Ground Penetrating Radar

Ground-Penetrating Radar (GPR) is the process of sending radiowaves through the ground. As these radiowaves pass through the ground, any change in the subsurface materials will cause some energy to be reflected back to towards the surface while the remaining energy continues deeper. This information is recorded by a receiver which records the time it

Atlatl

An atlatl is a throwing stick with a small hook used to throw darts (projectiles). It allowed the hunter or warrior to create more leverage to increase the speed and distance of the dart. This weapon was used throughout North America including Alberta, approximately between 7,500 and 1,350 B.P.

Glacial Flutes

Ryan is doing layout work to protect wetlands and streams during aerial herbicide application and he got this great shot of glacial fluting northeast of Calling Lake. These parallel ridges were formed when the Laurentide ice sheet coming southwest from the Canadian Shield hit bedrock uplands at the east end of the Pelican Mountains. The

These tools are thought to have been used to split organic materials like wood and bone, much like an ancient stone chisel.

Conch Shell

At our Archaeology Roadshow event in Lac La Biche, in fall 2015 Allan and Juanita Gaudreault brought in several conch shell fossils. These shell fossils were heavily worn and most were down to the central spiral. This made them difficult to identify at first. These are very unusual specimens because these type of marine shells

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

Bone Needle

This week we showcase a very unique artifact, a bone needle.  This tool is very long and thick compared to the modern steel needles that we are more familiar with, but it still very sharp at the tip. The eye of the needle is diamond-shaped and tapered, which shows us that the eye was made by

End Scraper

This week we feature a stone tool found upstream on Fall Creek, about 55 km west of the community of Caroline, AB. We were undertaking an assessment for Sundre Forest Products and testing a flat area overlooking the creek (shown below) when Ryan found the end scraper shown above. A “scraper” is a type of

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
