The elders of the Wahpeton Dakota Nation had long prophesized that the return of the plains bison to their ancestral lands would portend a welcome turn of events for Canada’s First Nation peoples. They may not have known, however, that it would take just eight months for this prediction to come true.
In December 2019, officials at Wanuskewin Heritage Park in the province of Saskatchewan reintroduced bison to the region more than a century after the animals were hunted to near extinction. The following August, the herd’s hooves uncovered four petroglyphs, or rock carvings, and an accompanying tool used to create the ancient artworks.
Archaeologist Ernie Walker and bison manager Craig Thoms made the find last summer while visiting the park. They were standing near a wallow, or a vegetation-free spot where the bison give themselves dust baths, when Walker noticed a grooved rock protruding from the ground. Assuming the cut was from tool damage, he brushed away the dirt, only to expose another groove and then another. “They were all parallel, all symmetrical,” he says. “It was at that point I realized this [was] actually what is known as a petroglyph. This was intentionally carved.”
The 550-pound boulder turned out to be a ribstone, so called because it’s engraved with motifs that represent bison’s ribs. Researchers found three more carvings over the ensuing weeks: a larger stone with a grid pattern, a small specimen with pits and grooves, and a 1,200-pound boulder covered in lines. Then, most surprisingly of all, the stone knife used to carve the petroglyphs resurfaced.

What I find amazing about petroglyphs is that not only did the natives make the tools to produce such engravings - but apparently had the free time to do so. Obviously, such endeavors were of great importance to them.
