fresh air, sunshine and curiosity

Crisp, calm mornings are beautiful, they provide a perfect opportunity to get outside and up close with my local coastal geology. I return here again and again, there is always something new to discover and space to ponder the vast timescales on display all around.

In this picture I’m once more drawing amongst a raised Patella Beach, next to a wave-cut platform. Both of these date from the Eemian period 120,000 years ago and sit some 5m above the current sea level.

Drawing at Rhossili, sitting above a 125,000 year old limpet shell….

Embedded within a remnant of the ‘Patella’ beach to which it lends its name, the shell is held fast by ‘natural cement’ (precipitated limestone / calcium carbonate). This raised beach fragment is a relic from earth’s last warm period (interglacial) when the sea level was much higher than today - but temperatures were almost the same. A probable indicator of what is to come, perhaps in the next few hundred years, should global CO2 levels not fall below current levels.
