Descr
At the southern end of Taylor Ridge, at the upper (eastern end) of a westward sloping terrain comprising a sequence of glacial retreat surfaces of differing age; |
an intermediate broad and flattish shoulder surface; this site is alongside site 274 and 275 and the salts were collected from beneath a range of surface rocks |
Geoland
The local rocks are medium to fine grained granite; thin patchy till overlies bedrock at higher altitude but the till cover is more continuous at lower altitude with |
several distinctive moraine loops; some dolerite, schist and other rock types are present |
Surfwea
Some cavernous weathering of boulders and exposed local rock outcrops; surface boulders generally well rounded with weathering through exfoliation; darker |
rocks fragmenting through thermal disaggregation; staining generally on upper sides of boulders only; salts beneath some surface boulders and boulders of |
differing rock types |
