The name itself offers a quiet clue: "esker" derives from the Irish eiscir, referring to a long ridge of gravel and sand deposited by meltwater streams beneath retreating glaciers at the end of the last Ice Age. These sinuous landforms were significant in early Ireland, used as natural routeways across boggy terrain, and settlements or enclosures positioned near them were rarely placed there by accident.

An enclosure, in the archaeological sense, is a broadly defined category: it typically describes an area bounded by an earthen bank, a ditch, a stone wall, or some combination of these, and it could date from anywhere between the Bronze Age and the early medieval period. In Ireland, many such features are the remains of a rath or ringfort, a circular enclosed farmstead once home to a family of some local standing, though others served as burial grounds, assembly places, or stock enclosures. Without excavation or detailed field survey, the precise character and date of the Eskerlevally example remains open. What survives above ground, how legible the boundaries are, and what relationship the site bears to the esker ridge nearby are details that remain, for now, unrecorded in any widely available source.
