Esker Riada Esker Riada, ((アイルランド語:Eiscir Riada)), is a system of ridges that stretch across the middle of Ireland, between Dublin and Galway. ==Geography==
The Esker Riada is a collection of eskers, that passes through the counties of Dublin, Meath, Kildare, Westmeath, Offaly, Roscommon and Galway. A large remnant of the Esker exists in the Teernacreeve region of Westmeath, and stretches from Kilbeggan to Tyrrellspass. The eskers take the form of relatively low-lying ridges composed of sand, gravel and boulders; deposited by water flowing beneath a glacier; that became exposed when the glacier melted at the end of the last ice age, around 10,000 years ago.
