| Weathering continues on the surfaces at higher altitude with alteration and oxidation to greater than 30cm depth; salt patches are common under many surface |
| stones; in places the soil has a very distinctive sulphur like colour; the yellow coloured soil patches seem to be associated with dark coloured rock |
