th Air Rescue Squadron were aboard the SB-17G as it entered a small mountain valley. The navigator was unfamiliar with local topography and 15 seconds into the valley, the crew began adjusting power in an attempt to avoid a fast approaching valley wall. Because of its original purpose in high altitude flight, the SB-17G was not particularly maneuverable and couldn’t recover from its predicament. Stalling within meters of the ground, the left wing struck an alpine slope sending the aircraft into an arching skid path that tore through birch trees and bedrock cobbles for several hundred meters before coming to rest. The wreck was quickly consumed by flames. Five men evacuated immediately but the remaining three caught fire in their frantic attempts to depart. An heroic lieutenant escaped the wreck and pulled one man to safety while another emerged from the wreck engulfed in flames. Although he was immediately doused, the airman couldn’t recover from severe burns and died six hours later. The crew spent a somber night in the cold mountains before being rescued the next day.

The story of the SB-17G crash represents a small but significant piece of aviation history. Northern aviation assumed an international importance with the growth of the Northwest Staging Route in the 1930s. The Canadian portion began in Edmonton and linked a series of northern airstrips up to Alaska and Russia. Like Edmonton, most towns along the route were initially First Nations gathering spots that developed into fur trade posts when traders arrived. They eventually grew into agricultural, mining, forestry, or oil and gas centres. The Alaska Highway was built to connect these centres to help protect North America from a potential Pacific attack. After the war, the Northwest Staging Route remained important for military exercises (which drew the SB-17G to the Yukon) and as a transportation route to other international conflicts.

Given their experience on the land, First Nations people were hired as guides to help survey the Alaska Highway before construction. Consequently, much of the highway followed First Nations trails that existed for millennia. Other portions followed Gold Rush trails that started to criss-cross the north in the late 1800s. This synopsis illustrates how modern transportation systems in the north have deep histories. The interconnected travel network that now links northern towns has witnessed birchbark canoe paddlers, moccasins, Gold Rush wagons, tank treads, and jet streams.

Territorial and provincial heritage legislation exists to preserve the remains of historic events like the SB-17G plane crash. A research permit is required to excavate any historic resource be it a 2 million year old fossil, a 2000 year old fishing camp, or a Second World War era aircraft. Historic objects are not permitted to leave the territories or provinces unless authorized by respective governments, which means artifacts can’t be re-located without permission. This legislation has created some conflicts in the past between heritage managers and people interested in salvaging plane wrecks but positive relationships and advance communication can help ensure that aviation historians and archaeologists work together to share their passion for the past. The story of the SB-17G crash highlights the military importance of the north and the historical depth of human movement.

On the Deep Roots of Beaver and Human Relationships in Alberta

February 13, 2014May 7, 2014editor, RETROactive

This post continues our look at the work of Alberta’s Archaeological Survey. Previously, we explored “10, 000 years of hunting in Alberta”, as shown in the archaeological record and how the horse changed the west. Today we look at that Canadian icon: the Beaver.

There are few animals in the north whose history is so intricately interwoven with people than the beaver. From the early fur trade to modern environmentalism, the beaver has chewed its way into numerous facets of life in Alberta. Paleontology, archaeology, history, and modern politics combine to tell an amazing story of human-beaver relationships in the province.

The earliest beavers lumbered into the province over five million years ago. By two million years ago, the modern beaver (Castor canadensis) was living alongside a colossal cousin that was five to six times larger (Figure 1). The giant beaver (C. ohioensis) weighed up to 160 kilogram and was just under 3 metres long. It went extinct around 10 000 years ago. First Nations’ stories tell of the beaver’s role in creating the world by molding the primordial mud into an island fit for humans. To Alberta’s first people, beavers also furnished important materials for tools, clothing, and food. Archaeology sites across the province have yielded beaver bones where very few other animal remains were found. This indicates that beavers were crucial to human diet, particularly during winter. Beavers were captured with willow bark nets, stone-tipped spears, and sinew snares set along beaver trails and canals.

Figure 1: Beaver scale comparison (by Todd Kristensen).

Three major anatomical traits made the beaver important to various cultures in Alberta through history. Beavers stay warm with large fat deposits and very dense, barbed hair. The former trait explained why beavers were important winter foods while the latter trait fueled the fur trade that shaped our nation. The third important trait is durable teeth that enable beaver’s incessant chewing. When it came time to design wood working tools, prehistoric people enlisted the beaver’s dental assistance. Ancient engravers and chisels were made of beaver teeth lashed to a wooden handle. Beaver tooth engravers were common in the toolbox of early northern people and provide a unique glimpse in to the ingenuity of First Nations.

Figure 4: Beaver hat fashions during the fur trade (by Terry Pamplin and Todd Kristensen).

The strong, oily, and barbed under-hairs of beaver were ideal for making superb quality felt hats that were popular from the late 1500s-1800s (Figure 4). Prior to European contact there were likely over 10 million beaver in Canada. These vast numbers were an economic ‘boon’ for Europeans, but the abundance was short-lived. Beaver populations were reduced by as much as 95% in two centuries. As each new fur trade post was established on Alberta’s lakes and rivers, a zone of beaver depletion rapidly radiated outwards until local numbers dwindled and the traders moved on. Fur trade competition decreased in the 1820s and areas of the Canadian northwest were managed more judiciously so that beaver populations recovered and future crashes were prevented. Despite lower populations, hundreds of thousands of beaver pelts and over 10 tons of castoreum (a highly fragrant secretion produced in beaver castor sacs) were shipped out of the Athabasca and Saskatchewan River Districts in the early 1800s.

Biologists like Dr. Glynnis Hood of the University of Alberta, are researching the ecological impact of the fur trade and modern beaver dams. They’ve found that beavers drastically alter local water levels as well as wetland biodiversity, fire regimes, floods, carbon sequestering, and the filtering of local toxins. Dr. Hood’s research explores how knowledge of the beavers’ aquatic engineering can inform land management decisions. The esteemed human-like propensity for industrious labour earned the beaver the honour of our national animal and it may become a tool to mitigate future climatic oscillations (e.g., droughts and floods). Beaver teeth, winter fat, and dense fur represent biological adaptations that early Albertans exploited to suit their needs; dam building may be the latest trait that Albertans utilize in their ever evolving relationship with beavers.

Hooves in History: How the Horse Changed the West

December 4, 2013May 7, 2014Matthew Francis

This post continues our look at the work of Alberta’s Archaeological Survey. Previously, we explored “10, 000 years of hunting in Alberta“, as shown in the archaeological record. While RETROactive will continue to be your source for news and information about Alberta’s historic places, we are branching out to provide insights into other aspects of our work to understand, protect and conserve historic resources.

The chronological spread of the domestic horse into Alberta over the last 500 years.

When horses galloped across what would become the US border onto Alberta’s rolling prairies in the 1720s, it was a bit of an overdue homecoming. It had been roughly 10,000 years since the province’s expansive grasslands shuddered under hard equestrian hooves. Fossils indicate that North America is the original home of the horse where it first appeared millions of years ago.

Ancient spear from Alberta that was coated in blood of the now-extinct Mexican horse.

The now-extinct Mexican horse (Equus conversidens) ventured well north into Alberta’s tundra meadows and onto the menu of Alberta’s first humans. Ancient residues of horse blood were found on stone spear tips used over 10,000 years ago in southern Alberta. Fossil horse bones have also been found near Grande Prairie, Taber, Cochrane, and in the Edmonton area. Around 10 millennia ago, the horse mysteriously disappeared. When the horse returned with the Spanish 500 years ago it assumed a central role among Indigenous and European cultures in the West. The story of the horse in Alberta is a fascinating ride through the province’s heritage.

Once groups like the Blackfoot and Assiniboine mastered horseback riding, the horse occupied just about every dimension of life on the Plains. The new hooved pets created new hunting strategies, they changed the way people moved across the prairies, and they altered the dynamics of Plains warfare but reconstructing when and how the domestic horse spread into Alberta has been tricky. Historic records offer only a handful of references to horse adoption by Indigenous people but a unique piece of heritage offers fleeting and beautiful glimpses of how the horse changed the West. Writing-on-Stone Provincial Park in southern Alberta houses one of the largest collections of rock art in North America. For over a thousand years Indigenous people carved and painted their stories on the sandstone hoodoos and canyon walls and the horse looms large in those depictions.

This carving (‘petroglyph’) from Writing-on-Stone depicts a domestic horse in a buffalo hunt.

Horse carvings depict a wide variety of events and beliefs including battle scenes, hunting expeditions, and tallies of horses acquired through trading or raiding. In everyday life, some horses replaced the dog as beasts of burden while other horses were highly revered as ‘buffalo runners’, prized for being long-winded and intelligent while overcoming an 800 pound buffalo. For buffalo hunters who needed both hands free for their weapons, a well trained horse was a matter of survival.

A painting by George Catlin from the 1800s of life on the Canadian Plains (reproduced with permission from the Bruce Peel Special Collections Library, University of Alberta).

The horse also quickly galloped into peoples’ social lives. Families that acquired many horses gained prestige and respect. Horse raiding became a mark of courage for many groups and horses were traded for a multitude of things including European goods, food, membership into societies, and spiritual power. During the fur trade while slick beaver furs were motivating European economic interests in northern Alberta, horses, guns, and buffalo meat were becoming entwined in complex trade networks that would shape the history of the prairies. When the buffalo eventually vanished, the hooves of the horse pounded on.

This combat scene from Writing-on-Stone shows an early horse draped with body armour (photograph reproduced with permission from Michal Klassen).

The unique collection of rock art at Writing-on-Stone is a provincial treasure that captures pivotal centuries of modern Plains cultures. For this reason, the area is both a Provincial Historic Resource and a National Historic Site. Writing-on-Stone is still a sacred place to the Blackfoot people; a place where spirits dwell among the sculpted bedrock. Visitors are encouraged to learn the story of this powerful place. One of the many benefits of the stony archive of art on the Milk River is that it can be enjoyed and appreciated under blue skies.

What better way to learn how the horse changed the west than from reading the walls of Writing-on-Stone while cool breezes blow in hints of sage and a red-tailed hawk reads over your shoulder? Site protection combined with a healthy respect for Blackfoot traditions and the archaeological record will ensure that the history of the old West will endure and the story of the horse will ride on.

Big Game in Deep Time: 10,000 years of Hunting in Alberta

November 27, 2013May 7, 2014Matthew Francis

RETROactive has been publishing for almost three years now. We will continue to be your source for news and information about Alberta’s historic places.

At the same time, we’re going to start bringing you articles providing insight into other aspects of Alberta Culture’s work to understand, protect and conserve historic resources. This post is the first showcasing the work of Alberta’s Archaeological Survey.

By the time Europeans and their guns arrived, 250 years ago, in the place that would become Alberta, the area had already witnessed 10,000 years of big game hunting. Alberta’s prehistoric hunters killed mammoth, an extinct horse, an over-sized species of extinct bison, and even camels that roamed the plains millennia ago (Figure 1). Analyses of stone tools have revealed traces of mammoth and horse blood on spear tips in northeast Alberta and southwest of Lethbridge, respectively. Other evidence of prehistoric big game hunting includes human-made cut marks on animal bones found with stone tools.

Figure 1: A selection of wildlife that greeted Alberta’s hunters 10,000 years ago.

At eight tons and over three meters tall, the woolly mammoth towered over human hunters. So how did people with thrusting spears bag this massive grazer without being gored? Most likely with ingenuity and teamwork. Mammoths, as well as horses and large bison are herd animals that were probably corralled into situations that gave people the upper hand like bogs, canyons, and cliffs where lumbering prey would get trapped or stuck in the mud. In addition to the dangers of hunting big animals, people also had to contend with big predators like the now-extinct American lion, which has been found in Calgary and Edmonton. It was taller than a polar bear (but much faster) and likely kept people on fearful watch.

By 8,000 years ago, Alberta hunters acquired a new weapon that put some distance between themselves and future food: the atlatl (spear thrower) and dart (a short spear). The atlatl enabled people to throw weapons with much greater force (Figure 2).

Figure 2: Hunting technologies in Alberta.

Around 2,500 years ago, stone tips on ancient weapons become much smaller which indicates the arrival of bow and arrow technology. The bow and arrow was effective at about 30 m away (Figure 3) so why adopt a new hunting system that required people to get closer to big game than the older atlatl?

Figure 3: Hunting ranges of Alberta’s ancient weapon systems.

Imagine wearing a blind-fold on an autumn day and listening to the difference between a stationary archer and a javelin thrower lunging across the dry leaf litter. The bow and arrow was quieter because it required much less movement and it was also more accurate.

Several other hunting technologies existed in addition to spears, darts, and arrows. Bison and pronghorn antelope were stampeded over cliffs and canyons (Figure 4);

Figure 4: Ancient pronghorn hunting trap. The map is of stone drive lanes in Southeast Alberta and the photograph at right is of archaeologists mapping a pronghorn drive lane north of the Red Deer River.

Head-Smashed-In Buffalo Jump near Fort Macleod is a world famous example that was used for over 5,000 years. Small piles of stone were built in converging lines creating drive lanes that extended several kilometres. These piles stabilized branches and leather strips that waved in the wind and frightened bison, which were funnelled down the drive lanes and over steep cliffs. Up to 200 animals could be killed in one day. Buffalo jumps are one of the largest prehistoric meat-capturing events on the planet and it happened thousands of times over thousands of years on the rolling prairies of Alberta.

Moose, elk, deer, and caribou were snared, stalked in deep snow, and speared from boats while swimming. In the winter, beaver and bears were speared in dens and lodges. Alberta’s early hunters called game with birchbark horns, rubbed scapulas on trees to imitate antler raking, dressed in coyote skins to more easily approach bison, and regularly burned small areas to stimulate plant growth that attracted big game. Archaeology tells a story of thousands of years of successful big game hunting strategies. While archaeologists have learned a great deal about ancient hunting, much remains to be discovered.

Alberta Culture’s Archaeological Survey maintains records of new archaeological discoveries across the province to enable their protection. If you come across an arrow head or other stone tools, please take a few photographs or jot down some notes to share with us so we can continue to learn about the province’s rich hunting history. You can contact the Archaeological Survey at 780-431-2300.
