help Blakeney Esker FAQ
What is Blakeney Esker?
It is a well-preserved esker, meaning a winding ridge of sand and gravel formed by meltwater beneath glacial ice. The site is a geological landform rather than a normal coastal dune.
Where is Blakeney Esker located?
Blakeney Esker is near the village of Blakeney on the North Norfolk coast of England. Its coastal setting can make it look like an ordinary ridge even though it was formed by glacial processes.
When was Blakeney Esker formed?
The esker formed during the Pleistocene Ice Age. Meltwater flowing beneath the ice deposited the sand and gravel that later remained as the ridge.
How is an esker different from a moraine?
An esker is built mainly from sediment carried and sorted by meltwater in a subglacial tunnel. A moraine is usually an accumulation of glacial debris pushed or left by moving ice, so Blakeney Esker has a different origin.
