On our latest whirlwind trip to Calgary, we stopped briefly just west of Okotoks to have a look at the "Big Rock". From the picture, it seems to be just a rock in a field. However, the rock holds an interesting tale.

The rock is officially known as the Okotoks Erratic. An erratic is a piece of rock that deviates from the size and type of rock native to the area in which it rests; the name "erratic" is based on the errant location of these boulders (definition from Wikipedia). The reason that these rocks get displaced is glacial movement.

The Okotoks Erratic is the world's largest known glacial erratic. It is believed to have once been a part of Mount Edith Cavell, located in Jasper National Park. Somewhere between 10,000 and 20,000 years ago, it made a 350KM trek atop a glacial ice sheet from its original location to its current resting spot near Okotoks.

As Paul Harvey would say... and now you know the REST of the story.
