|These acidic soils are found on Palaeogene sediments around the foothills of the Otway Range but are often influenced by more recent|
The surface soil is a dark fine sandy loam over a brown occasionally bleached lower subsurface horizon, which grades into a weakly structured brown sandy clay loam and then into a yellow mottled clay at about 30 cm (variant: 100 cm) to about 90 cm or more. The sands with pans (Podosols) are usually reworked material which can be found on dissected slopes. The soils are deep and strongly acidic with a deep bleached sand/loamy sand subsurface horizon over a coherent pan (coffee rock) at 100 cm or greater. There are variable depths of dark surface soil (loamy sand) which tongue into the bleached material.
Notable characteristics include: gradational development of soil profile, fine sand component, medium to medium heavy textures (fine sandy clay loams to sandy clays), deep (>100 cm). Deep bleached sands over coffee rock characterise the sandy soils.
