Today’s picture comes from the Ahai Mneh site on the shores of Lake Wabamun, west of Edmonton, AB. This archaeological site has a long history of human occupation, from earliest hints of people in Alberta using Clovis technology, right up to the Late Precontact and Historic Periods. Featured here is a large radial biface, made of a fine-grained siltstone. This artifact was found in a field adjacent to the site, having been turned up by a plow. While not exclusive, radial bifaces such as this one are commonly associated with the Clovis tool kit, dating back to 13 000 years ago in Alberta.
A lot of our work is located very far back in the boreal forest. It is not uncommon to have the only trail that gets close to our target areas be blocked by a fallen log. During hunting season, hunters usually clear these trails. But the rest of the summer it is up to us. Several of our crew members participated in a Chainsaw training course. We learned to how to properly maintain our equipment and how to safely operate the chainsaw. We had the opportunity to practice our skills by making small chairs from the logs.
There is a lot of PPE involved! We are sporting the stylish chaps, the fancy face cage, and the comfy ear muffs. We also need to be mindful of where our legs are so that we don’t accidentally get them in the way!
This week we feature a picture of a biface found near Slave Lake, AB, a common stone tool in Alberta. The term biface is a generic stone tool classification, and simply refers to any thin piece of worked stone that has been flintknapped on both sides, or faces, of the artifact. So it can include tools like knives, arrowheads, and spear points, and certain types of cores. This biface is made of a fine-grained quartzite, and has been extensively worked around the margin to create a sharp cutting edge. The artifact exhibits a waxy luster, or sheen, that may indicate that it was heated to improve the quality of the raw material. Similar bifaces have been found in the foothills region and argued to be diagnostic of, or firmly associated with, the early middle period (5000 to 7500 BP) and referred to as Embarras Bipoints (Jason Roe, 2009, “Making and Understanding Embarras Bipoints: The Replication and Operational Sequencing of a Newly Defined Stone Tool from the Eastern Slopes of Alberta”).

Advances in remote sensing technologies and industry-driven initiatives have precipitated the wide scale production of lidar-derived digital elevation datasets in Alberta. These high-precision terrain models have been instrumental for cultural resource management strategies and the identification of new archaeological sites in the province. Lidar has proven to be extremely useful in targeting of distinct landforms and topographic features present on the landscape, and in the development of archaeological predictive models. While most lidar analyses for archaeological site predictions are focused on the modern landscape, these datasets can also be used to identify ancient landforms that may have been more suitable for human habitation in the distant past. Review of lidar data from the Lesser Slave Lake region in northern Alberta revealed numerous strandlines, meltwater channels, and relict beaches related to changing levels of proglacial lakes in the lake basin. These previously unmapped topographic features reveal a fluctuating landscape during the early period of human occupation in the province, and provide an opportunity to identify potential locations of ancient sites around the Lesser Slave Lake basin. A combination of reconstructions of proglacial lake levels using strandline elevations and current predictive modeling techniques was used to identify locations reflective of this past landscape with high archaeological potential for sites. This information will be used to direct future surveys in the region, to identify archaeological sites that might otherwise have been missed by cultural resource management programs.
Home away from home. Sometimes staying in town or at a work camp isn’t practical and we have to do it ourselves. After a hard day’s work in late September the crew is enjoying their evening meal of smokies and s’mores.
Today’s picture comes from the Ahai Mneh site on the shores of Lake Wabamun, west of Edmonton, AB. This archaeological site has a long history of human occupation, from earliest hints of people in Alberta using Clovis technology, right up to the Late Precontact and Historic Periods. Featured here is a Scottsbluff point, made of classic Alberta quartzite. This projectile point type is part of the Cody Complex, which was present across North America between 9 000 and 7 000 years ago. Point such as this one are famously associated with large communal kills, where the hunters dispatched dozens of giant Ice Age bison in natural and built traps.
Safety is key! Every spring we spend a full day preparing for the upcoming season. In 2015 we decided to review some of our safety training. Brittany is using an expired fire extinguisher to get a feel for how to use it in an emergency situation.
