I’ve submitted a poster for the upcoming CAA conference in Whitehorse, Yukon in May. Check out my abstract and check back for research updates on our blog!
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.
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 Late Precontact side-notched arrowhead, made of a fine-grained black siltstone, that likely dates between 1000 to 300 years ago.
Today’s artifact is an endscraper, a tool used to remove the flesh and hair from an animal hide. The person who made this tool took a small pebble, split it in half, and then chipped fine flakes off the one end to create a steeply beveled edge. The stone blade would then be attached to a handle, and dragged across a stretched hide to scrape the unwanted flesh and hair away. This artifact was found at the Quarry of the Ancestors site near Fort McMurray, and is made of a high quality chert.
Featured picture this week is a bifacial knife, with fine retouch along the right margin to create a sharp edge. This knife is made from Knife River Flint, a stone material that can only be found in North Dakota, USA. Today’s artifact was found 70 years ago in Manitoba, Canada.
