Anglesey is an internationally recognised Geopark: it has attracted geologists for centuries and there has been deep study and argument about the development of its fascinating structure. The island is one of the most geologically interesting areas within the UK.
Anglesey became an island around 10,000 years ago, after the last Ice Age, when ice melted and sea levels rose. There is a seismic fault which runs along the Menai Strait and there are occassional earth shocks or tremors – there was one in early 2015.
You don’t need to be a geologist to spend the day exploring the island’s stunning Coastal Path, or one of the many Geo Trails where you will see that our treasured rock formations come in all shapes and sizes, colours and structures and give vital clues to how the land has evolved.
These rocks span 4 eras and 12 geological periods and are often the reason behind the extraordinary range of plants and animals which call the island their home.,/p>
