Rouken Glen Geology Walk

Friends of Rouken Glen Park  - a Geology visit led by John Faithfull on Wednesday 27^th April.  

Around 30 people turned up to have a walk round Rouken Glen and hear about the geology of the park.  John, in his usual enthusiastic style, explained the evidence of glaciation;  the presence of a section of fossilised Carboniferous tree, and the exposure of Giffnock sandstone.  He then led the group into the glen which is a SSSI. 

Here he explained the evidence of changes of environment using fossil evidence which can be found in the stream.  John handed around Lockeia (burrows), examples of marginal marine fossils from a location at the foot of the stairs and further into the glen at the site of the Orchard Beds he dredged up rocks containing crinoids and brachiopods.  He explained the importance and rarity of the short section of Orchard beds of the Upper Carboniferous which at the present are covered by landslip and foliage.  He and Al McGowan intend mapping this section in detail to determine the assemblage of each section of the beds.
