Geology

Geological setting:

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

Patterned ground:

Nil

Surface weathering or surface features:

Surface boulders are angular with patchy surface staining but negligible staining on undersides; salts occur under stones and as thick discrete accumulations in the soil
