 Okay, so we've moved about 10 meters over it now, and we're looking down at some material here that I'd like to point out. Now this large piece of rock here, that is an erratic. That is a dropstone. Because this is something that could never get here by water. This material could only have been put here by a glacier, which became an iceberg, dropped this down, or somebody 290 million years ago brought a boat and carried it out and dropped it. Which is not very likely, considering we hadn't evolved yet. However, notice this is a metamorphic rock. It's not a sedimentary rock. It's a piece of material from the hinterland. The hinterland being up in the hills, higher elevation from here. Now if we look over here, this is a completely different rock with completely different shape. In fact, as we start looking around, we see that there are all kinds of little bits of material in here that have no business being here. So this is one piece of evidence that tells us that we were in a very cold climate.
