The Brazeau Reservoir Archaeological Survey Project

The Brazeau Reservoir Archaeological Survey is a project hosted by the Strathcona Archaeological Society, and is sponsored by Tree Time Services. It currently is centred around a large campsite and workshop on the upper valley margin at the confluence of the Brazeau and Elk Rivers, located near Drayton Valley and Rocky Mountain House.

The main site, FfPv-1, was found in 2009 by Sandy and Tom Erikson while out on a day hike. They contacted the Royal Alberta Museum to report their finds, and the site was visited by curators Jack Brink and Bob Dawe in 2013. They conducted an exploratory survey with Sandy and Tom, and found five additional sites, FfPv-2 to 6. These sites are all located around the edge of the upper water lines of the Brazeau Reservoir, and are covered by water for most of the year.

Jack and Bob brought these sites to the attention of the Strathcona Archaeological Society as an opportunity to engage with the society’s members through the practice of archaeology. What made these sites perfect to use for a volunteer project is that all the sites were identified by the artifacts found on the surface, thanks to the reservoir water that slowly stripped the soil away. This meant that volunteers could learn how to spot the artifacts sitting on the surface.

In 2015, Madeline Coleman, one of our Permit Archaeologists, co-organized the pilot volunteer project with another SAS member, Amandah van Merlin. Volunteers travelled across FfPv-1 to figure out the site’s extent, and what type of site it was. Survey of the landforms around FfPv-1 found three new sites!! Volunteers also found projectile points that crossed almost the entire expanse of Alberta Precontact history. The cultural phases represented include Clovis, Agate Basin, Hell Gap, Oxbow, and Plains Corner-notch.

Based on the location of the sites, it is very likely that the sites are located around the whole reservoir! The construction of the reservoir began in 1910, long before developments in Alberta were examined for impacts to archaeological resources. Currently, many of the sites recently identified are only accessible by boat.

A new survey with test excavation units are planned for May 28th and 29th. To register or for more information, email Madeline at [email protected]

Oxbow Dart Point

Today’s picture is brought to you from the Peace River Trail. It is a nearly-complete Oxbow dart point, made of a medium-grained quartzite. Dart points are larger than arrow-heads and were used on long spears that were thrown using an atlatl. The atlatl gave the thrower extra force than when using a spear. An Oxbow point is recognized by it’s “Micky Mouse ears” that form the base of the point, and is one of the most easily identifiable point types. The Oxbow Phase dates between 4500 and 4100 BP (Before Present), and is part of Alberta’s Middle Precontact Period.

This Saturday, April 9, 2016, Tree Time archaeologists will be giving a presentation on some of our survey results in forestry developments along the historic Peace River Trail, which is located on the north shore of the Athabasca River between Smith and Sawdy, AB. This trail is now the modern Peace River Wilderness Trail, a part of the Trans Canada Trail mission, and follows approximately the same route as the historic trail. Originally, the historic trails in the area were created by Aboriginal people, using the Athabasca River as a major corridor, either by foot or canoe, and later by horse. As Europeans began to traverse the same areas, whether it be for trading, homesteading, or exploring, they would follow the same trails, rather than create new ones. Over time, the Peace River Trail became wider and well-traveled, with small reroutes as people forged new trails around areas that became impassable.1 bridge DSCF1420_tsl_2014

Archaeological survey along the trail, beginning in 2006, has identified 19 sites with one or more prehistoric, historic, and contemporary components. These sites indicate the trail has been in use continuously over time. However, giving dates to these sites and determining how long this area, and possibly the trail, has been used for is very difficult because we do not often find items that can be placed during a specific time frame. Tree Time has been fortunate that during our 2013 and 2014 field seasons, we found one site that can be confidently dated to the Middle Precontact Period (4500-4100 BP), and one site to the historic period, with contemporary use.

At the historic site, GgPj-1 we found an older segment of the historic trail that has not been heavily used for some time. We even found evidence of wagon ruts! Directly along the path we found a tree blaze (a tree that was marked by removal of some of its bark). By coring the tree, we were able to determine that the tree blaze was made around 1958 AD. Only a few steps off the trail, we found a land survey pin with the typical four holes placed evenly around the pin. Starting in 1910, the Alberta Township System was implemented, following a method very similar to the Dominion Land Survey system. This site, although not exactly along the present-day designation of the township system, is only approximately 200 m off.

At the second site, GhPj-12, we found a nearly-complete quartzite Oxbow dart point. The Oxbow cultural phase dates between 4500 and 4100 BP. The site is located 700 m southwest of the modern Peace River Trail, right along the Athabasca River upper valley margin. The landform itself is very flat with excellent edges along the sides, and a little erosion at the point. Finding the Oxbow was clearly a moment of luck because only two artifacts were recovered from GhPj-12! Out of the 17 shovel tests we placed around the site, only one shovel test contained artifacts.

To hear more about how these two sites, along with other sites in the area help us piece together the history of the Athabasca River and the Peace River Trail, come check out our Roadshow at the Boreal Centre in Slave Lake, AB, April 9th (1-5 pm) We will have a Stones and Bones session, where you can show us your finds. Don’t forget to try your hand at Atlatl throwing, one of the hunting methods used during the Middle Preconact Period, including the Oxbow culture!

Chainsaw Training

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!
