description Cloghchurnel Esker and Fan Overview

Cloghchurnel Esker and Fan is a notable glaciofluvial landform located in County Longford, Ireland. It consists of a long, sinuous ridge of sand and gravel known as an esker, combined with a fan-shaped deposit of sediment formed by late-glacial meltwater streams. This geological feature was created during the Quaternary period when retreating ice sheets left behind significant deposits. The site is recognized for its geoheritage value, providing visible evidence of Ireland's glacial history and the dynamics of subglacial river systems.

help Cloghchurnel Esker and Fan FAQ

What is an esker and fan landform?

An esker is a long, sinuous ridge of sand and gravel deposited by meltwater flowing through a tunnel beneath or within a glacier. A sediment fan forms where that meltwater emerged from the ice, spreading sediment outward in a fan-shaped deposit.

Where is the Cloghchurnel Esker and Fan located?

The Cloghchurnel Esker and Fan is located in Ireland, where glaciofluvial landforms from the last deglaciation are well preserved. Ireland's midlands are particularly rich in eskers formed by retreating ice sheets at the end of the last glacial period.

How old is the Cloghchurnel Esker and Fan?

The landform dates to the late-glacial period, when melting ice sheets deposited vast quantities of sediment through subglacial and ice-margin meltwater channels. In Ireland, this deglaciation occurred roughly between 15,000 and 12,000 years ago.

Can you visit the Cloghchurnel Esker and Fan?

Irish eskers are visible landscape features, and some are accessible via walking routes or roadways that follow the natural ridge lines. The Cloghchurnel site can be identified on geological maps of Ireland's glaciofluvial features maintained by the Geological Survey of Ireland.
