Under Pressure
This is the Idol Rock, a classic balanced stone located in the Nidderdale “Area of Outstanding National Beauty” in Yorkshire, UK.
The rock is made of layers of the “Millstone grit”, a set of carboniferous-aged sedimentary rocks found throughout Northern England and Wales. These abrasive sedimentary rocks got their name by being commonly sampled as flat slabs that were used to grind and mill grains in early water-powered mills.
A single thin layer holds up the huge weight of this rock – you can see how the alternating beds have different levels of resistance to erosion as you look up and down the unit. A variety of other shapes in this area have their own nicknames - Sphinx, The Watchdog, The Camel, The Turtle, and The Dancing Bear, all reflecting different shapes left behind by erosion. One thing to remember about rocks – they’re really strong in compression. You can squeeze rocks a lot and they just push right back. Rocks are much weaker in tension – pull on rocks from both sides and they’re much more likely to break.

The two titled I picked up were “The Unofficial Countryside” by Richard Mabey and “Millstone Grit” by Glyn Hughes; and typically for me, having drafted my end of November post…

Laddow Rocks
Laddow Rocks, on the Pennine Way
Ewan MacColl, in his Manchester Rambler, famously sang that he had slept upon Crowden. But Crowden seems to be the name of the hamlet at the foot of Crowden Brook. I can’t find a moor or hill named Crowden. Perhaps he meant Laddow Rocks, a range of gritstone crags overlooking Crowden Great Brook. When MacColl wrote his song the crags were a very popular climbing venue conveniently accessed by…
