Bracelet Bay and Mumbles


Tom has had another good walk out ......An enjoyable trip to Bracelet Bay and Mumbles point. 

Dunes and ripples at Bracelet Bay towards Mumbles' lighthouse. 
The majority of the beach is cobbles and bedrock. The grazing patterns from molluscs creates some interesting designs.

Just above the beaches of Limeslade and Bracelet Bay, where the sandy soil is exposed, there some fantastic aggregations of ivy bees. They formed great aggregations, which were very active in the midday sun.

In the limestone there is a lot of veining, predominantly calcite and haematite. Further west in Limeslade bay it was mined during the Roman era for iron production.

I was hoping to find some remaining autumn ladies tresses, but sadly the area had been mowed, there was, however, plenty of scarlet pimpernel and century sp.
