Visible as long, parallel earthen ridges running across the landscape, these features are the remnants of a cultivation method known as lazy beds, a technique used widely across Ireland for growing potatoes and other crops, particularly from the seventeenth century onwards and into the post-Famine period. The ridges were formed by turning sods inward to create raised planting strips separated by drainage furrows, a practical response to wet, marginal ground of exactly the kind found across Connacht's interior. Where the land was later abandoned, these earthworks survived, preserved beneath the encroaching bog rather than ploughed flat by later agriculture.

Cultivation ridges of this kind are among the more quietly affecting traces left on the Irish landscape. They represent the labour of communities who farmed ground that would today be considered entirely unsuitable, often under considerable economic pressure. In upland areas like Keelogyboy, their survival is largely a consequence of that same marginal quality: the land was worked intensively when necessity demanded it, then left when circumstances changed, whether through emigration, consolidation of landholdings, or simple exhaustion of the soil. The ridges at Keelogyboy are recorded as an archaeological monument, placing them within a broader pattern of post-medieval agricultural survival across the west of Ireland, where the contours of former tillage remain legible across hillsides and blanket bog alike.
