Weather can change very quickly in the foothills. From one day to the next, and within the day itself.
The following photos were taken all on the next day.
The weather can also change a lot depending on your elevation. In order to get out of the valley we were in we had to drive up and down a mountain pass. There was a lot more snow at the higher elevation than where we were working There was no snow on our drive in that morning.
If you spend a lot of time outdoors, either for work or for pleasure, you learn that the weather can change very quickly. You also become aware of how unforgiving mother nature can be. That is why it is so important to carry the right gear and to know some basic survival skills in case things go south.
This spring we took a survival course through Three Ravens Bushcraft. We learned how to make a warm bed to sleep in and brushed up on our fire making skills.
These skills are great to know and could save your life in an emergency. However, the best way to stay safe, is to try to avoid the situation in the first place. You can do this by preparing for your trip in advance. Make sure people know where and for how long you plan on going. Plan your route and check the weather reports. Also take into consideration changing weather conditions and alter your plans if need be.
The above photo was taken on May 24 2017, the temperature was closer to plus 18° C the day before. We knew this storm was coming a couple of days in advance so we were prepared for it.You can also check out Alberta parks website for hiking and back country safety tips.
Living in Alberta, we all know how disastrous a forest fire can be. Some of you might have been personally affected by the devastating fires in Fort McMurry or in Slave Lake. Brian knows personally how dangerous forest fires are because he used to be a forest firefighter. Many of us at Tree Time have walked though the remains of a burned forest and have seen what is left behind.
So when Brian and I were working the in foothills around Rocky Mountain house and we saw the remains of a smouldering fire, we took it seriously.
We noticed the smoke in the morning as we walked to our first target. The campfire had been abandoned, likely by people camping during the May Long weekend. This means it was likely burning unattended for three days. It looked like people had been burning garbage in the fire pit, including a mattress. The mattress frame was smoking heavily. The ground around the campfire was also smouldering a bit, and somewhat hot. The area around the pit was clearly burnt.
We put out the frame with water from a nearby creek. It was so hot that it caught fire again as soon as the wind touched it. Back at the campfire, we used our shovels to dig up the earth around the firepit and in the pit itself. Brian told me that he had fought many fires during the May Long weekend that started in this exact way. Not because of people burning garbage, but because of abandoned fires. People might think that they put out their fire, but debris (roots, moss etc) on or under the ground can catch on fire and spread the fire beyond the stone rings. You can see in the pictures that the area around the campfire has been burned.
That is why it is so important to make sure that you have properly put out your fire. Please check out the Alberta Parks Website for great advice on campfire safety.
Also if you need to report a wildfire, call 310-Fire (3473). Never put yourself in danger.
We thought we would share this story in advance of the long weekend to remind people about campfire safety. Alberta is a great place and camping is an amazing way to experience it. So from us at Tree Time, we sincerely wish you a great long weekend and happy, safe camping.
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.
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.
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.
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.
