Glacial Boulder - Cannock Chase
Glacial Boulder - Cannock Chase
Set upon a pedestal of Triassic pebbles, the boulder is of Granite which is out of place here on the Moorlands of South Staffordshire, there being no granite outcrops anywhere in the Midlands. The boulder has been matched however, to the intrusive rock outcrop at Cniffel in Dumfries & Galloway, which is over 170 miles (280km) away from the Chase in the Southern Uplands of Scotland. This granite 'erratic' is marked on the OS map as the "Glacial Boulder", which gives some idea how it got here. The boulder was ripped from its parent mountain sometime during the last Ice-Age, and was transported by glacial action to its present location, the journey perhaps taking ten-thousand years during which the edges of the rock were worn down, giving its present rounded appearance.
