A fascinating insight into the geology and topography around Loch Aline. The rock types include volcanic lavas, Jurassic shales and limestones, and white silica-rich sandstones. The sandstones were formed in shallow seas and represents a pure form of silica dioxide (SiO2) (silica). It has been extracted by the Lochaline Sand Mine since the Second World War. The board describes the industrial uses of the silica, as well as the workings of the mine.
Look out for fossils on the shoreline, such as Gryphaea ( Devil's toe nail), a genus of fossil oysters, extant around 200 million years ago. If you are lucky you may also come across some fossilised ammonites. There are some samples of these on the board. Please leave any fossil finds on the beach for others to enjoy.
The board is located just passed Lochaline Sand Mine on the Kinlochaline Low Road Walk.
An excellent, well sited board with good interpretation and much interest.
