How much do we know about Stonehenge? Less than we think. And what has Stonehenge got to do with the Ice Age? More than we might think. This blog is mostly devoted to the problems of where the Stonehenge bluestones came from, and how they got from their source areas to the monument. Now and then I will muse on related Stonehenge topics which have an Ice Age dimension...

Ice and fire
If you only look at this blog because you are interested in that old ruin called Stonehenge, look away now! If, however, you are a normal human being you cannot, I'm sure, fail to be impressed by how similar flowing volcanic lava (under certain conditions) is to flowing glacier ice (under certain conditions). Quite amazing. Some lavas and glaciers do admittedly flow in different ways, depending on viscosity and other factors. Some lava is cooler and more brittle, and some is almost as runny as water if it is flowing at a very high temperature. Some ice is also much more "brittle" and flow characteristics will depend on temperature regime, gradient, bed lubrication etc .....
There now, isn't that interesting?

and your point is???
No real point, Dave. Just celebrating the beauty of the natural world. Isn't that enough?
Come to think of it, I suppose I was intrigued by the thought that extremely hot and extremely cold flowing media follow the same physical laws. Which, I suppose, is as it should be.
I concur with Brian. Just as the patterns in nature such as a spiral galaxy, a hurricane photographed from space, and the Chambered Nautilus have very similar forms.
