Classification:	Northcote (1979) – Dy3.41 Stace et al (1972) – Yellow Podzolic soil	A2	15-60 cm	Light yellowish brown (10YR 6/4) silty loam; abundant distinct brownish yellow (5-15 mm) and grey mottles; apedal; earthy fabric; hard when dry; pH 4.5; clear boundary
Location:	Moe 8121, grid ref. 309907 18 km N of Moe	B1	60-75 cm	Yellowish brown (10YR 5/4) silty clay loam; distinct dark yellow brown (5-15 mm)and common distinct grey (<5 mm) mottles; moderate medium (15 mm) subangular blocky structure; rough-ped fabric; firm when moist; pH 5.0; clear boundary
Land system, component:	Stewart, 1	B2	75-80 cm	Dark brown to brown (10YR 4/3) silty clay; abundant distinct yellowish brown and few distinct dark grey (5-15 mm) mottles; strong coarse (25 mm) angular blocky structure; smooth-ped fabric; firm when moist; pH 5.0; clear boundary
Topography:	Crest slope of hill, S aspect, 7% gradient	C1	85-120 cm	Brownish yellow (10YR 6/8) silty clay; abundant distinct white (>15 mm) mottles; structure uncertain; firm when moist; pH 5.0
Elevation:	240 m	C2	120-140+ cm	Yellowish red (5YR 4/6) light clay; abundant distinct yellowish red and few prominent yellowish brown (5-15 mm) mottles; structure uncertain; slightly firm when moist
Drainage:	Poor
Parent material:	Devonian and Tertiary siltstone and mudstone
Vegetation:	Woodland I: Eucalyptus consideniana with Leptospermum juniperinum, Epacris impressa, Pultenaea sp. and Gahnia radula common in the understorey
Remarks:	Soil appears to be very silty, scattered mounds of clay dug up by land crabs may be indicative of poor drainage
