Inland sand ridges, composed largely of unconsolidated sand, exhibit inverted relief landform. These inland sand ridges store groundwater in perched aquifers formed by layers of clay dominated geological material. Vegetation located on these inland sand ridges may depend on the sub-surface presence of perched groundwater to meet some or all of their water requirements.
