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 |
No water observed but soils are moist in patches after recent snowfall

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 but without a surface boulder cover and a salt horizon |
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 |
