I went hiking at Nose Hill Park this afternoon. The stone in the picture above is a large glacial erratic, about 10 feet tall, used by buffalo as a rubbing stone for many thousands of years.
Of course, I had to climb it...
On another stone, we noticed a carved symbol. There was no sign to explain it, and I was unable to find any information online, so I don't know if it is an old Indian petroglyph or something more recent.
Here is the same stone, its symbol visible behind Lorna.
It was cooler today, and quite overcast by the time we were ready to return home. As usual, there were few people in the park. The city plans to upgrade the trails and pathways in the near future. Right now, though there are trails, people wander wherever they like and I suppose they do some damage.
