With a huge tidal range of up to eight metres, the Menai Straits, the body of water which seperates the Isle of Anglesey from the North Wales coast, is a constantly changing visual feast.
One of my favourite spots to watch the tide ebbing and flowing is on the Anglesey side of the Straits, near the Sea Life Centre (well worth a visit in its own right).
This gives a great view out over the water to the historic town of Caernarfon and the mountains of Snowdonia beyond, but there's also a dilapidated concrete and wooden jetty sticking out across the Straits that gets alternately covered and exposed by the rising and falling of the tide twice a day.
Following a day spent exploring the beauties of Snowdonia, and with a picnic tea on the back seat of the car, my wife Liz and I decided to spend the end of the day here.
We arrived just after the turn of the tide, and following a stroll up and down the seashore we settled down to eat our picnic as the highest point of the jetty started to emerge from under the sea.
An ideal situation for a time lapse, so while Liz got stuck into her knitting (socks for one of our grandsons) I headed down to the water's edge, plonked my tripod and camera down into the shallow sea and set off recording the stills for this time lapse video, showing that old jetty emerging from the Straits.
The tide moved with its usual, though still suprising, rapidity and it only took an hour and a half of filming for the jetty to become fully exposed.
One interesting thing (apart from the tide) that is visible on the time lapse but that I didn't notice at the time is the movement of dozens of tiny molluscs on the exposed concrete of the jetty.
No wonder this place is so popular with seabirds.
