Let's take a relaxing trip back to Scotland and explore geology through the details of a single boulder. This time, glacial effects, the cyclical nature of formations, life in the past, and ideas about how an ocean boulder ended up in a river valley. So much lovely speculative imagery to delight your dreams! Help us stay ad-free and 100% listener-supported!
