Norber Erratics

The view from Norber Erratics in the Yorkshire DalesA Bit About Britainโ€™s geomorphological expert will know that erratics are rocks that have been transported by a glacier, and left behind when the ice has melted some distance from where they started.ย  Itโ€™s a descriptive term, because โ€˜erraticโ€™ means โ€œuncertain in movement, irregular in conduct, habit, opinionโ€ (Oxford dictionary of English) and rock erratics can certainly look disorderly.ย  They are also known as โ€˜boulders in the wrong placeโ€™ and are frequently of a different rock type to the one they end up sitting on; so they can indicate former ice flow.ย  The Norber Erratics on the southern slopes of Ingleborough in Yorkshireโ€™s Dales country are a prime example.ย  They have a very distinctive appearance โ€“ and there are loads of them, all gathered together in one area.

Austwick, a dales village in North YorkshireThe old market cross in Austwick, North YorkshireThe Norber Erratics are (apparently) a hard form of sandstone known as โ€˜greywackeโ€™.ย  They date from the Silurian period and are about 430 million years old.ย  I hope that makes you feel better about yourself.ย  The rock underneath is carboniferous limestone, which is younger by around 100 million years, formed in a shallow, tropical, sea.ย  As Sherlock might have said, โ€œSedimentary, my dear Watson.โ€ย  Itโ€™s thought that the older sandstone boulders were ripped from the ground by massive ice sheets and deposited at the end of the last ice age, around 12,000 years ago. Some erratics of the Norber variety are perched on relatively narrow pedestals of limestone, because the base of the older and harder sandstone has protected the weaker limestone below from erosion.ย  Anyway, you can also tell the darker sandstone from the lighter coloured limestone, because the former is covered in green lichen and the latter in white.ย  Iโ€™m honest enough to admit that I hadn’t noticed that and didnโ€™t know about it until I read it.

Norber Erratics from Thwaite LaneThe landscape of Norber ErraticsPlace names fascinate me.ย  Iโ€™m intrigued by โ€˜Norberโ€™ and, assuming it didnโ€™t once belong to a landowner called Norbert (which I guess is possible), like to imagine a conversation between a local farmer and a visitor to the Dales long ago that went something like:

Ancient tourist: โ€œWhat are those rocks?โ€
Ancient farmer: โ€œWhy, t’aint nobbut erratics…โ€

A more likely, prosaic, option of โ€˜hill to the northโ€™ is offered by the Daelnet website, presumably derived from the Old English nord and the Anglian beorg or Old Norse berg.

They are all a-jumble, as though some giant has scoped up handfuls of large stones and scattered them, randomly across the landscape, in a dice-throwing move of the arm.ย  In good weather, itโ€™s a delight and a good place for a picnic. ย The walk to get there takes you through some lovely, verdant, Yorkshire Dales scenery and the views are great. ย In poor weather, I imagine it to be a bleak, unfriendly, place, where itโ€™s easy to miss your footing โ€“ or your way. ย Beyond the erratics lies a limestone landscape that needs to be explored another time (though it can form part of a slightly longer circular walk).

The easiest route is from the village of Austwick.ย  Starting from the old market cross (probably 15th century, pillar c1830s) in the centre of the village:

  1. Take the road to Horton, pass the Game Cock Inn and the school, and turn left up Townhead Lane.
  2. Pass Austwick Hall and take a footpath on the right by an old milk-churn stand.ย  The path goes through someoneโ€™s garden.ย  At the top, go straight ahead to a stone wall by a driveway and cross the stile into a field.
  3. Keep going up, then down by an old barn on your right, cross a track (Thwaite Lane), over the wall opposite into another field where a stream bubbles, up the hill to a ladder stile at the top.
  4. Cross the lane (Crummack Lane) and go over the stile more or less opposite.
  5. The path will take you by Nappa Scars (itโ€™s a bit of a drop, so watch your step) and at the end of a small rock face youโ€™ll see Norber Erratics on your right, behind a wall with steps over.ย  It looks as though the wallโ€™s trying to keep the rocks penned in.

Turn right and back to Clapham via the tunnels under Ingleborough Hall Estate to the church.ย  Turn left to return to the car park.

  1. It is very interesting to see these geological phenomena ‘in the flesh’, so to speak. I have seen one or two erratics on my travels but never so many in one place, as at Norber. I am adding yet another must-see place to the ever-growing list!

  2. I have visions of these erratics wandering home after a pub crawl…and not making it.
    Leo knew what they were though – remembering from his school days.
    Super post.

  3. “Geology rocks!” So do youi Mike – thanks for another stunning piece of wit laced imagery and information. I can just imagine a question on this subject for a jackpot round on Pointless. “Name the towns villages and pubs on the route to the Norber Rocks” I bet a lot will qualify as pointless!
    (For the benefit of your overseas fans I’d better add that, in this context, “Pointless” means “little known”, the aim of the quiz being to find an item on a list that 100 people have failed to spot, given a 100 seconds to do so.)

    I know many people adore Yorkshire and surrounding counties, but give me the south coast any time ๐Ÿ™‚

  5. Geology rocks indeed ๐Ÿ˜€
    A walk to Norber erratics sounds just like my kind of walk. Did you know that erratics in German are called “Findling”, as in foundling, something (or someone) that was found quite by coincidence?
    Also, we still use the terms Nord and Berg for north and hill, so “Nor(d)ber(g)” would be easily understood over here.

    Yep. You’ve got all the basic facts right if I remember correctly from a geography lesson some 50 years ago. And oddly I remembered a lot of that lesson and had to make a special pilgrimage to the Norber area when I stayed at Skipton back in 2004. Your photos reinforce memories of that day.

  7. Your blog posts are a terrific blend of scholarship and humor. I love your aside about boggy depressions as well as these sentences: “The Norber Erratics are (apparently) a hard form of sandstone known as โ€˜greywackeโ€™. They date from the Silurian period and are about 430 million years old. I hope that makes you feel better about yourself. The rock underneath is carboniferous limestone, which is younger by around 100 million years, formed in a shallow, tropical, sea. As Sherlock might have said, ‘Sedimentary, my dear Watson.'” We have had a lot of snow recently (more falling as I type) in the Boston area of New England. The photos in your blog post are a balm for my spirit. Thank you!!!
