Once we have surveyed our targets and evaluated any sites we have found, it is time to return to the office. All of our notes are taken on an ipad in the field. Now all we have to do is export our notes into a database which eliminates the hours spent on data entry.
Note taking is extremely important for archaeologists (Figure 1). The notes supply researchers the context of the artifacts. In this case context means the precise location of the artifact and it’s association with other artifacts and landscape features. This helps researchers determine such things as the relationships between artifacts on a site, it’s position in time and space, and even how it is related to different archaeological sites (Figure 2). Without notes and proper excavation methods, the context in which the artifacts were found is lost forever, and the artifacts have little scientific or interpretive value.
We also catalogue all of the artifacts that were collected in the field. We take measurements, weights, and note details such as material and artifact types, and enter them into a database (Figure 3). This along with the site notes gives us the information we need to write our reports.
In the final stage of the Historic Resources Impact assessment, we compile a report of all the work that we have done and submit it to our clients and the government. The report identifies which developments need to be modified to avoid impacting significant archaeological and historic resources. The site information is included in a government database of all the sites in Alberta as a reference for future industry development as well as researchers. This minimizes the impact that our clients have on Alberta’s history while preserving the past for future research and education.
When we identify a site, we conduct further evaluative testing to determine the type, character, and extent of the site. This is done according to government guidelines, and depends on the type of site, and the type of landform. If the landform allows for it, testing occurs in each cardinal direction or in a grid. Some sites are found on ridges or point terraces, and so in these cases, it is not possible to test in all directions (Figure 1).
Tree Time’s standards are that there must be three negative tests spaced at most 10 m apart in each direction from any positive. Sometimes additional tests are required in order to determine the significance, the size, and type of the site. For example if none of the evaluative tests were positive, further testing might be done at closer intervals to better determine the significance of the site. In addition to rigorous note taking, we also map and photograph the site (Figure 2).
The evaluation of the site is an important step for two main reasons. The first is to enable the government to maintain an accurate site database and to better inform future researchers of the size and type of sites are in the area (Figure 3).
Secondly, in this stage we determine the extent and significance of the site. If a client decides to avoid the site, delineation allows us to more precisely buffer the site. This is important because it allows the development to occur as close to the original plan as possible while still avoiding impacts to the site. In addition, if a client chooses to mitigate their impacts to the site through excavation, a more detailed evaluation of a site allows us to better predict the productivity of the site, and to render cost estimates of any mitigation work more accurately.
Once we have surveyed our targets, evaluated any sites we have found, and have finished our notes, it is time to return to the office (Figures 5 and 6).
The first step of a historic resources impact assessment (HRIA) happens in the office. Once we have the plan for a development, we need to assess whether the footprint will impact any recorded sites or if it has the potential to impact any unrecorded sites. We use our experience and knowledge of archaeology, GIS data, and databases of recorded sites in order to identify high potential areas that might have any archaeological and historic resources (Figure 1). Although this stage of archaeology does not capture the imagination of the public and isn’t very exciting or glamorous, it is the most important part and the foundation of our work.
High potential areas vary by region, depending on the geography and the history of the area. Generally areas that people would camp or travel through are considered high potential; these include well-defined landforms and areas near water. We also take into account the environment of the past. For example, shorelines fluctuate, and rivers and streams may change course or dry up. Areas near water generally have higher potential because they were used as a method of transport, offered fishing opportunities, and, of course, they were also a source of fresh water (Figure 2).
Sometimes a development plan will conflict with a previously recorded site. In this case, we can recommend either that the development plan be changed to avoid the site, or that impacts to the site be mitigated by excavation. If there are no recorded sites in the footprint, but there are areas that we think are likely to have sites, we recommend field survey. Using GIS data and the research that we have complied concerning the area around the developmental footprint, we create targets of high potential areas to survey in the field. The next step takes us out of the office and into the field.
Do you think she’ll start? While surveying harvest blocks in the Marten Hills by Slave Lake, we found an old car parked on the side of an old overgrown road. While not as unique an old plane crash, it does show how much an area can change. What used to be a road is now an overgrown trail through the forest.
The most common career in archaeology is that of a consulting archaeologist. Consulting archaeologists work in the field of Historic Resource Management or Cultural Resource Management (CRM). People in this line of work generally work on Historic Resource Impact Assessments of planned developments before construction is started. The responsibility of consulting archaeologists is to identify historic resources and make recommendations as to how to manage those resources when they might be impacted by proposed developments. Most work conducted by consulting archaeologists is archaeological survey, rather than excavation. This work is typically done between the months of May and November and the winter months are spent writing reports. In some jurisdictions (northeastern British Columbia for example) field work can continue year-round with adaptations made to conduct work during the winter months. Supervisors and project managers typically have a Masters degree level of education. There are often seasonal positions for archaeologists with a Bachelor’s degree.
Some archaeologists work in universities as professors who teach classes during the school year. Over the summer and throughout the year they publish articles about their research. This may involve conducting detailed excavations of known archaeological / historic resource sites to learn about the lives of people in the past and to answer research questions. Some academic archaeologists focus on artifact reproduction and other experimental techniques to learn about past lifeways, while others use scientific methods such as isotopic analysis or ancient DNA to learn about specific topics, for example past human migration and diet. Academic archaeologists tend to do less field work, and often because they are restricted in time owing to teaching responsibilities they revisit the same site to excavate for short periods year after year (for example L’Anse aux Meadows was excavated over the course of eight summers). The focus of academic archaeology tends to be more theoretical and analytical work. Archaeologists working in universities generally have a PhD level of education and post-doctorate experience.
Jobs in museums are less common for archaeologists but do exist. These archaeologists work as curators creating exhibits at the museum for the general public, lead tours of the museum and special collections and conduct research and publish journal articles of their findings. Research projects done by museums tend to be smaller in scale than those done by universities as funding is less available (university research is often funded by grants that are only available to students or academics) and free student labour is harder to come by. Conservators are specialized archaeologists who work to preserve artifacts and maintain optimal storage conditions for those artifacts (appropriate humidity and temperature are examples). Most artifact conservation positions are at museums. Conservators often do a more in depth analysis of artifacts after they are received at the museum than the researcher may do as they need to know the exact chemical make up of the artifact in order to best preserve it. An archaeologist may only need to state in their research that an artifact is metal, but a conservationist needs to know exactly what kind of metal that is to best protect it. Conservators often have a background in archaeology but attain specialized graduate degrees in conservation or museum studies specifically related to conservation of artifacts. These positions are usually held by persons with a Masters degree or PhD.
The provincial government employs archaeologists to oversee the work of the archaeologists within the province. Archaeologists working for the government review permit applications, grant archaeological research permits and they review the work of the consulting and academic archaeologists by means of a review of the reports submitted upon the completion of a project. The folks at the government provide guidance to field archaeologists and manage the Archaeological Site Inventory, where all the site information is submitted and compiled into a searchable database. The federal government also employs a handful of archaeologists to do research projects. These research projects are usually done though Parks Canada or the Canadian Museum of History. A recent example is the underwater archaeological investigation to find the missing ships from the Franklin expedition. These positions are usually held by persons with a Masters degree or PhD.
We get to do a lot of traveling around Alberta during the summer. Sometimes when time permits, we get to stop at local attractions. During a recent trip to Fort Vermilion we made a stop at St. Louis Catholic Church in what is locally referred to as ‘Buttertown’. This church was built in 1906-1909.
Check out the Fort Vermilion Heritage Center website for more information about the church and other attractions in the area
In the summer of 2013, Vince and I were walking through a harvested cutblock south of Slave Lake and we noticed something big and white on a high hill along the tree line. At first we thought it was some sort of tarp but as we got closer we realized it was the broken tail portion of an airplane. We were both pretty excited to find the wreckage because a plane crash is something we don’t find everyday.
We documented the site with photographs and mapped it as we would a normal historic site. We found pieces of the wreckage scattered over 100 m along the hill. The site seems to be a local hangout as evident by the bullet holes in the tail and several beer cans scattered around the wreckage.
Thankfully the registration number, C-GWYD, was still visible on the tail portion and were able to learn more about the crash. On December 29, 1975 a Beechcraft 99 en route to Peace River from Edmonton crashed into a high hill overlooking Slave Lake to the north. The plane came to a rest upside down and sadly both pilots, Captain Bill Groesnick and Co-pilot Banshi Ghelani, were killed upon impact. However, all seven passengers survived with minor injuries.
When discussing historic resources we often attribute it’s value to the age of the site. The Slave Lake plane crash site, while only 40 years old, demonstrates that something can have historic value because of it’s significance to a local community or a historic event.
