As some of you know I'm currently doing an evening class on the Geology of Scottish Hills. The tutor for this course also runs Geowalks, a company that offers geological walks around Edinburgh and other parts of Scotland. This morning Crafty Green Boyfriend and I joined a Geowalk along part of the Water of Leith and up the nearby Easter Craiglockart Hill. It was a very interesting walk, and the weather was perfect, a bit cloudy to start with, but becoming clear and almost warm later. We learned a fair bit about the sandstone rocks that underlie the Water of Leith and the igneous rocks in Easter Craiglockart Hill, which was a volcano millions of years ago during the Carboniferous period when what is now Scotland lay on the equator and was a very active volcanic area.
I recently posted this photo of some rocks in the Water of Leith and mansuetude asked whether they were slate. Well the answer is no, they're a kind of sandstone. It is interesting though that Slateford, which is a former mining village, now part of Edinburgh, along the Water of Leith, is so called because of the 'slate-like' stones by the river.
There will be another Geowalk along a different part of the Water of Leith in June, so I'll write a bit about that too!
