100 great geosites

The UK and Ireland feature some of the most diverse and beautiful geology in the world, spanning most of geological time, from the oldest Pre-Cambrian rocks to the youngest Quarternary sediments. As part of Earth Science Week 2014, The Geological Society and partner organisations are celebrating this unique geo-heritage by launching a list of 100 Great Geosites across the UK and Ireland.

More than 400 sites have been nominated, and we need your help to whittle the list down to 100! We’ve split the sites into 10 categories – you can vote for one site in each. Of course, many of the sites could fall into more than one category but we have tried to pick the most relevant one.

The site with the most votes in each category will automatically be included in the final list as a ‘People’s Favourite’, so your votes will make a big difference! You have until Monday 22 September to vote. Photographs and more information about each site can be found on our Flickr pages – just follow the links below.
