|1/3. Students excavate a small section of the Fincastle bison-kill site.|
A massive and rather cunning bison kill carried out some 2,500 years ago among the sand dunes of southern Alberta left behind a wealth of artifacts that are offering new insights into a poorly-understood culture of the ancient Northern Plains.
In addition to the scattered remains of at least 65 bison, archaeologists have found more than a hundred stone points, most of them fashioned from a type of rock found only in North Dakota, a thousand kilometers away.
And beneath the layer of animal fragments and tools, even more rare finds were discovered: eight arrangements of bison bones found standing on end, perched in precise, almost sculptural patterns. [...] westerndigs.org
