reading rocks
Geologist and writer Ian Jackson reads a selection of stories from his five books about northern rocks and their connections with the landscape and people. The first series, Time Travelling, begins almost 500 million years ago and ends with the Roman conquest of the north.
Episodes
Rocks, ripples and reformers
Send us Fan MailThere can’t be another short walk in the country where you can search out the fossil plants and animals from hundreds of millions of years ago including the oldest recorded amphibian footprints, walk across evidence of ancient earthquakes, touch rocks that were once 1200° molten magma and see the debris left by the last ice sheet to cover England, stroll past the site of a 10,000 y
Time-travelling by train Carlisle to Newcastle - part 3
Send us Fan MailThis the final part of this rail journey from close to the west coast of England to the east coast, starts in Hexham and finishes in Newcastle upon Tyne. On the way there's a little discussion about geological maps and their availability and accuracy. But mainly we'll be looking at the geology and landscape - the river deposits and the valley - the challenge such valley r
Time-travelling by train – Carlisle to Newcastle part 2
Send us Fan MailWe got as far as Brampton station last time. We have changed bedrock from the red Triassic sandstones of the west to 335 to 310 million year old Carboniferous strata – a repeating mix of layers of sandstone, shale, limestone and coal. A product of different past environments when the tectonic plate we were part of was on the Equator. Back then the land and sea kept changing places
Time-travelling by train - Carlisle to Newcastle - Part 1
Send us Fan MailOur journey starts in Carlisle and heads east. In a nutshell in terms of bedrock geology we begin on rock that is around 250 million years old from the Triassic period and as we head eastward travel over progressively older rocks crossing into 330 million year old Carboniferous strata around Brampton Station. Then we are on Carboniferous all the way to Newcastle – and once we get p
Kielder Rocks
Send us Fan MailWelcome to the most remote and wildest part of our region. It’s a place where the skies are darker and the stars shine brighter. Where ospreys feel safe enough to hunt and nest. Where red squirrels, goshawks and pine martens all feel at home and where other long disappeared species may soon be encouraged to make a comeback. Its Kielder’s landscape that makes that possible and it is
Time-travelling by train - Carlisle to Settle
Send us Fan MailThese podcasts originally started as abstracts from some of the 260 places in the 5 rock books. They are themed differently to the books – by geological time, the relevance of rocks and most recently Series 3 and 4 took journeys along Hadrian’s frontier and down the 4 big northern rivers. Along the way podcasts have been evolving and some other geology not in the books has been get
Wonderful Wear
Send us Fan MailI know the River Wear starts at the confluence of several streams at the eponymous Wearhead, but we are going a little way up one of thse streams to Killhope. We will pick up a tale of lead mining there - the geology related to the mineral wealth of the North Pennines will be the thread that joins a lot of the stories in first part this episode. Then after a little Whin Sill and s
The garden of Eden
Send us Fan MailA journey from source to sea but this time the Irish sea. The River Eden starts in the south and flows north before turning west near Carlisle and heading to the Solway estuary. There are quite a few places we’ve already visited along the river in previous podcasts so we’ll do a quick recap and you can always click on the earlier episodes if you’d like to know more.
There's only one Tyne
Send us Fan MailSince the last episode we and the river have flowed past Newbrough with its definite Roam road and indefinite Roman fort and go and on through Hexham. Both places described in previous episodes. The Tyne is now a single river. Waters meet was passed at Acomb. Hexham is worth a pause anyway. Its fine Abbey and medieval buildings – many made with robbed – sorry repurposed – Roman S
Seduced by Silver but sustained by lead
Send us Fan MailWe begin quite a way up the South Tyne Valley – appropriately at a place called Tynehead to try to get to the bottom of the many stories about the Romans and silver mining in the north. The metals theme continues with stops and stories at a prehistoric barrow at Kirkhaugh and a Roman fort thought by some but not all to be positioned to protect Roman state lead mining. The episode e
The Tees - from the moors to the coast
Send us Fan MailThis is a journey from moors above the middle reaches of the River Tees near Barnard Castle to its mouth where it empties into Hartlepool Bay. Along the way the plan is to look at some prehistoric rock art at Barningham, celebrate the merits of sand and gravel and a hear a cautionary tale about flood risk, revisit the salt deposits of Teesside and in Hartlepool Bay hear about some
A trip down the Tees
Send us Fan MailThe first of our journeys is along the River Tees. The Tees has its headwaters way up in the Pennines, in the Carboniferous rocks just east of Cross Fell, but downstream of Cow Green Reservoir it cuts through some of the oldest rocks in Northern England – that’s why its the first or the rivers in this series. On our way downstream we will explore some different bits of the Whin Sil
The far east
Send us Fan MailThe episode title of this section of the Roman Rock Trail isn’t perfect – as we are starting in west Durham in a place called Lanchester, then returning to the Wall at Heddon – a village which owes its position to its hard sandstone bedrock resisting glacial erosion more than the surrounding area. And then onto Benwell. A place not on the current Hadrian’s Wall Trail but from what
Scratching the surface
Send us Fan MailThis episode initially takes us from Chesters on the Wall to Hexham. South of the Wall but very much a gateway and one with some important recycled Roman rocks. Then back to close to the Wall at Fallowfield before jumping back south to Roman Corbridge – Coria or sometimes Corstopitum. The geology will be as diverse as the geography. From the rocks that made millstones to a cavalrym
Hard rock and hard water
Send us Fan MailAll of these podcasts are geological but this episode is three-quarters pure rock. First the plan is to look closely at the rock that provided the mortar for the wall – limestone – did the Romans use it to sweeten these northern soils too – they can be pretty acid. Next its more whin Sill – I am starting to wonder if there’s too much on this rock already, but it does play a huge ro
Channels and minerals
Send us Fan MailTime to descend into and out of one of the classic components of this frontier landscape - one of the "gaps". You have already experienced a few and today there will be a few more. But your legs need a break so we are going to deviate south of the Wall too. To see a ditch, then go find about two mineral resources that were used extensively by the Romans - coal and iron -
Forts, castles and camps
Send us Fan MailWe are starting at Bewcastle Fort around 10 kilometres north of Hadrians Wall – well that’s as the crow flies. But then we will be returning the Wall and some of its most dramatic landscapes and archaeology. From a ruined medieval Thirlwall Castle near Greenhead village – built completely of re-purposed Roman stones – we climb up onto the escarpment of the Whin Sill – 295 million y
Some Wall at last
Send us Fan MailOur journey east continues, we are about one and a half kilometres north east of Lanercost just over the line dividing the red St Bees Sandstone bedrock from grey brown Carboniferous rocks – although there is no bedrock to see here – its covered by a variable thickness of glacial deposits. Those thick stony clays sand and gravels may well explain why the first incarnation of Hadria
The western front
Send us Fan MailSeries 3 is an extended Hadrian’s Wall rock trail with little side trips and the first episode will start just north of a little seaside town called Maryport on the southern coast of the Solway Firth and head north and then east. We will take in salt making, how the Romans defended an estuary at Burgh Marsh, a large Roman building in Carlisle whose drains have produced a fantastic
The bedrock of our heritage
Send us Fan MailWe are so lucky in the north – apart from having far more open space than most people those open spaces have some of the most spectacular landscapes in Britain. Our northern landscapes are a result of our geology and their biodiversity and cultural heritage are profoundly influenced by our geodiversity. How to choose just 7 places to illustrate this? Someone will rightly ask – how
The ground rules
Send us Fan MailThe episode title does have a double meaning – the rocks and deposits that lie beneath us have a very strong controlling influence on what we do to our planet and what we don’t do and what we shouldn’t. They may take time to assert that influence but the fact is that ultimately nature will always win any fight we pick with it. I’m going to be talking about the experiences we humans
Rocks to riches Part two
Send us Fan MailThere are so many places across the north of England that show us how the human race has depended on rocks that I felt this topic needed at least 2 episodes. The last episode explored the origins of stone axes, copper, iron and lead ores, coal and graphite. This one visits 6 more places that have examples of very different uses for the geological resources of our planet. First we
Rocks to riches
Send us Fan MailIt is difficult to overstate how dependent we humans are on the resources geology – rocks – provide. It was rock that first provided prehistoric people with shelter and with the raw materials for their tools and weapons, jewellery and pots. Stones built their monuments and the tombs for their dead. Making fire is one of the things that distinguished us humans from animals – we stru
Lives in stone
Send us Fan MailThis second episode explores those northern rocks that are the domain of palaeontologists – rocks that contain fossils. These remains of lives long ago from sea shells to dinosaurs are one of the three aspects of geology that - along with earthquakes and volcanoes - excite the general public more than any others. How many geologists were seduced into the science by their fascinatio
A restless north
Send us Fan MailThis first episode of Series two - called a restless north - takes a look at how dynamic our land has been (and still is!). At least once or twice a year we are reminded of the awesome but terrifying power of the planet by catastrophic earthquakes occurring around the globe. Earthquakes happen here too – but on a more subdued level. But we have evidence in the north that they were
THE BLACK THREAD – Part Two
Send us Fan MailPart two of this short geo-fiction story looks forward 40 years and 100,000 years. It may be a speculative look into our future but it draws nonetheless on forensic climate projections and impacts which have been generated by reputable scientists. Reading the story of the Earth through its rocks has been likened to reading a book with 90% of its pages missing. An incredible tale an
THE BLACK THREAD a bit of geo-fiction for a change – Part One
Send us Fan MailReading the story of the Earth through its rocks has been likened to reading a book with 90% of its pages missing. An incredible tale and fertile ground for the imagination for sure. But everything in this two-part short story is based on sound scientific, archaeological and historical evidence. Part Two - the final two chapters of the story - may be a speculative look into our fut
The return of humans
Send us Fan MailIts time to get to grips with how people and rocks connect. And first in ancient societies. So we will be occupying the overlap – more no-mans-land – between geology and archaeology. The two subjects - just like rocks and humans - are inextricably linked. Our ancient ancestors relationship with their natural landscape – that is its rocks – was intimate. Rocks and sediments provide
Freeze and thaw
Send us Fan MailOur tectonic plates continued their erratic waltz north. All the while billions of tonnes of sediments were deposited, turned to rock, tilted up here and there and then eroded away. 60 million years ago lava started to pour out of an enormous rift that was to become the Atlantic Ocean. North America and Europe have been drifting apart ever since. 2.6 million years ago the Earth‘s
Red Deserts, salty seas, and an intruder
Send us Fan MailThis episode starts with injection of molten rock across northern England a rock that is responsible for a huge chunk of our tourist economy. Then it takes a tour of hot deserts, evaporating salty seas, and finally our secret bit of every fossil hunters dream rock. On the way we’ll hear about plots to blow up a famous stone circle, dispose of nuclear waste, a mass global extinctio
Totally Tropical
Send us Fan MailA virtual tour of six rocky places across the north of England that help us understand exactly what the environment was like around 330 million years ago in the Carboniferous period. The land we now call Britain wasn't 55 degrees north then, we were close to the Equator and our landscape alternated between steamy swamps, coastal lagoons, huge lazy rivers, and even coral seas.
Deep Time
Send us Fan MailThis is the first episode of the first season of these podcasts. They are based on my five books about northern rocks and their connections with our landscape ….and us. The stories of this first season – Time travelling - begin almost 500 million years ago and end with the Roman conquest of the north. Episode one begins deep in a southern ocean ....and on a hill in the Lake Distric
