County Carlow, Leinster, Ireland (52.69054 -6.82502)
The soils of the county are mostly derived from glacial till, rather than solid bedrock geology. These typically consist of a mix of clay, sand and gravel. Occasionally glacial melt-water would form a long ridge of sand and gravel known as an esker. One such example is preserved within the county and is a proposed natural heritage area, referred to as the Ballymoon Esker. The north of the county is generally flat, while central and southern Carlow are characterised by an undulating to rolling topography which becomes progressively hillier towards the south and east. The Blackstairs Mountains are the highest and most extensive upland area, with Mount Leinster rising to 794 m (2,605 ft), making it the highest point in both Carlow and Wexford and the seventh highest county top in Ireland.
