EarthCache weekend – Explore Edinburgh’s geology

The dramatic and beautiful city of Edinburgh is draped over an impressive topography that reflects a variety of bedrock formed by different processes and a long story of erosion, particularly during the Ice Age of the last 2 million years. In the city and in the surrounding countryside, this geology and topography has been used by people over thousands of years, in many different ways: for habitation and defence, farming and fuel and as inspiration for a rich culture. It has inspired great geological thinkers too, especially the father of modern geology, James Hutton, who spent most of his life in Edinburgh and discovered one of the world’s most significant geological sites at Siccar Point.

EarthCaches in Edinburgh

This remarkable story of geology and people has resulted in many EarthCaches being established in the city and the surrounding area. An EarthCache is a specific location that people can visit to learn about geology. EarthCaches are part of geocaching (an adventure game based around the use of GPS to find caches of small hidden treasures) but an EarthCache doesn’t involve a physical cache, rather it involves visiting a specific location and learning about our planet.

Existing EarthCaches in Edinburgh explore the geology of important sites such as Siccar Point, Holyrood Park and the Pentland Hills, and the human story of geological investigation and the use of materials. To celebrate this, Edinburgh Geological Society is hosting a weekend of events focussed on EarthCaches.

If you have any questions about the weekend, please contact Angus Miller, EGS Promotion Secretary, promotion@edinburghgeolsoc.org.
