Bedrock will explore the first 90% of Earth’s past, a time known as the Precambrian Era. Before humans, before dinosaurs… there was the Precambrian. The Earth was an incredibly alien world, but not a dead one. Along the way, you will build a mental toolkit to see the world like a geologist. You will never look at a mountain, the moon, or pond scum in quite the same way again. Welcome to Bedrock.

Let's start with the most common rocks in the region: what are they and what stories do they tell about the world 3.9 billion years ago? Along the way, we'll weave a tapestry of stone, boil some rocks, and learn a bit about Dylan's birthstone. Extra credit: try the Play-Doh experiment from this episode, or make some stone soup.
