Geology of Edinburgh course: Carboniferous sedimentary rocks along the River North Esk, Roslin
This short circular walk in Roslin Glen, Midlothian explores a thick sequence of sandstone and other sedimentary rocks deposited in the middle part of the Carboniferous period.
THE ROCKS: There are sedimentary rocks from the Carboniferous period across central Scotland. Around 330 million years ago, a thick sequence of sandstone, the Passage Formation, accumulated. Recent erosion has created a spectacular gorge through the sandstone, and nearby there is a fantastic natural cross section through a varied sequence of slightly older rocks.
THE WALK: This circular walk will take us from Rosslyn Chapel through Roslin Glen, following the River North Esk upstream to the old gunpowder works. I have classified this as a Moderate Walk, not always on paths, it may be rough or slippery underfoot at times. It may be wet, windy or cold. Come equipped with strong footwear and waterproof clothing. Duration 3 hours, distance 5 km.
