Biface Preform

This week we feature an artifact found recently while conducting a survey for an Associated Aggregates gravel pit along the Nordegg River. The artifact is an irregular biface that is likely a preform. A preform is often an ovate or triangular shaped rock that has been flaked on both sides using percussion and pressure flaking techniques. This artifact was likely in the early stages of becoming some form of tool (e.g. knife or projectile point) before it was discarded by the flintknapper.

It is not clear why the flintknapper quit working on the artifact, the knapper may have made a mistake or did not like the stone material. The artifact is made from a unique red speckled chert with some fossilized plant remains embedded on the dorsal side of the artifact. We asked the consulting community if they knew what kind of chert the artifact was made from and Jason Roe, Lifeways Canada, identified the material as Paskapoo chert.

The artifact was found at a site identified by our clients, Dan Hill and Jodie Bauman, who were interested in the process of historical resource impact assessments (HRIA). While screening a shovel test, under the supervision of our archaeologists, Jodie found a large utilized quartzite flake. Further testing, revealed the site was over 200 m long and had evidence of fire (fire cracked rock) and tool making (biface).

Big John’s Spring

A couple of the traits that serve archaeologists best are curiousity and an ability to recognize when something doesn’t belong.

For example, look at this site Brittany found in 2014 on the North Saskatchewan River when we were undertaking assessments for Sundre Forest Products. It may not look like much at first glance, but it’s an interesting historic period site.

Brittany was riding her ATV along the recreational trail that follows the route of the historic Canadian Northern Western Railway line that ran between Nordegg and Rocky Mountain House. She was looking for the best place to park and begin her hike when she noticed a break in the berm that follows some parts of the rail line. It was a strange and deliberate looking design and so she stopped to investigate. Visible from the trail and through the berm was a small pool of water. Closer inspection showed the pool to be square shaped, lined with cut boards, and overflowing; the water was flowing out of the pool and down the slope away from the railway line. It must be spring fed for the water to be flowing like that.

We both walked through the surrounding area, looking for anything else that might be related to the site. We found some cans, part of a shovel and some other metal items. These things are common along the railway line. We saw that there was barbed wire fencing strung across the pool, probably to keep cattle in as this area has a history of grazing. Could this pool be a watering hole for cattle? Since the barbed wire ran right over the middle of the pool we decided that it likely wasn’t made for that reason. Perhaps it was a watering stop for the nearby railway. It may be a bit small for refilling a train (although we couldn’t safely confirm how deep it is). I think it’s more likely this water was used for human consumption.

We later found this story about the nearby town of Saunders Creek in the book Ghost Town Stories of Alberta1:

During the hungry Depression years, when there was very little work at the mine, most residents survived on garden vegetables, wild meat and fish from the North Saskatchewan River. Near his cabin, Big John discovered a way for townsfolk to keep their food and water supplies fresh… One day in 1932 while out walking, Big John discovered water seeping from a side hill. He climbed up a bit and dug a hole. As water began flowing into it, he realized he’d found a spring. He built a little shed around it to create a cooler. People stored perishable food there, and whenever the mine’s washhouse water line froze up, Big John allowed folks to help themselves to water. Over the years, it became a regular sight to see residents walking along Big John’s path from the creek, loaded up with as many buckets of water as they could carry.

Could this be the remains of Big John’s spring / cooler? We later found the remains of a cabin just 130 m down the slope from this pool (see photo below) so it certainly sounds like the same set up described in the history book.

Unfortunately, the location just doesn’t quite match up. Big John apparently lived close to Saunders Creek whereas this site is more than 20 km down the railway from Saunders. It could be a coincidence or an example of how good ideas spread.

To hear more about what we’ve been finding along this stretch of railway, join us on May 21st at the Sundre Museum for an Archaeology Roadshow.

Stone Drill

This week, we showcase a stone drill. That’s right, you guessed it, this type of stone tool is used to drill holes in things. Like knives and projectile points, drills are worked on both sides to create sharp edges and a narrow tip. Unlike other stone tools however, drills are very narrow and thick, and often are diamond shaped in cross-section. This design makes the drill stronger, and less likely to break. In Alberta, stone drills are often either long and straight, with a bulb or a “T” shaped base. More often than not, you find the broken end of drills, because they snapped off while in use. The stone drill bit would be attached to a long wood handle using sinew, rawhide, and pitch, and then spun to create the circular motion for drilling. This could be either done by hand, or using a small bow and string to spin the drill.

We found this stone drill while working for Sundre Forest Products in 2012, in the Foothills west of Red Deer. The artifact is made from a brownish-gray chalcedony, and also shows evidence that it was heat treated. The drill has small “potlid” fractures, where irregular pieces of the stone popped off. This type of break happens when a stone is quickly heated and cooled.

Radial Biface

Today’s picture comes from the Ahai Mneh site on the shores of Lake Wabamun, west of Edmonton, AB. This archaeological site has a long history of human occupation, from earliest hints of people in Alberta using Clovis technology, right up to the Late Precontact and Historic Periods. Featured here is a large radial biface, made of a fine-grained siltstone. This artifact was found in a field adjacent to the site, having been turned up by a plow. While not exclusive, radial bifaces such as this one are commonly associated with the Clovis tool kit, dating back to 13 000 years ago in Alberta.

Scottsbluff Point

Today’s picture comes from the Ahai Mneh site on the shores of Lake Wabamun, west of Edmonton, AB. This archaeological site has a long history of human occupation, from earliest hints of people in Alberta using Clovis technology, right up to the Late Precontact and Historic Periods. Featured here is a Scottsbluff point, made of classic Alberta quartzite. This projectile point type is part of the Cody Complex, which was present across North America between 9 000 and 7 000 years ago. Point such as this one are famously associated with large communal kills, where the hunters dispatched dozens of giant Ice Age bison in natural and built traps.

Late Precontact Arrowhead

Today’s picture comes from the Ahai Mneh site on the shores of Lake Wabamun, west of Edmonton, AB. This archaeological site has a long history of human occupation, from earliest hints of people in Alberta using Clovis technology, right up to the Late Precontact and Historic Periods. Featured here is a Late Precontact side-notched arrowhead, made of a fine-grained black siltstone, that likely dates between 1000 to 300 years ago.

End Scraper

Today’s artifact is an endscraper, a tool used to remove the flesh and hair from an animal hide. The person who made this tool took a small pebble, split it in half, and then chipped fine flakes off the one end to create a steeply beveled edge. The stone blade would then be attached to a handle, and dragged across a stretched hide to scrape the unwanted flesh and hair away. This artifact was found at the Quarry of the Ancestors site near Fort McMurray, and is made of a high quality chert.
