Advancing Archaeology: the Occasional Paper Series in 2019

Written by: Krista M. Gilliland, Western Heritage and Todd Kristensen, Archaeological Survey of Alberta

The Archaeological Survey of Alberta is proud to kick-off Occasional Paper Series No. 39 with its first two articles available for free. As with the previous volume, individual articles in the Occasional Paper Series are published online throughout the year, with the final, compiled volume released at the end of the year. We encourage submissions from archaeologists in cultural resource management (CRM), universities, and other heritage professions.

Submissions to Occasional Paper No. 39, edited by Krista M. Gilliland, are welcome.

Occasional Paper Series No. 39, “Advancing archaeology: Industry and practice in Alberta, 2019,” is dedicated to an influential member of the archaeological community in Western Canada, Terry Gibson, who passed away in 2018. The first article in the volume is a tribute to him.

Terry Gibson (1954-2018) played an important role shaping the CRM community in Western Canada.

The second paper is a summary of archaeological features called bone uprights that appear in Alberta and across the Northern Plains. These features consist of animal bone (usually bison) that was vertically embedded in the ground. Archaeologists have come up with several ideas to explain these curious components of pre-contact sites.

The title of the current volume – “Advancing archaeology: Industry and practice in Alberta, 2019,” refers to Terry Gibson’s legacy in the province and an important goal of the Occasional Paper Series. We hope the series provides a venue to CRM archaeologists, heritage managers and others to improve the discipline in Alberta. Interested authors can pitch a paper or idea to the editorial committee.

Knife River Flint quarries and the Alberta connection

Written by: Emily Moffat, Regulatory Approvals Coordinator, Archaeological Survey of Alberta

Stone tools were central to life in pre-contact North America and the rocks that they were made of were highly valued. The archaeological record throughout vast regions of North America, including much of Alberta, contains Knife River Flint (KRF), one of the most significant and intriguing tool stones used before the arrival of Europeans. KRF gets its name from the Knife River, a tributary of the Missouri River that flows through the United States Midwest and Southeast Regions.

In an era of limited human mobility compared to modern times, KRF was regularly transported hundreds of kilometres from its source in North Dakota, where it was quarried for thousands of years. A relatively small geographical region contains the majority of quarry pits and this location is the hub of KRF’s widespread distribution.

Pebble Chert Quarries in East Central Alberta

Stone tools and debitage, also known as lithics, are one of the most common types of artifacts found in Alberta. In the past, stone tools were an essential part of Indigenous ways of life. These stone tools and associated debitage (pieces flaked off while the stone tool was being manufactured) are made from a variety of stone types, but generally they need to be produced from quality raw materials. The characteristics of a quality raw material for making stone tools include stones that are finer-grained, somewhat brittle and uniform in texture and structure, and have few or no inclusions because these might make the rock break in unpredictable ways. Some of the highest quality material that was used in Alberta in the past comes from other places around North America, such as Knife River Flint from North Dakota, obsidian from British Columbia and the northwestern United States, and other types of cherts, argillites and other materials from neighboring provinces and states. However, several material types are available locally. Some of the most common types available in Alberta include quartzites, siltstones, cherts and petrified wood. In East Central Alberta, a common type of rock utilized by Indigenous groups in the past was pebble chert. There are areas where this stone is readily available and it can be high enough quality to be knapped into tools. While these pebble cherts can sometimes be found today in road cuts or blowouts all across East Central Alberta, there are two pre-contact quarries and associated archaeological sites near Consort, AB where large concentrations of these materials were found, collected and utilized. At these sites, there is evidence that Indigenous groups used rounded and fist-sized pebbles of chert to make stone tools.

The Misty Hills quarry site and complex (Borden block EkOp) is unique because it has large densities of both high quality chert and quartzite pebbles found in more than 130 blowouts across the site. In addition to the raw pebbles, there are many associated quarry Read more

Computer modelling and forgotten river crossings

Often, archaeological discoveries are thought to only result from physical archaeological surveys. However, later data analysis and computer modeling can also provide important insights not easily seen in the field. Recent efforts to reconstruct possible past travel routes along the Red Deer River north of Brooks help illustrate just such a situation. Exciting archaeological finds were made, both through traditional archaeological survey techniques in the field, as well as with modern computer modelling approaches later in the office. These finds highlight the importance of viewing the past not simply as a series of isolated archaeological sites, but rather as a continuous cultural landscape.

Two seasons of fieldwork, consisting of more than 400 km of pedestrian survey, were conducted along the edges of the Red Deer River valley for some 43.5 km of the river’s course. The area was situated in some of the warmest and driest parts of the province, with vegetation consisting primarily of grasses, a few shrubs and vast swaths of prickly pear cactus. While some portions were virtually devoid of vegetation, unusually high amounts of precipitation throughout the region had encouraged thick grass growth in most other areas, and had kept the prairie a rich green colour for much longer than usual.  Hidden within that thick cover of grass were large numbers of archaeological cobble features – the location of close to 1,000 of which were recorded with GPS. Unsurprisingly, the vast majority of features recorded during the fieldwork were standard cobble rings that marked the locations of past tipis. Also recorded, however, were significant numbers of other types of cobble structures, like standard cobble cairns and cobble arcs, as well as more unusual features , like tailed cobble rings, hollow cairns, and medicine wheels.

Newly Discovered Medicine Wheel Detail Plan
Southern Alberta is home to a greater number of medicine wheels than any other jurisdiction, and the Red Deer River appears to be a particularly rich location for them. Image provided by Terry Beaulieu.

A total of five known medicine wheels were located in the area. Due to land access issues, however, only two of the five were visited during the present investigation. One new medicine wheel, though, was discovered. Like the other five medicine wheels in the vicinity, the newly discovered medicine wheel lies quite close to the valley edge, overlooking the Red Deer River to the east. It has a very well defined 5.25 m diameter central cobble ring from which four less-well defined linear cobble spokes radiate. The three longest spokes each terminate at a cobble cairn. A cobble ring is bisected along its northern edge approximately midway along the east northeast running spoke and a tailed cobble ring, along with a standard cobble ring, lie close by.

The wealth of locational data collected for the recorded cobble features was critical to computer analyses later conducted in the office.  Close to 1,000 data points – the locations of archaeological cobble features – were imported into a geographic information system (GIS) to form the basis of a sophisticated spatial modeling analysis. Archaeological applications of GIS have often been criticized for placing too much emphasis on the physical environment and of therefore being guilty of excessive environmental determinism. The modelling approach taken in this study was designed to intentionally emphasize cultural elements in order to address such concerns with what is generally considered to be a landscape archaeological approach.

One of the ways cultural elements were emphasized was through identifying and integrating the concept of place into the GIS analysis. Incorporating locations into the GIS that had been identified based on place names known to have been used by Indigenous people was one such method employed. Past places were also determined by using the archaeological information collected in the field. Locations indicative of important places, for example, were identified by locating significant concentrations of standard cobble rings, or finding the presence of known ceremonial features such as medicine wheels and hollow cairns, among others. GIS modelling was then conducted in an effort to locate and model pedestrian travel routes that may have been employed by past people during their summer travels through the region when heading to the nearby important location of Hunting Hill.

Travelling routes along Red Deer River

The GIS models indicated a crossing point  located near where Bull Pound Creek empties into the Red Deer River. The problem, however, was that most early maps of the area indicated the closest known river crossing was upstream from there at Lord Lorne Crossing. It therefore appeared the GIS models were flawed. Further investigation, however, revealed that was likely not the case.

In the summer of 1859, Captain John Palliser travelled through the region as part of his multi-year expedition through western Canada. He was one of the first Europeans to visit the region and the maps he produced are some of the earliest created of the area. During those travels he wrote of visiting “Blackfoot Indian” camps. The route he travelled during one of those visits ran down the east side of Bull Pound Creek and crossed the Red Deer River at the point where the creek emptied into the river – at almost the exact location indicated by the GIS models. Given that Palliser was likely being guided by residents of the camp, who would have been familiar with the best routes and river crossings, the concurrence between Palliser’s map and the GIS models indicates the modelling process was indeed successful in identifying the location of a river crossing point used by past peoples.

It is interesting to note that less than a quarter century later, when George M. Dawson, of the Geological Survey of Canada, created his maps of the area, the crossing near the mouth of Bullpound Creek was no longer recognized by those creating the maps. Lord Lorne Crossing, significantly upstream from the mouth of Bullpound Creek, had instead replaced it as the important crossing place. Such a shift illustrates how quickly changes occurred on the prairies in the mid to late 1800s, and how fast Indigenous information became lost and undervalued during European map making. Information about the locations of significant places to past people does not have to remain lost and forgotten, though, and can be resurrected through thorough investigation and careful research, as is evident by the discovery of a previously unknown medicine wheel and the identification of a forgotten river crossing. Both are significant additions to the archaeological record that, in addition to helping inform our understanding of the past, also show that important new archaeological discoveries are still being made, whether through old fashioned archaeological legwork or modern computer analysis.

Beading the Way: Adornment and the Quest for Cultural Survival

Adornment reflects a symbolic visual language that includes materials and designs that contain communally understood messages. That is, the clothing or items we wear convey information about us to other people. The expression of these messages through clothing, tattoos, jewelry, or body paint, conveys information about an individual, group, society, or religion. Beading, and other embroidery techniques, can be seen as one aspect of adornment for Indigenous groups, and one that played a central role in cultural preservation for many groups post-European contact.

Beads have been found in the archaeological record as early as 40,000 years ago, and are staples in decorative adornment. Beads can be fashioned from many different natural materials including plant seeds, stone, gems, shell, bone, or metal. While plant-based seeds are the easiest to manufacture due to their availability, beads made from bone, metal, gems, or semi-precious stone require more effort and technology to produce, and are therefore more highly valued.

Prior to European contact, Woodland and Plains cultures of North America decorated the skins of animals, tree bark, and their own bodies with locally available and traded materials. Materials such as seeds, berries, porcupine quills, moose hair, Read more

‘Pollen’ me back into history!: What Pollen can tell us about Archaeological Sites

Anyone with allergies knows when spring begins, and plants start pollinating, the offensive ‘dust’ can wreak havoc. However, one of the great things with pollen, from an archaeological perspective, is the fact that it gets dispersed annually. This means that each year, the ‘signature’ of the pollen released tells us about the landscape at the time. Plants have evolved to reproduce with pollen in several ways, and one that is highly effective is pollinating via the wind.

Pollen being released from a flower which will be carried by the wind. Plant Pollen is available through the CC0 Public Domain.

When the wind transports pollen it gets dispersed across the landscape, sometimes even getting caught within puddles. Inevitably, many pollen grains get caught in lakes and accumulate in the sediments. When it settles on the bottom of a lake basin, it stays there and is preserved for researchers to find hundreds, and even thousands, of years later. All this Read more
