Sometimes you just can’t win!

Digging in the forest we are always encountering tree roots. It’s a great test when you miss them all. Most days your shovel is sharp enough that you hardly notice the roots as the shovel blade slices through them. Sometimes you have layers of roots, which work as a group to form a wall. You can “smash” through them with a bit of effort, one root at a time. And then there are days like pictured here! Your shovel just won’t go through or you don’t have the energy to “smash” through them, so you have to break out the big guns! I like to carry a folding saw with me in my vest, so roots like these won’t get the better of me! Unfortunately these ones did. So I just dug around them.

Introduction to CRM Part 4: Evaluating a Site

When we identify a site, we conduct further evaluative testing to determine the type, character, and extent of the site. This is done according to government guidelines, and depends on the type of site, and the type of landform. If the landform allows for it, testing occurs in each cardinal direction or in a grid. Some sites are found on ridges or point terraces, and so in these cases, it is not possible to test in all directions (Figure 1).

Tree Time’s standards are that there must be three negative tests spaced at most 10 m apart in each direction from any positive. Sometimes additional tests are required in order to determine the significance, the size, and type of the site. For example if none of the evaluative tests were positive, further testing might be done at closer intervals to better determine the significance of the site. In addition to rigorous note taking, we also map and photograph the site (Figure 2).

The evaluation of the site is an important step for two main reasons. The first is to enable the government to maintain an accurate site database and to better inform future researchers of the size and type of sites are in the area (Figure 3).

Secondly, in this stage we determine the extent and significance of the site. If a client decides to avoid the site, delineation allows us to more precisely buffer the site. This is important because it allows the development to occur as close to the original plan as possible while still avoiding impacts to the site. In addition, if a client chooses to mitigate their impacts to the site through excavation, a more detailed evaluation of a site allows us to better predict the productivity of the site, and to render cost estimates of any mitigation work more accurately.

Once we have surveyed our targets, evaluated any sites we have found, and have finished our notes, it is time to return to the office (Figures 5 and 6).

Spruce Grouse

Can you see them? I almost didn’t! These spruce grouse chicks were hanging out on a trail we were walking on near Wabasca-Desmarais, Alberta, nested in the woody debris on the trail. The only reason we stopped was because we saw the mother hen making short flights down the trail and making a lot of noise. Often, the grouse mothers will fake an injury and make a lot of noise to draw predators away from their chicks. Luckily for her, we weren’t hungry that day!

Atlatl Point

This little quartzite projectile point comes from a small site near Wabasca-Desmarais, Alberta. We found it on a small hill that was next to a lake, along with several chert and quartzite flakes. This point likely was fitted to an atlatl dart, a type of feathered throwing spear that uses a hooked throwing stick to help propel the projectile.

It is difficult to tell how old this particular projectile point is. It has a straight base and broad side-notches, which is similar to the Besant Phase (2500 to 1000 years ago on the northern plains), but it is also similar to some of the early side-notched points from the Middle Precontact (8000 to 5000 years ago). Looking further to the north, this stone point also has some similarities to the kind of projectile points found in the Taltheilei tradition in the Northwest Territories. Unfortunately, we do not have a clear understanding of projectile point typologies in the boreal forest of northern Alberta, as this region is lacking deeply stratified archaeological sites with material that we can radiocarbon date.

Antique Car?

Do you think she’ll start? While surveying harvest blocks in the Marten Hills by Slave Lake, we found an old car parked on the side of an old overgrown road. While not as unique an old plane crash, it does show how much an area can change. What used to be a road is now an overgrown trail through the forest.
