Head-Smashed-In ... Maths

In 1979, with a friend and still one of four (yes - I know!) we went to Calgary, Alberta for three weeks.

This was a key holiday, one to remember. I was able to return in 1989, with my then wife, eldest son and the (very) youngest - at the time - as we learned. With a new edition of the same tourist map, it was amazing to see the change in the cities footprint across a decade.

Our travels supported by the love and hospitality of two Brits who emigrated to Canada, sadly no longer with us. We talked of migrating for a time: Canada, or New Zealand.

In Alberta, one trip took us past:

Head-Smashed-In Buffalo Jump (and photo source)

Ever since school, it is maths that has head-smashed-in mine. The (personal) history here revolves around the Eleven-plus exam [ https://en.wikipedia.org/wiki/Eleven-plus ] which I failed.

Yes, that's -'11+' - I'm sure you can see the irony?

Perhaps, in the near future the future will resolve around the diagrammatic form of Hodges' model and the model's acting as a baton to pass to others with the knowledge and skills to apply mathematics and logic to Hodges' model.

Here is some of the history of this geophysical feature:

"The buffalo jump was used for 5,500 years by the indigenous peoples of the plains to kill bison by driving them off the 11 metre (36 foot) high cliff. Before the late introduction of horses, the Blackfoot drove the bison from a grazing area in the Porcupine Hills about 3 kilometres (1.9 mi) west of the site to the "drive lanes", lined by hundreds of cairns, by dressing up as coyotes and wolves. These specialized "buffalo runners" were young men trained in animal behavior to guide the bison into the drive lanes. Then, at full gallop, the bison would fall from the weight of the herd pressing behind them, breaking their legs and rendering them immobile. The cliff itself is about 300 metres (1000 feet) long, and at its highest point drops 10 metres (33 ft) into the valley below. The site was in use at least 6,000 years ago, and the bone deposits are 12 metres (39 feet) deep. ... The importance of the site goes beyond just providing food and supplies. After a successful hunt, the wealth of food allowed the people to enjoy leisure time and pursue artistic and spiritual interests. This increased the cultural complexity of the society.

In Blackfoot, the name for the site is Estipah-skikikini-kots. According to legend, a young Blackfoot wanted to watch the bison plunge off the cliff from below, but was buried underneath the falling animals. He was later found dead under the pile of carcasses, where he had his head smashed in.^{"
