That combination, recorded but unexplained, is more common than it might seem across the Irish midlands and west, where the sheer density of earthen remains means that many have been noted and mapped without yet receiving the fuller attention that would tell us what they actually were.

Earthworks is a broad category, and deliberately so. It can encompass the raised raths and ring-forts that served as enclosed farmsteads during the early medieval period, the banks and ditches of field systems long since abandoned, the platforms of vanished houses, or the eroded remnants of enclosures whose original purpose is no longer legible from the surface alone. Moyne as a place-name derives from the Irish "muine", generally taken to mean a shrubbery or brake, a thicket of low dense vegetation, which gives some sense of how such townlands might once have looked before centuries of agricultural clearance. Whether the earthwork here belongs to the early medieval period that produced so many of Connacht's surviving field monuments, or to some earlier or later phase of activity, remains an open question.
