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.

The answer to that question can tell us a lot about how the early Earth worked. According to some folks, plate tectonics was very similar to today. To others, Earth was a very alien world indeed. Along the way, we'll visit trenches off the coast of Japan, and turn our hands into tectonic plates. Dylan also has an exciting announcement : he has a new visiting professor job at Gustavus Adolphus College in Minnesota! Thanks to everyone for their support.
