Sandy Bay/Middle Hope, North Somerset

23rd December: Spur and furrow morphology at Sandy Bay, North Somerset.



The spurs comprise silts and clay with some sand, the base of the furrows being lined by a coarse pebble/fine cobble layer, which could be an underlying sediment or a lag deposit dragged into the furrows by the tide.

Swallow Cliff Bay drift sequence. The most complete exposure is found in the south-eastern corner of the bay (right-side of image) where it rests on the fossil shore platform, here it is cut into [Carboniferous] basaltic lava at about 12.5 m OD.
