This is where you’ll find us tomorrow, shucking oysters at the World Stone Skimming Championships on Easdale Island.
I’ve followed the Scottish Geologist for some time - her enthusiasm and knowledge is brilliant to listen to. And there is plenty of geology to get excited about on Easdale!! Should be a great day.
Hope to see you there - mind and come and say hello oyster lovers!!
Want to learn why Easdale Slate is so GREAT!
Our official championships geologist will be running 1 hour education tours of Easdale Island on Championship Day.

Slate, Sea & Skimming: A Geology Tour of Easdale with — Stone Skimming Championships Special
Join for a unique geology adventure on Easdale Island — timed to coincide with the annual Stone Skimming Championships! This special tour blends hands-on geological exploration with the fun of one of Scotland’s most iconic community events. As the skimmers compete for the perfect ripple, you’ll uncover the ancient forces that shaped Easdale and the Mid-Argyll Slate Belt that made it world-famous.
What to Expect
🪨 Uncover the Story of Easdale Slate
Explore the Easdale Slate Formation, part of the Dalradian Supergroup — metamorphosed over 500 million years ago.
📜 Industrial Geology & Quarry History
Hear how Easdale was once the heart of the Scottish slate trade, with thousands of tons quarried and exported worldwide.
Explore how quarrying shaped not just the geology, but the history and communities of Easdale and neighbouring islands.
🧠 Stone Skimming Meets Stone Science
While skimmers compete for the flattest, roundest, fastest stone, you’ll learn what makes a good skimming stone geologically:
Shape and flatness from bedding and cleavage planes
Density and hardness from slate mineralogy
Surface texture that supports multiple skips
Test out your geological insights by selecting your own “skimming slate” from permitted pebble areas.
🦴 Hands-On Geological Investigations
Sketch geological sections and learn how geologists reconstruct rock histories in the field.
This tour is perfect for:
Participants in or spectators of the Stone Skimming Championships
Anyone curious about how everyday rocks become geological treasures
