I was thinking about how many of "fathers" of geology were scottish, James Hutton and Charles Lyell for example. However there are not tartans for their families, that I am aware of. I was wondering if there is an appropriate tartan to celebrate the influence of scottish geologists. I have seen pics of the "Highland Granite" tartan (Barb has shown a few pics) but I am wondering if there others that would be appropriate.
