Dave Green - Geology and Landscape
When
Tue, 28 May, 19:00 – 21:00
Description
Geology and Landscape of Gloucestershire and surroundings 
A weekly field-based introductory course. 
No previous knowledge of geology is assumed Tuesday evenings 28thMay to 16th July 2019 
Gloucestershire is one of the most geologically diverse counties in Britain. 
The aim of this field-based course is to take you towards an 
understanding of local scenery.  We will look at the components 
- the highly diverse  rocks and their structure; and processes 
- weathering, slope forming and erosion - which have combined to produce this equally varied landscape - the materials from 
which the scenery has been sculpted and the processes that have acted upon them since the area emerged from the sea 65 million years ago 
(about the same time that the dinosaurs became extinct) 
No special equipment is necessary, apart from stout footwear and possibly waterproofs - although we will hopefully have six balmy 
summer evenings! Meetings are held on Tuesdays each week, 
(apart from breaks on Tuesday 4th and 11th June), meeting at 7.00 pm and finishing 
at 9.00 pm or later (whenever the party feels in need of refreshment !!) at the following meeting points (see over) 
Cost: £50 for 6 week course 
or £10 per session 
For further details see over or telephone

28th May - Stinchcombe Hill

The most westerly point on the Cotswold escarpment, and possibly the most visible and easily recognised. The escarpment is formed from flat lying sedimentary rocks starting at the top with the often fossil-rich Middle Jurassic limestones (approx 170 million years old), which overlie weaker sands and mudstones forming the middle slopes. The harder Marlstone forms the famous platform on which the towns of Dursley and Wotton are built, underlain by more mudstones forming the Severn Vale, producing a step-like landscape. 
Meet at the car park on the left, beyond the entrance to the golf course GR SO 744 983

Mike Benton Lecture

Festival of Nature - Mike Benton Lecture

The Natural History Consortium has contacted me to inform me - and you - that Mike Benton will be giving a lecture at 6:30 on Thursday 6th June at The Station, Silver Street, Bristol, BS1 2AG. Book HERE

Details of the Lecture are:-

Festival of Nature 2019 includes a special series on nature writing. We’ve asked 5 different writers to join us at 4 feature events in Bristol to share their work, their upcoming projects, and to help us explore the nation’s ongoing love for nature writing. Join us!



We are living in ‘a new golden age of dinosaur science’ (The Times, 19 January 2019). It’s true. Recently, there has been a revolution in dinosaur science. Questions we thought we unanswerable can now be answered. How fast could dinosaurs run? What was the force of their bite? Were they feathered, and what colour were they? How did they care for their young? How could they be so huge?

Over the past twenty years, the study of dinosaurs has changed from natural history to a true scientific discipline. New technologies have revealed secrets locked in the prehistoric bones in ways that nobody predicted. Remarkable new fossil finds, such as giant sauropod dinosaur skeletons from Patagonia, dinosaurs with feathers from China, and even a tiny dinosaur tail in Burmese amber – complete down to every detail of its filament-like feathers, skin, bones, and mummified tail muscles – have caused media sensations. New fossils are the lifeblood of modern palaeobiology, of course, but it is the advances in technologies and methods that have driven the revolution in the scope and confidence of the field.

The Dinosaurs Rediscovered presents all the latest palaeontological evidence, with first-hand insights from behindthe scenes of the expeditions and in museum laboratories, tracing the transformation of dinosaur study from its roots in antiquated natural history to a highly technical, computational and indisputable scientific field today. In this engaging, anecdotal account, University of Bristol Professor Michael Benton explores what we know of the world of the dinosaurs, how dinosaur remains are found and excavated, and especially how palaeontologists read the details of the life of the dinosaurs from their fossils – their colours, their growth, feeding and locomotion, how the grew from egg to adult, how they sensed the world, and even whether we will ever be able to bring them back to life.

---------------------------------------------
NOTE BREAK OF TWO WEEKS HERE – no meetings on 4th and 11th June 

------------------------------------------

18th June Sandhurst and Wainlode 
The River Severn has eroded its course maily along the outcrop of the soft Triassic Mercia Mudstone or the Jurassic Lower Lias Clay. In between these formations is a thin series of beds of more resistant rock – the Rhaetic, which forms a series of low wooded ridges broken by faults, and occasionally cut into by the river (as at Aust, Sedbury, Westbury and here at Wainlode) to form impressive cliffs. This location is also a classic area to observe the Severn Terraces. Meet initially at the car park (along the lane) of the pub The Red Lion, at the foot of Wainlode Hill (SO848259), from where we will travel in a few cars to Sandhurst for a linear walk of about 3km with a climb of about 60m.

-------------------------------------------

25th June Bixslade and Bixhead 
Bixslade is a steep valley cut into the steep dip slope of the Upper Carboniferous Pennant Sandstone to the west of Cannop Pond> For hundreds of years used as a building stone, there used to be a tramway down from the main quarry at Bixhead to the stone cutting works at Cannop; a tramway that was also used to transport coal, and iron ore from deposits within the Pennant, that were worked within Bixslade. We will traverse the route of the tramway and return on a circular route involving a walk of about 3-4km and a climb and descent of about 130m. 
Meet in the layby (old section of road), on B 4234 north of Parkend, near the Stone Cutting Works, Cannop, at SO 615 095 

---------------------------------

2nd  July Glasshouse 
A complex area of geology, where relatively ancient Silurian, Devonian and Carboniferous rocks meet younger Triassic sediments along the Malvern fault system. The older rocks have been thrown into a series of folds, whose north-south trend is faithfully reflected in the landscape by the outcrop of relatively resistant and weak rock, forming ridges and valleys They have also been cut by a major fault (the Glasshouse Fault), bringing older rocks (Lower Silurian) in the core of the May Hill anticline next to them, with consequent effect on the scenery.  This fault is an example of a strike slip fault, with mainly horizontal movement taking place; a little similar to the present San Andreas Fault in California. Meet at the roadside downhill from the Glasshouse Inn (used as the car park for the pub) SO709214. We will look at the geology by means of a circular walk of about 
3km with a climb of about 40m. 

--------------------------------------

9th July The Avon Gorge 
Possibly the most famous landscape in our area, but one whose origin is still the subject of hot debate! Why does the River Avon cut through the hard Carboniferous and Upper Old Red Sandstone ridge forming hills like Clifton Down, and the steep sides of the gorge, when it could easily have reached the Severn either to the north (via Bradley Stoke) or south (via Nailsea) of Bristol? Why are the Downs so flat? 
Meet at the car park in the old quarry on the eastern (away from river) side of the A4 Portway below Clifton Down. ST 561 740, from where we will ascend a footpath “The Gully” to Durdham Down to gain a view and walk along towards the suspension bridge before returning to the car park

-----------------------------------------

16th July : Kempley and the Mystery Valley(s) 
The southernmost extremity of the Woolhope Dome lies just SW of the village of Kempley. The folded and heavily faulted marine Silurian rocks here form distinctive scenery in themselves, but the landscape is dissected by deep, steep-sided valleys, discordant to the underlying geology, some of them lacking any sign of the stream that must have eroded them. We will examine the geology and scenery of this beautiful area by means of a circular walk of between 4 and 5 km, along footpaths (some stiles involved) and quiet country roads over relatively gently undulating countryside. 
Meet at the large lay-by (SO672 295),  200 metres south of Kempley Church.

Support charities painlessly

Use Amazon to Support Your Favourite Charity - Especially North West Highlands Geopark

I was recently in the Scotland, in the Ullapool area, enjoying an excursion arranged by WEGA and run by the North West Highlands Geopark. And very good it was!

Suilven
The Geopark now has no government funding and needs to be self supporting. There are many ways you can help but an easy one is to use Amazon.

Assuming you have an account at Amazon go to smile.amazon.co.uk sign in, click on Account and Lists at the top right and, under Your Account, click on Your Amazon Smile and you can choose a charity. For the Geopark you will need to do a search but searching for North West Highlands Geopark will bring up only one choice. 

Next time you buy something from Amazon (make sure you go to smile.amazon.co.uk) about 0.5% of your purchase price goes to the Geopark. The price you pay is the same as normal, so you do not lose and the Geopark wins!

As of February 2019 they have received £44.39 - fourpence of which is mine!
