Kiltullagh Esker

Kiltullagh Esker is a glacial ridge in County Galway, Ireland. It is associated with Kiltullagh Lough and the lowlands around it.

An esker is a ridge of sand and gravel deposited by meltwater flowing through or beneath glacial ice. Kiltullagh Esker is therefore a remnant of Ireland's glacial landscape rather than a normal bedrock hill.

Kiltullagh Esker is notable partly because it sits in a landscape associated with Kiltullagh Lough. The ridge and the lough together illustrate how glacial deposits shaped the surrounding County Galway lowlands.

They preserve evidence of the movement and melting of ancient glaciers. Kiltullagh Esker is a named example in County Galway, where its sand-and-gravel ridge can be read alongside the nearby lough and lowlands.
