Another lonely erratic here! Look directly East from the cache site to see it. This one may not look like much from the road, but we wandered over to it and it is still a VERY large chunk of rock. It might appear smaller because this particular erratic lies half-buried in the ground by the looks of it.
If you are not familiar with these peculiar Alberta rocks, then check out the links I have posted below. As a short summary, they are mountain chunks which fell onto giant ice sheets/glaciers thousands of years ago when Alberta was in its last ice age. The ice slowly moved over thousands of years, and took these quartzite boulders along for the ride. When Alberta began to warm up, the ice would melt and drop these boulders. Thousands of them, in fact. Some are the size of a house, like the world's largest glacial erratic, which is near Okotoks, Alberta. This one is nowhere near that size, but it is definitely a part of the same "Foothills Erratics Train" that deposited the Okotoks erratic. We love looking out for them as we drive through the Alberta countryside, and so we like to show other people these unique Alberta geological wonders!
