...the Newton shore where we chose to stop for second breakfast near the site of a considerable nonconformity.
Just below the wreck of this old boat (which has seen better days) lies an interesting geological feature,.It attracted the interest of the 18th century Scottish geologist James Hutton. He observed dipping old metamorphic rocks which were immediately overlain by gently sloping layers of much younger sedimentary rocks. There was no evidence of any intermediary rocks between the layers despite them being separated by 160 million years. Hutton used this unconformity to deduce that the underlying metamorphic rock had been created, metamorphosed, (altered by great forces) then uplifted and eroded before the later sedimentary rocks were overlain. Lastly, the two layers were then further uplifted then eroded to expose their junction on what is now Newton shore. He deduced from all this that the World was much older than had been previously thought.
Generations of geology students have followed Hutton to swarm all over his unconformity.
Leaving the unnconformity we passed the Fairy Glen on our way north.
This rock pippit was hopping between great...
...priapic boulders of conglomerate...
... which lay on the old red sandstone of the Cock of Arran.
