Someone mentioned teepee rings, these are so prolific on the prairies it’s amazing. I found one at the base of yamnuska too. Once you get the “eye” for them they start to pop up a lot.
These napped points tell the story of how much travel and trade went on between the First Nations before Europeans arrived.
The distances that had to be walked before horses were brought by the Spanish into North America in the 1500's is hard to appreciate.
The location of the stone deposits to the places these arrow heads are being found had to be a whole summer's walk for the groups who were trading finished product and hunting Buffalo on the prairies.
I was surprised when some relatives had a large arrow head collection off their farm just south of stony plain about 5 miles . I guess they used to find them along the fence line . maybe when they were installing the fence in the fields.
I believe they were the first homesteaders on that farm . Land must have been free back then ,if you just farm it .
