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.

Finding Tertiary hills clinker in alberta
Needle in a haystack Tertiary Hills Clinker is a natural rock that is formed when coal seams burn underground and melt the surrounding sediments. Lightening and forest fires can ignite exposed seams of coal, which burn hot enough to turn clay and sand into a near-glass like material that is suitable to make stone knives,Keep Reading

How are archaeological sites buried?
So much dirt! One of the most common questions we are asked is: “how are archaeological sites buried?” and “Where does all the dirt come from?” It doesn’t make sense for layers of dirt to be covering the world deeper and deeper over time, right? Well, that’s because it’s only part of the story. DidKeep Reading

Lanceolate Bifaces of The Interior Plateau, BC
Spear Points in the Forest In the summer of 2022, archaeologists Braedy Chapman and Fallon Hardie conducted archaeological impact assessments (AIA’s) on emergency wildfire rehabilitation developments. These developments were constructed to manage the spread and impact of wildfire throughout the Interior Plateau of British Columbia. Long stretches of forest have been scraped or bladed toKeep Reading
