Landscape of the Norber Silurian Sandstone Erratics, glacial erratic boulders & limestone boulders. Austwick, North Yorkshire Dales National Park, UK
The Norber Erratics are glacially-transported sandstone boulders found near Austwick in North Yorkshire. They were eroded from cliffs 1km away to the north in Crummackdale and were deposited at Norber on Carboniferous limestones when the ice melted about 15000 years ago. Some of the larger erratics have protected the limestone beneath them while the surrounding surface has slowly been dissolved away by acid soil-water. These erratics now rest on upstanding blocks of limestone, known as pedestals, some of which reach 60cm in height.
