Storm & sunlight over the Norber boulders & Moughton Scars
Following a storm, dramatic low sunlight illuminates the limestone of Moughton Scars near Austwick, North Yorkshire. In the foreground are glacial erratic boulders of greywacke ('Millstone Grit') of the Norber boulder field.
Dales sheep graze on the hillside amongst the rocks, with the lavender-hued hills of Moughton Scars beyond.
Glacial erratic boulders were transported sometimes great distances by a glacier during the last Ice Age and deposited on top of the very different local rock as the ice sheet started to melt. As such, they stand out as alien to the surrounding landscape and they serve as reminders of the sheer power of glaciers.
On Norber, much of the local limestone rock has been eroded away, but a little survives under the protection of the much harder greywacke boulders where it acts as a pedestal as seen here.
