Australian Soil Classification: Vertic (& Sodic), Hypercalcic, Black DERMOSOL
General Landscape Description: Undulating rises.
Site Description: Upper slope adjacent to open depression.
NOTE: This profile was described as part of a catena transecting a small open depression in the basalt which has intersected the underlay sedimentary (Moorabool Viaduct) material.
