Dark, lichen-covered rocks towered above us in near-vertical cliff faces, some overlain by frozen waterfalls.

Here, the upper mudstone of the TST is erosively overlain by 3 m of bioturbated, clayey sandstone and mudstone.
The exposed serpentinite dome was surrounded and partly overlain by crustal blocks.
However, the former clearly extends further to the east to overlie other parts of the faulted sequence and may also extend slightly further to the west than the underlying block.
soft clays overlie the basalt
A thin marine clay ironstone with a patchy distribution overlies the flint.
