*Aust. Soil Class.:* Haplic, ?, Black CHROMOSOL (confidence level 3)

General Land Unit Description:
This land unit consists of undulating rises north of Vite Vite North. Shallow Black Chromosols with patches of shallow black self-mulching Vertosols occur on mid and upper slopes. There are many surface stones on these slopes and Red Chromosols and Dermosols occur in the vicinity of the eruption point. The soils of the lower slopes merge with those of the plain and are poorly drained Brown Ferric Chromosols or Grey Sodosols. All soil variants may be sodic at depth.

Site Description:

Geology: Quaternary basalt	Landform pattern: Undulating rises
Position in landscape: Mid slope	Internal drainage: Imperfectly drained
