I was driving back down to the north east when I spotted a sing saying Ice Age Landscape. You know, one of those brown ones that indicates an item or area of interest. So I quickly turned off the road onto a narrow, single track road and followed it along a valley until I came to a viewpoint. After parking I read an info board which said that this was Glen Roy, and was virtually unchanged since being formed by glaciers during our last ice age.

You can clearly see the parallel lines going around the valley walls, where the different levels of water had been when it was a lake, and the scouring effect the ice had as it washed slowly along the ground carving out the glen itself.
I’m not a frustrated geologist, but I find all this stuff fascinating and spent an afternoon in Glenroy just marveling at the landscape and how it had been formed.
