A long weekend spent at Thurlestone, Devon for a family event – a cheerful one – meant time to explore an unfamiliar area. And the rocks on the beach were quite unlike any we had seen before; certainly unlike anything on our part of the Dorset coast, 100 miles or so to the west. So I took some photos. Having no geological knowledge, I can’t say if this is part of the real – or even the flexibly tourist office-defined – “Jurassic Coast”, but I suspect not. Here are some of the strange bumpy many-hued formations.

PORTLAND BILL, DORSET – ROCKS & FOSSILS 1
Pulpit Rock is an artificial stack of rocks at the southern tip of Portland. It was created in the 1870s during quarrying as a relic of the industry. It is climbable and is apparently somewhere that the adventurous like to ‘Tombstone’, an activity beyond my imagining.
The flaggy flat areas near the rock are reminiscent of the ‘Flaggy Shore’ of the Burren, Co. Clare
Rock. And a pretty wheatear. There were also meadow pipits, and lots of gullsÂ
The rock surfaces all round Pulpit Rock is known as ‘Snail Shore’, embedded with millions of snail, oyster and mollusc shells from what was once the seabed in Jurassic times. Here are a few examples, some surpassingly large.

PORTLAND, DORSET (2): CHESIL BEACH & THE FLEET
The Chesil Beach, or Chesil Bank, is a dramatic 18-mile curve of steeply banked shingle stretching north-west from Portland (the southern-most point of Dorset) to West Bay via Abbotsbury. The formation contains a long tidal lagoon known as the Fleet.*Â
Before a causeway road was constructed, the bank connected the mainland to the Isle of Portland, creating a form of TOMBOLO (strictly, it is a ‘barrier beach’). The uninterrupted shingle strip of Chesil beach is up to 50 feet high in places. The stones are large at the Portland end, gradually reducing in size until, by the western end at West Bay, they are pea-sized. It is said that in the past (and maybe still) local people were able to tell the location on the beach that a particular pebble had come from. This knowledge was supposedly helpful for the accurate landing of contraband at dead of night, smuggling being a popular occupation along the Dorset coast (and maybe still).

We sat on a tide-shelf above the waterline – the top stones bone dry, the next layer down wet.
Everyone will be familiar with the gentle swoosh sound of small shingle as the waves come and go. On Chesil Beach, the wave interaction with the large pebbles produces a remarkable clattering and clacking sound that is mesmerising to listen to. Luckily I remembered the video button on my camera, so here’s a very short movie to demonstrate this.
Here is a collection of photos of the stones around us as we sat by the sea. The apparently uniform colouring of the beach from a distance turns out to be a blend of many soft, subtle colours and shades – not least because the stones are of different materials. The geology of the beach would make a good post for another occasion, but not by me!

Finally, a reminder of the area’s more turbulent past – a time of press-gangs, blackjacks and daggers swiftly drawn in candlelit taverns. A portland stone plaque in the Church of St George, Portland gives eloquent testimony to an era of lawlessness.
Later, and perhaps in consequence, Portland became the centre of the Knuckleduster-making industry that flourished on the island until the passing of the Prevention of Crime Act 1953, which defined and prohibited “the carrying of offensive weapons without lawful authority or reasonable excuse”. The industry, already in sharp decline in the 1930s, was by then nearly defunct, with only one craftsman still active on Portland. In 2012, a large and elegant sculpture to commemorate this unusual aspect of Portland’s history was installed in a prominent position, commanding a fine view over the the Chesil Beach to Weymouth and the mainland beyond.
The ‘Knuckleduster Memorial’ also marked Weymouth & Portland as the Olympic Sailing venue
* I’m reluctant to endorse the enthusiastic marketing of large swathes of the Dorset seaboard as ‘The Jurassic Coast’. There are fossils in many places. They are fun to look for. More fun to find. Best not to turn it into a Theme Park. I’ll leave it at that.
