Number 8 in our Erratic Behaviour series. We have caches placed all over Alberta marking the locations of some of the smaller, lesser known glacial erratics, and this is another one. Of course, the Big Rock across the street gets all the attention, but perhaps you've driven past this little sister of the more famous Okotoks Erratic and never noticed it!
This is indeed another glacial erratic, just like the Big Rock. Whether it was originally a piece of the larger house-sized chunk across the highway, or perhaps just another lonely quartzite boulder along for a ride on the same glacier/ice sheet thousands of years ago, is unclear. What is certain is that this is another glacial erratic and part of the Foothills Erratics Train: one of thousands of such boulders strewn across the Alberta landscape--an ancient geological record of the last Alberta Ice Age. You can read all about them at the famous Big Rock across the highway, or visit the links below!
