IT ALL COMES DOWN TO THE GUIDING
Meet your guide – here’s a great interview with award-winning geologist Ruth Siddall
Ever wanted to learn more about geology but don’t know where to start? Join me, Ruth, for this walk to find out more about geological materials through building stones – urban geology.
This walk will look at igneous, sedimentary and metamorphic rocks in the area around London’s Guildhall. We will also find a variety of fossils and learn about the geological environment and timescales in which the rocks now used to build the city of London formed.
IT ALL COMES DOWN TO THE GUIDING
Ruth Siddall is the real deal – she’s a top-flight, award-winning, professional geologist.

Full of information I never knew I needed. Fascinating and well-led by Ruth with passion and expertise. Opened my eyes to a new side of London – I shall be constantly pausing to inspect walls and paving now.
Conchita Navarro Sáez –
Ruth’s walk was so worthwhile. I’ll probably go again! She wears her experience and knowledge lightly, and led walk with humour, insights, fascinating facts….made very accessible to novices like myself. The pace was perfect, neither too fast nor too slow. My only wish is for a smaller group next time! Thank so much Ruth
Wendy Lomnes –
Hello Ruth;
I’m a Canadian geologist who would like to go a geology walk in mid April. Will you be leading them then?
David –
Ruth is brilliant. The walk (on a damp February afternoon) was brought to life by her infectious love of geology, rocks and fossils. Technical points are explained in simple terms and it brings new life to buildings we see every day.
Sue –
It takes a special person to encourage 16 adults on a cold Saturday afternoon in February, to get down on their haunches to observe a London paving slab, or to walk along imposing city buildings, caressing and observing the stone work. Ruth did just that! Her passion is infectious. Brilliant walk.
Joseph Cowan –
A wonderful, entertaining, fascinating walk. Ruth was marvellous.
