2550 – 1400 year old projectile point!

This week we present one of the artifacts from a site we found while doing surveys for Sundre Forest Products on the North Saskatchewan River in 2015. More than 30 artifacts were found through shovel testing at the site, but this one is extra-special. It’s a dart point of the Besant style. Above is a photo of the point right after Corey found it in the screen we use to sift soil from the shovel tests we dig while looking for sites.

One reason this artifact is so special is because it helps us estimate how old the site is. We don’t have a precise date for when people were at this site because that usually requires finding an artifact made of material that was once living, like wood or bone, that can be sent to labs to be dated through special techniques. Unfortunately these kinds of material don’t preserve well in the acidic soil of the Boreal forest, but by finding a point like this we can give an estimate of the site’s age. Besant points have been found in Alberta at sites dating between 2,550 and 1,400 years ago. That means that before this photo, the last time the point was seen may have been more than two thousand years ago!

In addition to being one of the few artifacts we find that can be used to figure out how old a site is (and teach us about how people were living in the past and how that changed over time), this artifact is special because we don’t find points often. Most people have seen arrowheads like this at some point, but they’re not commonly found when archaeologists are at the test pitting stage of their work. Instead, we usually find all the rock that gets broken off when the past person was making the tool. We call those pieces “flakes” and there are way more flakes out there than points. That’s why it’s always a big deal to find a point through shovel testing. Look how happy Corey is at finding it in one of his shovel tests!DSCF2440_resized

 

Agate Basin Spear Point

This week’s photograph is of an artifact we found in 2015 when undertaking an HRIA for Sundre Forest Products. It comes from a site south of the Ram River – our 100th site of the year, in fact. It’s an exciting find: a spear point of the Agate Basin style. The picture above was taken when it was found and the picture below shows the point after it was catalogued in our lab. We have found our fair share of points over the years, but this is a rare one because of its age. Agate Basin points are some of the oldest found in the province and date between 10,200 and 9,600 years ago.

FbPu-31_8_IMG_0106The site was identified when we were surveying a disturbed area. Like Corey explained in his blog entry, a lot of information may be lost when a site is disturbed because the relationship of one artifact to another has been disturbed. Although we always hope to find sites intact and undisturbed, disturbances like erosion can allow archaeologists to see a larger area of soil than through shovel testing alone. This artifact was found lying on the ground when we were walking over a ridge. This is why archaeological assessments in disturbed areas can be worthwhile. It’s also why archaeologists are hard to walk with – they’re always looking down, searching for artifacts in even the most unlikely places.
