Ellen’s Glen
Ellen’s Glen is a local nature reserve and offers peaceful wooded walks along Burdiehouse Burn in the south-eastern suburbs of Edinburgh. The underlying geology, often exposed in the Burn and the valley walls, shows near to vertical bedded sedimentary rocks that demonstrate the extreme forces involved with the development of the nearby major Pentland Fault. The sedimentary rocks belong to the Lower Limestone Formation and the upper West Lothian Oil-Shale Formation placing their age around 330 million years ago, a time of shallow seas, deltas and periodically inundated forested mires to which the Lothian Coal Seams owe their origins.
