Soils

This soil occurs in the lower parts of the landscape and in areas adjoining the western and northern parts of the former swamp. It was first described by Holmes et al. (1940) and is essentially similar to the "Swamp Fringe Type" described by Goudie (1942).

Most of the soils are dark brownish grey to dark greyish brown clay loams to sandy clay loams overlying, at about 250 mm, brownish grey to greyish brown with rusty brown mottled sandy clay loams to light clays. This layer is generally, but not always, bleached. Mottled grey and brown medium to heavy clays occur from about 400 mm and extend to at least 1.8 m. The depth to the clay may vary from 200 mm to 500 mm. On the higher parts of the landscape adjoining the drainage lines the soil profile may be sandier. Soil Pit Site GP27 is an example of a sandier soil profile within the Narre clay loam mapping unit.

It should be noted that small areas of Toomuc sandy loam may also occur within this mapping unit.
