Runcorn is perched at the northerly end of an outcrop of sandstone which overlooks the River Mersey, a reminder that deserts covered this area 250 million years ago. A series of red sandstone quarries dating back to 1734 litter the hill. This one was known as "Frog's mouth" and is popular with climbers. Extraction from this quarry ceased around 1850 and it was then gradually filled with the spoil of the newer quarries. The present level of the ground is about one third of the depth when it was a working quarry.
