This video was made to be funny, but now I want to know! What is this rock and why the sign?

No idea, but I'm guessing he might have missed the real point of interest.

The prairies are dotted with these glacial rocks which were rubbed smooth by the bison herds which used to be a predominant feature in the grasslands.

Makes sense that they were used as navigational devices by the First Nations.

Spent some of my high school summers as a tour guide at Head-Smashed-In Buffalo Jump so learned a a lot from some very good teachers at the site.

This is probably not the situation with the rocks in video but I found this tidbit interesting.

When we visited Mt. St. Helens, we learned that scientists learned a lot more about volcanoes because Mt St. Helens blew out the side of the mountain rather than straight up. When a volcano blows out the side it can spew rocks much much further than when it shoots them up. Turns out that there were geological mystery rocks that were mysteriously sitting very far from their geological origin. Once Mt. St. Helens erupted, they understood how those rocks might have been transported by an earlier volcanic eruption.

Cool! Very interesting! I did not know about the bison rocks, but I haven't been to Saskatchewan.
