Soils within this unit are dominated by the Hazel and to a lesser extent by the Elioak and Glenelg soils. The Hazel soil series are moderately deep and well drained and are formed in the weathered products of metagreywacke sandstone and mica schist. Hazel soils lie on the uplands and their slopes range from 7- 45 %. The Elioak soil series are deep and well drained and are formed in the products of weathered micaeous metamorphic rock. Slopes of the Elioak range from 2 -25 %. The Glenelg soils are also deep and well drained and are formed in the weathered products of quartz mica schist. Slopes of the Glenelg range from 2 -45 %.
