I I I DESCRIPTION: Gravelly Lower Wash (1-5%) Slopes with lronwood and sparse Mulga over sparse annual and perennial grasses. I I I I I I I I I I I I I I I I I I GEOLOGY: LANDFORM: SOIL: 0.00 - 0.10 0.10-0.40 Quaternary colluvial gravels. Generally eroded wash material from higher relief Mountains and Rises. The gently inclined slopes of this landform generally have slopes to 5% with a relief to 10m above the surrounding lower lying areas. Clay forms about 20-30% of the soil fraction that would allow rapid runoff with moderate drainage and permeability. Where the surface structure has been disturbed, erosional channelling has resulted. Numerous small (0.5m wide x 0.1 Om deep) incised channels drain portions of the slopes and terminate in small alluvial fans. Example from Site 142 MGA.
