Wood Bison

While doing helicopter work near Zama City in 2014 we spotted a herd of bison. We were very surprised to find out that these impressive animals are not uncommon in the area. These Wood Bison are part of the Hay-Zama herd. What is exceptional about this heard as of 2015, there is no evidence of tuberculosis or bovine brucellosis. These diseases have been found in other wild herds in Alberta.bison fom heli_resized

If you are ever lucky enough to see these creatures in the wild, please remember that they are wild animals and can be extremely dangerous. We have heard anecdotal stories of people in the area honking their horn to encourage a slow bison to move off of the road, and the bison not taking too kindly to it.Bison from air_resized

It’s always important to stay highly visible and safe out there. While overhead hazards are not a concern at most archaeological sites, we often do work in places where banging your head and falling debris are a serious risk. One also needs to be careful when exploring historic sites, like this root cellar here. Often times, historic structures such as this can have pieces of metal farm equipment hidden in the tall grass. If you are not careful, you can run the risk of stepping on a rusty nail or the spikes on a set of harrows.

Our clients require us to carry fire fighting equipment including shovels, pulaskis, fire extinguishers and full backpack fire pumps, also commonly known as ‘piss packs’. At the end of a shift we decided to do a quick drill to make sure everyone knew how to use the fire pumps, which had the extra bonus of giving us a head start on washing the trucks.

Archaeology in the Fort McMurray Fire

At the end of June we started work on planned fire salvage harvest blocks for Alberta-Pacific Forest Industries, southeast of Anzac Alberta. This was the southeastern end of this springs massive Fort McMurray forest fire. When fire kills or damages a stand, there’s a limited time-frame within which the wood can still be salvaged for lumber or pulp. Planning for salvage started before the fire was under control. Once it was safe to do layout work we had a narrow window to get in and complete our Historic Resource Impact Assessment of the salvage plan before harvest operations would start.
As the Forest Management Agreement holder for most of northeastern Alberta, Alberta-Pacific Forest Industries has a long-term right to harvest aspen and poplar for their pulp mill north of Athabasca. This long term land tenure comes with a lot of responsibilities. These include a responsibility to salvage as much timber as they can from wildfires, and a responsibility to complete historic resource impact assessments of their operations.
The Historic Resource Management Branch of Alberta Culture understands that fire salvage is not part of a forest company’s normal Annual Operating Plan. It’s often difficult to know the final block boundaries until harvest is complete because the timber has to be damaged by the fire, but not too burned. There is therefore some concession given for late-season or last-minute salvage plans, which can be deferred to post-harvest impact assessment the following season.
In this case, Al-Pac wanted to ensure due diligence by completing their HRIA’s prior to salvage, so we started our fieldwork immediately after the layout crews finished putting up their block boundary ribbon. Fire salvage can be both a challenge and an opportunity for historic resource management. In addition to the logistical challenges of the narrow timeframe and uncertainty, working in a fire stand increases some safety hazards. There is of course the risk of holdover fires or flareups. There’s also an increased risk of blowdown from snags (standing dead trees) with their roots burned out and hangers (fallen trees and limbs hung up on other trees). Foresters call these “widowmakers” for a reason. There is often increased bear activity as they take advantage of the fresh green growth, grubs, and in later summer berry production, made available by the fire.
Forest fires also increase the risk of impact to archaeological sites. Forest harvest operations are normally pretty low impact, as far as archaeology is concerned. Feller-bunchers and skidders have large tracks and wheels to keep their footprints light. Under normal conditions, harvest leaves some tracks and trails, but the thick moss and duff of the boreal forest protect buried archaeological sites from a lot of the potential disturbance. A hot ground fire burns off much of the moss and duff, leaving the shallowly buried artifacts typical of the boreal forest much more vulnerable to exposure and displacement.
This factor is also what makes some fires an opportunity for archaeology. One of the hardest parts of doing archaeology in the boreal forest is the fact that everything is covered by a mat of moss, with almost no surface exposure. The only way to find sites is to dig labour-intensive shovel tests, and these provide very limited windows into the buried past. In a hot fire, the moss has been burned off, and we can see a much larger window. In some cases, scatters of artifacts, in-situ (in place) where they were left thousands of years ago, are sitting on the surface.
That wasn’t the case this week. We found a couple of sites where the fire didn’t burn quite that hot, including a probable Besant point, but we had to dig for them, as usual.
I also found a renewed appreciation for the resiliency of the boreal forest, and how well it’s adapted to a frequent fire regime. It’s only been two months since the fires burned through the area, and most of the burn is covered in a lush green carpet of fresh growth. Plants like fireweed, sasparilla, wild rose, raspberry and bunchberry have sprouted from root systems protected from the fire. Aspen and poplar suckers with huge deep green leaves are already knee to hip high. Insects are present in abundance, birdsong can be heard, deer and moose sign shows they’ve returned, and we saw a black bear sow with two cubs.

By salvaging the burnt timber, Al-Pac will help to fast-track that cycle of renewal, and will leave other areas they’d planned to harvest to grow for another season or two. By having us complete our historic resource impact assessments before harvest, we’ve identified and protected two potentially significant archaeological sites in an area that’s still pretty poorly understood. These are some good examples of how the forest industry plays an important role in Alberta’s woodlands, helping to manage multiple values on the landscape, and balance their operations with ecological and cultural concerns.

It’s that time of year again! The bears are waking up and the field workers are heading into bear territory. One of our archaeological field crews encountered this little guy in 2013 and found that he was a little less scared of them than the average bear.

Usually bears are skittish and will leave the area as soon as they know humans are around, especially if you have a noisy ATV running but this bear was a bit curious and stuck around long enough for a photo shoot. The crew scared him away and didn’t have another encounter. Remember to review your bear awareness training before heading into the bush for work or play!

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!
